It adds a significant overhead in terms of performance and memory +consumption so we suggest to enable it only if it is really needed. + +Note that Node.js has a variety of issues with high-performance compression, +where increased concurrency, especially on Linux, can lead to [catastrophic +memory fragmentation][node-zlib-bug] and slow performance. If you intend to use +permessage-deflate in production, it is worthwhile to set up a test +representative of your workload and ensure Node.js/zlib will handle it with +acceptable performance and memory usage. + +Tuning of permessage-deflate can be done via the options defined below. You can +also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly +into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs]. + +See [the docs][ws-server-options] for more options. + +```js +const WebSocket = require('ws'); + +const wss = new WebSocket.Server({ + port: 8080, + perMessageDeflate: { + zlibDeflateOptions: { + // See zlib defaults. + chunkSize: 1024, + memLevel: 7, + level: 3 + }, + zlibInflateOptions: { + chunkSize: 10 * 1024 + }, + // Other options settable: + clientNoContextTakeover: true, // Defaults to negotiated value. + serverNoContextTakeover: true, // Defaults to negotiated value. + serverMaxWindowBits: 10, // Defaults to negotiated value. + // Below options specified as default values. + concurrencyLimit: 10, // Limits zlib concurrency for perf. + threshold: 1024 // Size (in bytes) below which messages + // should not be compressed. + } +}); +``` + +The client will only use the extension if it is supported and enabled on the +server. To always disable the extension on the client set the +`perMessageDeflate` option to `false`. + +```js +const WebSocket = require('ws'); + +const ws = new WebSocket('ws://www.host.com/path', { + perMessageDeflate: false +}); +``` + +## Usage examples + +### Sending and receiving text data + +```js +const WebSocket = require('ws'); + +const ws = new WebSocket('ws://www.host.com/path'); + +ws.on('open', function open() { + ws.send('something'); +}); + +ws.on('message', function incoming(data) { + console.log(data); +}); +``` + +### Sending binary data + +```js +const WebSocket = require('ws'); + +const ws = new WebSocket('ws://www.host.com/path'); + +ws.on('open', function open() { + const array = new Float32Array(5); + + for (var i = 0; i < array.length; ++i) { + array[i] = i / 2; + } + + ws.send(array); +}); +``` + +### Simple server + +```js +const WebSocket = require('ws'); + +const wss = new WebSocket.Server({ port: 8080 }); + +wss.on('connection', function connection(ws) { + ws.on('message', function incoming(message) { + console.log('received: %s', message); + }); + + ws.send('something'); +}); +``` + +### External HTTP/S server + +```js +const fs = require('fs'); +const https = require('https'); +const WebSocket = require('ws'); + +const server = https.createServer({ + cert: fs.readFileSync('/path/to/cert.pem'), + key: fs.readFileSync('/path/to/key.pem') +}); +const wss = new WebSocket.Server({ server }); + +wss.on('connection', function connection(ws) { + ws.on('message', function incoming(message) { + console.log('received: %s', message); + }); + + ws.send('something'); +}); + +server.listen(8080); +``` + +### Multiple servers sharing a single HTTP/S server + +```js +const http = require('http'); +const WebSocket = require('ws'); +const url = require('url'); + +const server = http.createServer(); +const wss1 = new WebSocket.Server({ noServer: true }); +const wss2 = new WebSocket.Server({ noServer: true }); + +wss1.on('connection', function connection(ws) { + // ... +}); + +wss2.on('connection', function connection(ws) { + // ... +}); + +server.on('upgrade', function upgrade(request, socket, head) { + const pathname = url.parse(request.url).pathname; + + if (pathname === '/foo') { + wss1.handleUpgrade(request, socket, head, function done(ws) { + wss1.emit('connection', ws, request); + }); + } else if (pathname === '/bar') { + wss2.handleUpgrade(request, socket, head, function done(ws) { + wss2.emit('connection', ws, request); + }); + } else { + socket.destroy(); + } +}); + +server.listen(8080); +``` + +### Client authentication + +```js +const http = require('http'); +const WebSocket = require('ws'); + +const server = http.createServer(); +const wss = new WebSocket.Server({ noServer: true }); + +wss.on('connection', function connection(ws, request, client) { + ws.on('message', function message(msg) { + console.log(`Received message ${msg} from user ${client}`); + }); +}); + +server.on('upgrade', function upgrade(request, socket, head) { + // This function is not defined on purpose.

The closest untrusted address is +returned. + +```js +proxyaddr(req, function (addr) { return addr === '127.0.0.1' }) +proxyaddr(req, function (addr, i) { return i < 1 }) +``` + +The `trust` arugment may also be a single IP address string or an +array of trusted addresses, as plain IP addresses, CIDR-formatted +strings, or IP/netmask strings. + +```js +proxyaddr(req, '127.0.0.1') +proxyaddr(req, ['127.0.0.0/8', '10.0.0.0/8']) +proxyaddr(req, ['127.0.0.0/255.0.0.0', '192.168.0.0/255.255.0.0']) +``` + +This module also supports IPv6. Your IPv6 addresses will be normalized +automatically (i.e. `fe80::00ed:1` equals `fe80:0:0:0:0:0:ed:1`). + +```js +proxyaddr(req, '::1') +proxyaddr(req, ['::1/128', 'fe80::/10']) +``` + +This module will automatically work with IPv4-mapped IPv6 addresses +as well to support node.js in IPv6-only mode. This means that you do +not have to specify both `::ffff:a00:1` and `10.0.0.1`. + +As a convenience, this module also takes certain pre-defined names +in addition to IP addresses, which expand into IP addresses: + +```js +proxyaddr(req, 'loopback') +proxyaddr(req, ['loopback', 'fc00:ac:1ab5:fff::1/64']) +``` + + * `loopback`: IPv4 and IPv6 loopback addresses (like `::1` and + `127.0.0.1`). + * `linklocal`: IPv4 and IPv6 link-local addresses (like + `fe80::1:1:1:1` and `169.254.0.1`). + * `uniquelocal`: IPv4 private addresses and IPv6 unique-local + addresses (like `fc00:ac:1ab5:fff::1` and `192.168.0.1`). + +When `trust` is specified as a function, it will be called for each +address to determine if it is a trusted address. The function is +given two arguments: `addr` and `i`, where `addr` is a string of +the address to check and `i` is a number that represents the distance +from the socket address. + +### proxyaddr.all(req, [trust]) + +Return all the addresses of the request, optionally stopping at the +first untrusted. This array is ordered from closest to furthest +(i.e. `arr[0] === req.connection.remoteAddress`). + +```js +proxyaddr.all(req) +``` + +The optional `trust` argument takes the same arguments as `trust` +does in `proxyaddr(req, trust)`. + +```js +proxyaddr.all(req, 'loopback') +``` + +### proxyaddr.compile(val) + +Compiles argument `val` into a `trust` function. This function takes +the same arguments as `trust` does in `proxyaddr(req, trust)` and +returns a function suitable for `proxyaddr(req, trust)`. + +```js +var trust = proxyaddr.compile('loopback') +var addr = proxyaddr(req, trust) +``` + +This function is meant to be optimized for use against every request. +It is recommend to compile a trust function up-front for the trusted +configuration and

Always be careful with this option. + +```javascript +var protoObject = qs.parse('a[hasOwnProperty]=b', { allowPrototypes: true }); +assert.deepEqual(protoObject, { a: { hasOwnProperty: 'b' } }); +``` + +URI encoded strings work too: + +```javascript +assert.deepEqual(qs.parse('a%5Bb%5D=c'), { + a: { b: 'c' } +}); +``` + +You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`: + +```javascript +assert.deepEqual(qs.parse('foo[bar][baz]=foobarbaz'), { + foo: { + bar: { + baz: 'foobarbaz' + } + } +}); +``` + +By default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like +`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be: + +```javascript +var expected = { + a: { + b: { + c: { + d: { + e: { + f: { + '[g][h][i]': 'j' + } + } + } + } + } + } +}; +var string = 'a[b][c][d][e][f][g][h][i]=j'; +assert.deepEqual(qs.parse(string), expected); +``` + +This depth can be overridden by passing a `depth` option to `qs.parse(string, [options])`: + +```javascript +var deep = qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 }); +assert.deepEqual(deep, { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } }); +``` + +The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number. + +For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option: + +```javascript +var limited = qs.parse('a=b&c=d', { parameterLimit: 1 }); +assert.deepEqual(limited, { a: 'b' }); +``` + +To bypass the leading question mark, use `ignoreQueryPrefix`: + +```javascript +var prefixed = qs.parse('?a=b&c=d', { ignoreQueryPrefix: true }); +assert.deepEqual(prefixed, { a: 'b', c: 'd' }); +``` + +An optional delimiter can also be passed: + +```javascript +var delimited = qs.parse('a=b;c=d', { delimiter: ';' }); +assert.deepEqual(delimited, { a: 'b', c: 'd' }); +``` + +Delimiters can be a regular expression too: + +```javascript +var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ }); +assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' }); +``` + +Option `allowDots` can be used to enable dot notation: + +```javascript +var withDots = qs.parse('a.b=c', { allowDots: true }); +assert.deepEqual(withDots, { a: { b: 'c' } }); +``` + +If you have to deal with legacy browsers or services, there's +also support for decoding percent-encoded octets as iso-8859-1: + +```javascript +var oldCharset = qs.parse('a=%A7', { charset: 'iso-8859-1' }); +assert.deepEqual(oldCharset, { a: '§' }); +``` + +Some services add an initial `utf8=✓` value to forms so that old +Internet Explorer versions are more likely to submit the form as +utf-8. Additionally, the server can check the value against wrong +encodings of the checkmark character and detect that a query string +or `application/x-www-form-urlencoded` body was *not* sent as +utf-8, eg. if the form had an `accept-charset` parameter or the +containing page had a different character set. + +**qs** supports this mechanism via the `charsetSentinel` option. +If specified, the `utf8` parameter will be omitted from the +returned object. It will be used to switch to `iso-8859-1`/`utf-8` +mode depending on how the checkmark is encoded. + +**Important**: When you specify both the `charset` option and the +`charsetSentinel` option, the `charset` will be overridden when +the request contains a `utf8` parameter from which the actual +charset can be deduced. In that sense the `charset` will behave +as the default charset rather than the authoritative charset. + +```javascript +var detectedAsUtf8 = qs.parse('utf8=%E2%9C%93&a=%C3%B8', { + charset: 'iso-8859-1', + charsetSentinel: true +}); +assert.deepEqual(detectedAsUtf8, { a: 'ø' }); + +// Browsers encode the checkmark as ✓ when submitting as iso-8859-1: +var detectedAsIso8859_1 = qs.parse('utf8=%26%2310003%3B&a=%F8', { + charset: 'utf-8', + charsetSentinel: true +}); +assert.deepEqual(detectedAsIso8859_1, { a: 'ø' }); +``` + +If you want to decode the `&#...;` syntax to the actual character, +you can specify the `interpretNumericEntities` option as well: + +```javascript +var detectedAsIso8859_1 = qs.parse('a=%26%239786%3B', { + charset: 'iso-8859-1', + interpretNumericEntities: true +}); +assert.deepEqual(detectedAsIso8859_1, { a: '☺' }); +``` + +It also works when the charset has been detected in `charsetSentinel` +mode. + +### Parsing Arrays + +**qs** can also parse arrays using a similar `[]` notation: + +```javascript +var withArray = qs.parse('a[]=b&a[]=c'); +assert.deepEqual(withArray, { a: ['b', 'c'] }); +``` + +You may specify an index as well: + +```javascript +var withIndexes = qs.parse('a[1]=c&a[0]=b'); +assert.deepEqual(withIndexes, { a: ['b', 'c'] }); +``` + +Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number +to create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving +their order: + +```javascript +var noSparse = qs.parse('a[1]=b&a[15]=c'); +assert.deepEqual(noSparse, { a: ['b', 'c'] }); +``` + +Note that an empty string is also a value, and will be preserved: + +```javascript +var withEmptyString = qs.parse('a[]=&a[]=b'); +assert.deepEqual(withEmptyString, { a: ['', 'b'] }); + +var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c'); +assert.deepEqual(withIndexedEmptyString, { a: ['b', '', 'c'] }); +``` + +**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will +instead be converted to an object with the index as the key. This is needed to handle cases when someone sent, for example, `a[999999999]` and it will take significant time to iterate over this huge array. + +```javascript +var withMaxIndex = qs.parse('a[100]=b'); +assert.deepEqual(withMaxIndex, { a: { '100': 'b' } }); +``` + +This limit can be overridden by passing an `arrayLimit` option: + +```javascript +var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 }); +assert.deepEqual(withArrayLimit, { a: { '1': 'b' } }); +``` + +To disable array parsing entirely, set `parseArrays` to `false`. + +```javascript +var noParsingArrays = qs.parse('a[]=b', { parseArrays: false }); +assert.deepEqual(noParsingArrays, { a: { '0': 'b' } }); +``` + +If you mix notations, **qs** will merge the two items into an object: + +```javascript +var mixedNotation = qs.parse('a[0]=b&a[b]=c'); +assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } }); +``` + +You can also create arrays of objects: + +```javascript +var arraysOfObjects = qs.parse('a[][b]=c'); +assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] }); +``` + +Some people use comma to join array, **qs** can parse it: +```javascript +var arraysOfObjects = qs.parse('a=b,c', { comma: true }) +assert.deepEqual(arraysOfObjects, { a: ['b', 'c'] }) +``` +(_this cannot convert nested objects, such as `a={b:1},{c:d}`_) + +### Stringifying + +[](#preventEval) +```javascript +qs.stringify(object, [options]); +``` + +When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect: + +```javascript +assert.equal(qs.stringify({ a: 'b' }), 'a=b'); +assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c'); +``` + +This encoding can be disabled by setting the `encode` option to `false`: + +```javascript +var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false }); +assert.equal(unencoded, 'a[b]=c'); +``` + +Encoding can be disabled for keys by setting the `encodeValuesOnly` option to `true`: +```javascript +var encodedValues = qs.stringify( + { a: 'b', c: ['d', 'e=f'], f: [['g'], ['h']] }, + { encodeValuesOnly: true } +); +assert.equal(encodedValues,'a=b&c[0]=d&c[1]=e%3Df&f[0][0]=g&f[1][0]=h'); +``` + +This encoding can also be replaced by a custom encoding method set as `encoder` option: + +```javascript +var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) { + // Passed in values `a`, `b`, `c` + return // Return encoded string +}}) +``` + +_(Note: the `encoder` option does not apply if `encode` is `false`)_ + +Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values: + +```javascript +var decoded = qs.parse('x=z', { decoder: function (str) { + // Passed in values `x`, `z` + return // Return decoded string +}}) +``` + +Examples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage. + +When arrays are stringified, by default they are given explicit indices: + +```javascript +qs.stringify({ a: ['b', 'c', 'd'] }); +// 'a[0]=b&a[1]=c&a[2]=d' +``` + +You may override this by setting the `indices` option to `false`: + +```javascript +qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false }); +// 'a=b&a=c&a=d' +``` + +You may use the `arrayFormat` option to specify the format of the output array: + +```javascript +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' }) +// 'a[0]=b&a[1]=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' }) +// 'a[]=b&a[]=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' }) +// 'a=b&a=c' +qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'comma' }) +// 'a=b,c' +``` + +When objects are stringified, by default they use bracket notation: + +```javascript +qs.stringify({ a: { b: { c: 'd', e: 'f' } } }); +// 'a[b][c]=d&a[b][e]=f' +``` + +You may override this to use dot notation by setting the `allowDots` option to `true`: + +```javascript +qs.stringify({ a: { b: { c: 'd', e: 'f' } } }, { allowDots: true }); +// 'a.b.c=d&a.b.e=f' +``` + +Empty strings and null values will omit the value, but the equals sign (=) remains in place: + +```javascript +assert.equal(qs.stringify({ a: '' }), 'a='); +``` + +Key with no values (such as an empty object or array) will return nothing: + +```javascript +assert.equal(qs.stringify({ a: [] }), ''); +assert.equal(qs.stringify({ a: {} }), ''); +assert.equal(qs.stringify({ a: [{}] }), ''); +assert.equal(qs.stringify({ a: { b: []} }), ''); +assert.equal(qs.stringify({ a: { b: {}} }), ''); +``` + +Properties that are set to `undefined` will be omitted entirely: + +```javascript +assert.equal(qs.stringify({ a: null, b: undefined }), 'a='); +``` + +The query string may optionally be prepended with a question mark: + +```javascript +assert.equal(qs.stringify({ a: 'b', c: 'd' }, { addQueryPrefix: true }), '?a=b&c=d'); +``` + +The delimiter may be overridden with stringify as well: + +```javascript +assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d'); +``` + +If you only want to override the serialization of `Date` objects, you can provide a `serializeDate` option: + +```javascript +var date = new Date(7); +assert.equal(qs.stringify({ a: date }), 'a=1970-01-01T00:00:00.007Z'.replace(/:/g, '%3A')); +assert.equal( + qs.stringify({ a: date }, { serializeDate: function (d) { return d.getTime(); } }), + 'a=7' +); +``` + +You may use the `sort` option to affect the order of parameter keys: + +```javascript +function alphabeticalSort(a, b) { + return a.localeCompare(b); +} +assert.equal(qs.stringify({ a: 'c', z: 'y', b : 'f' }, { sort: alphabeticalSort }), 'a=c&b=f&z=y'); +``` + +Finally, you can use the `filter` option to restrict which keys will be included in the stringified output. +If you pass a function, it will be called for each key to obtain the replacement value. Otherwise, if you +pass an array, it will be used to select properties and array indices for stringification: + +```javascript +function filterFunc(prefix, value) { + if (prefix == 'b') { + // Return an `undefined` value to omit a property. + return; + } + if (prefix == 'e[f]') { + return value.getTime(); + } + if (prefix == 'e[g][0]') { + return value * 2; + } + return value; +} +qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc }); +// 'a=b&c=d&e[f]=123&e[g][0]=4' +qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] }); +// 'a=b&e=f' +qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] }); +// 'a[0]=b&a[2]=d' +``` + +### Handling of `null` values + +By default, `null` values are treated like empty strings: + +```javascript +var withNull = qs.stringify({ a: null, b: '' }); +assert.equal(withNull, 'a=&b='); +``` + +Parsing does not distinguish between parameters with and without equal signs. Both are converted to empty strings. + +```javascript +var equalsInsensitive = qs.parse('a&b='); +assert.deepEqual(equalsInsensitive, { a: '', b: '' }); +``` + +To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null` +values have no `=` sign: + +```javascript +var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true }); +assert.equal(strictNull, 'a&b='); +``` + +To parse values without `=` back to `null` use the `strictNullHandling` flag: + +```javascript +var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true }); +assert.deepEqual(parsedStrictNull, { a: null, b: '' }); +``` + +To completely skip rendering keys with `null` values, use the `skipNulls` flag: + +```javascript +var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true }); +assert.equal(nullsSkipped, 'a=b'); +``` + +If you're communicating with legacy systems, you can switch to `iso-8859-1` +using the `charset` option: + +```javascript +var iso = qs.stringify({ æ: 'æ' }, { charset: 'iso-8859-1' }); +assert.equal(iso, '%E6=%E6'); +``` + +Characters that don't exist in `iso-8859-1` will be converted to numeric +entities, similar to what browsers do: + +```javascript +var numeric = qs.stringify({ a: '☺' }, { charset: 'iso-8859-1' }); +assert.equal(numeric, 'a=%26%239786%3B'); +``` + +You can use the `charsetSentinel` option to announce the character by +including an `utf8=✓` parameter with the proper encoding if the checkmark, +similar to what Ruby on Rails and others do when submitting forms. + +```javascript +var sentinel = qs.stringify({ a: '☺' }, { charsetSentinel: true }); +assert.equal(sentinel, 'utf8=%E2%9C%93&a=%E2%98%BA'); + +var isoSentinel = qs.stringify({ a: 'æ' }, { charsetSentinel: true, charset: 'iso-8859-1' }); +assert.equal(isoSentinel, 'utf8=%26%2310003%3B&a=%E6'); +``` + +### Dealing with special character sets + +By default the encoding and decoding of characters is done in `utf-8`, +and `iso-8859-1` support is also built in via the `charset` parameter. + +If you wish to encode querystrings to a different character set (i.e. +[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the +[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library: + +```javascript +var encoder = require('qs-iconv/encoder')('shift_jis'); +var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder }); +assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I'); +``` + +This also works for decoding of query strings: + +```javascript +var decoder = require('qs-iconv/decoder')('shift_jis'); +var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder }); +assert.deepEqual(obj, { a: 'こんにちは！' }); +``` + +### RFC 3986 and RFC 1738 space encoding + +RFC3986 used as default option and encodes ' ' to *%20* which is backward compatible. +In the same time, output can be stringified as per RFC1738 with ' ' equal to '+'. + +``` +assert.equal(qs.stringify({ a: 'b c' }), 'a=b%20c'); +assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC3986' }), 'a=b%20c'); +assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC1738' }), 'a=b+c'); +``` + +[1]: https://npmjs.org/package/qs +[2]: http://versionbadg.es/ljharb/qs.svg +[3]: https://api.travis-ci.org/ljharb/qs.svg +[4]: https://travis-ci.org/ljharb/qs +[5]: https://david-dm.org/ljharb/qs.svg +[6]: https://david-dm.org/ljharb/qs +[7]: https://david-dm.org/ljharb/qs/dev-status.svg +[8]: https://david-dm.org/ljharb/qs?type=dev +[9]: https://ci.testling.com/ljharb/qs.png +[10]: https://ci.testling.com/ljharb/qs +[11]: https://nodei.co/npm/qs.png?downloads=true&stars=true +[license-image]: http://img.shields.io/npm/l/qs.svg +[license-url]: LICENSE +[downloads-image]: http://img.shields.io/npm/dm/qs.svg +[downloads-url]: http://npm-stat.com/charts.html?package=qs diff --git a/node_modules/qs/dist/qs.js b/node_modules/qs/dist/qs.js new file mode 100644 index 0000000..17f4e60 --- /dev/null +++ b/node_modules/qs/dist/qs.js @@ -0,0 +1,782 @@ +(function(f){if(typeof exports==="object"&&typeof module!=="undefined"){module.exports=f()}else if(typeof define==="function"&&define.amd){define([],f)}else{var g;if(typeof window!=="undefined"){g=window}else if(typeof global!=="undefined"){g=global}else if(typeof self!=="undefined"){g=self}else{g=this}g.Qs = f()}})(function(){var define,module,exports;return (function(){function r(e,n,t){function o(i,f){if(!n[i]){if(!e[i]){var c="function"==typeof require&&require;if(!f&&c)return c(i,!0);if(u)return u(i,!0);var a=new Error("Cannot find module '"+i+"'");throw a.code="MODULE_NOT_FOUND",a}var p=n[i]={exports:{}};e[i][0].call(p.exports,function(r){var n=e[i][1][r];return o(n||r)},p,p.exports,r,e,n,t)}return n[i].exports}for(var u="function"==typeof require&&require,i=0;i -1) { + val = val.split(',');

This allows applications to avoid the garbage collection overhead of +creating many individually allocated Buffers. This approach improves both +performance and memory usage by eliminating the need to track and cleanup as +many `Persistent` objects. + +However, in the case where a developer may need to retain a small chunk of +memory from a pool for an indeterminate amount of time, it may be appropriate +to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then +copy out the relevant bits. + +```js +// need to keep around a few small chunks of memory +const store = []; + +socket.on('readable', () => { + const data = socket.read(); + // allocate for retained data + const sb = Buffer.allocUnsafeSlow(10); + // copy the data into the new allocation + data.copy(sb, 0, 0, 10); + store.push(sb); +}); +``` + +Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after* +a developer has observed undue memory retention in their applications. + +A `TypeError` will be thrown if `size` is not a number. + +### All the Rest + +The rest of the `Buffer` API is exactly the same as in node.js. +[See the docs](https://nodejs.org/api/buffer.html). + + +## Related links + +- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660) +- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4) + +## Why is `Buffer` unsafe? + +Today, the node.js `Buffer` constructor is overloaded to handle many different argument +types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.), +`ArrayBuffer`, and also `Number`. + +The API is optimized for convenience: you can throw any type at it, and it will try to do +what you want. + +Because the Buffer constructor is so powerful, you often see code like this: + +```js +// Convert UTF-8 strings to hex +function toHex (str) { + return new Buffer(str).toString('hex') +} +``` + +***But what happens if `toHex` is called with a `Number` argument?*** + +### Remote Memory Disclosure + +If an attacker can make your program call the `Buffer` constructor with a `Number` +argument, then they can make it allocate uninitialized memory from the node.js process. +This could potentially disclose TLS private keys, user data, or database passwords. + +When the `Buffer` constructor is passed a `Number` argument, it returns an +**UNINITIALIZED** block of memory of the specified `size`.

It's surprisingly common to forget to check the type of your variables in a +dynamically-typed language like JavaScript. + +Usually the consequences of assuming the wrong type is that your program crashes with an +uncaught exception. But the failure mode for forgetting to check the type of arguments to +the `Buffer` constructor is more catastrophic. + +Here's an example of a vulnerable service that takes a JSON payload and converts it to +hex: + +```js +// Take a JSON payload {str: "some string"} and convert it to hex +var server = http.createServer(function (req, res) { + var data = '' + req.setEncoding('utf8') + req.on('data', function (chunk) { + data += chunk + }) + req.on('end', function () { + var body = JSON.parse(data) + res.end(new Buffer(body.str).toString('hex')) + }) +}) + +server.listen(8080) +``` + +In this example, an http client just has to send: + +```json +{ + "str": 1000 +} +``` + +and it will get back 1,000 bytes of uninitialized memory from the server. + +This is a very serious bug. It's similar in severity to the +[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process +memory by remote attackers. + + +### Which real-world packages were vulnerable? + +#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht) + +[Mathias Buus](https://github.com/mafintosh) and I +([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages, +[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow +anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get +them to reveal 20 bytes at a time of uninitialized memory from the node.js process. + +Here's +[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8) +that fixed it. We released a new fixed version, created a +[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all +vulnerable versions on npm so users will get a warning to upgrade to a newer version. + +#### [`ws`](https://www.npmjs.com/package/ws) + +That got us wondering if there were other vulnerable packages. Sure enough, within a short +period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the +most popular WebSocket implementation in node.js. + +If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as +expected, then uninitialized server memory would be disclosed to the remote peer. + +These were the vulnerable methods: + +```js +socket.send(number) +socket.ping(number) +socket.pong(number) +``` + +Here's a vulnerable socket server with some echo functionality: + +```js +server.on('connection', function (socket) { + socket.on('message', function (message) { + message = JSON.parse(message) + if (message.type === 'echo') { + socket.send(message.data) // send back the user's message + } + }) +}) +``` + +`socket.send(number)` called on the server, will disclose server memory. + +Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue +was fixed, with a more detailed explanation. Props to +[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the +[Node Security Project disclosure](https://nodesecurity.io/advisories/67). + + +### What's the solution? + +It's important that node.js offers a fast way to get memory otherwise performance-critical +applications would needlessly get a lot slower. + +But we need a better way to *signal our intent* as programmers. **When we want +uninitialized memory, we should request it explicitly.** + +Sensitive functionality should not be packed into a developer-friendly API that loosely +accepts many different types. This type of API encourages the lazy practice of passing +variables in without checking the type very carefully. + +#### A new API: `Buffer.allocUnsafe(number)` + +The functionality of creating buffers with uninitialized memory should be part of another +API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that +frequently gets user input of all sorts of different types passed into it. + +```js +var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory! + +// Immediately overwrite the uninitialized buffer with data from another buffer +for (var i = 0; i < buf.length; i++) { + buf[i] = otherBuf[i] +} +``` + + +### How do we fix node.js core? + +We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as +`semver-major`) which defends against one case: + +```js +var str = 16 +new Buffer(str, 'utf8') +``` + +In this situation, it's implied that the programmer intended the first argument to be a +string, since they passed an encoding as a second argument. Today, node.js will allocate +uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not +what the programmer intended. + +But this is only a partial solution, since if the programmer does `new Buffer(variable)` +(without an `encoding` parameter) there's no way to know what they intended. If `variable` +is sometimes a number, then uninitialized memory will sometimes be returned. + +### What's the real long-term fix? + +We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when +we need uninitialized memory. But that would break 1000s of packages. + +~~We believe the best solution is to:~~ + +~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~ + +~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~ + +#### Update + +We now support adding three new APIs: + +- `Buffer.from(value)` - convert from any type to a buffer +- `Buffer.alloc(size)` - create a zero-filled buffer +- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size + +This solves the core problem that affected `ws` and `bittorrent-dht` which is +`Buffer(variable)` getting tricked into taking a number argument. + +This way, existing code continues working and the impact on the npm ecosystem will be +minimal. Over time, npm maintainers can migrate performance-critical code to use +`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`. + + +### Conclusion + +We think there's a serious design issue with the `Buffer` API as it exists today. It +promotes insecure software by putting high-risk functionality into a convenient API +with friendly "developer ergonomics". + +This wasn't merely a theoretical exercise because we found the issue in some of the +most popular npm packages. + +Fortunately, there's an easy fix that can be applied today.

This means that these versions of Node.js will *not* receive any updates, even in case of security issues, so using these release lines should be avoided, if at all possible. + +What you would do in this case is to convert all `new Buffer()` or `Buffer()` calls to use `Buffer.alloc()` or `Buffer.from()`, in the following way: + +- For `new Buffer(number)`, replace it with `Buffer.alloc(number)`. +- For `new Buffer(string)` (or `new Buffer(string, encoding)`), replace it with `Buffer.from(string)` (or `Buffer.from(string, encoding)`). +- For all other combinations of arguments (these are much rarer), also replace `new Buffer(...arguments)` with `Buffer.from(...arguments)`. + +Note that `Buffer.alloc()` is also _faster_ on the current Node.js versions than +`new Buffer(size).fill(0)`, which is what you would otherwise need to ensure zero-filling. + +Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor) +or +[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md) +is recommended to avoid accidential unsafe Buffer API usage. + +There is also a [JSCodeshift codemod](https://github.com/joyeecheung/node-dep-codemod#dep005) +for automatically migrating Buffer constructors to `Buffer.alloc()` or `Buffer.from()`. +Note that it currently only works with cases where the arguments are literals or where the +constructor is invoked with two arguments. + +_If you currently support those older Node.js versions and dropping them would be a semver-major change +for you, or if you support older branches of your packages, consider using [Variant 2](#variant-2) +or [Variant 3](#variant-3) on older branches, so people using those older branches will also receive +the fix. That way, you will eradicate potential issues caused by unguarded Buffer API usage and +your users will not observe a runtime deprecation warning when running your code on Node.js 10._ + + +## Variant 2: Use a polyfill + +Utilize [safer-buffer](https://www.npmjs.com/package/safer-buffer) as a polyfill to support older +Node.js versions. + +You would take exacly the same steps as in [Variant 1](#variant-1), but with a polyfill +`const Buffer = require('safer-buffer').Buffer` in all files where you use the new `Buffer` api. + +Make sure that you do not use old `new Buffer` API — in any files where the line above is added, +using old `new Buffer()` API will _throw_. It will be easy to notice that in CI, though. + +Alternatively, you could use [buffer-from](https://www.npmjs.com/package/buffer-from) and/or +[buffer-alloc](https://www.npmjs.com/package/buffer-alloc) [ponyfills](https://ponyfill.com/) — +those are great, the only downsides being 4 deps in the tree and slightly more code changes to +migrate off them (as you would be using e.g. `Buffer.from` under a different name). If you need only +`Buffer.from` polyfilled — `buffer-from` alone which comes with no extra dependencies. + +_Alternatively, you could use [safe-buffer](https://www.npmjs.com/package/safe-buffer) — it also +provides a polyfill, but takes a different approach which has +[it's drawbacks](https://github.com/chalker/safer-buffer#why-not-safe-buffer). It will allow you +to also use the older `new Buffer()` API in your code, though — but that's arguably a benefit, as +it is problematic, can cause issues in your code, and will start emitting runtime deprecation +warnings starting with Node.js 10._ + +Note that in either case, it is important that you also remove all calls to the old Buffer +API manually — just throwing in `safe-buffer` doesn't fix the problem by itself, it just provides +a polyfill for the new API. I have seen people doing that mistake. + +Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor) +or +[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md) +is recommended. + +_Don't forget to drop the polyfill usage once you drop support for Node.js < 4.5.0._ + + +## Variant 3 — manual detection, with safeguards + +This is useful if you create Buffer instances in only a few places (e.g. one), or you have your own +wrapper around them. + +### Buffer(0) + +This special case for creating empty buffers can be safely replaced with `Buffer.concat([])`, which +returns the same result all the way down to Node.js 0.8.x. + +### Buffer(notNumber) + +Before: + +```js +var buf = new Buffer(notNumber, encoding); +``` + +After: + +```js +var buf; +if (Buffer.from && Buffer.from !== Uint8Array.from) { + buf = Buffer.from(notNumber, encoding); +} else { + if (typeof notNumber === 'number') + throw new Error('The "size" argument must be of type number.'); + buf = new Buffer(notNumber, encoding); +} +``` + +`encoding` is optional. + +Note that the `typeof notNumber` before `new Buffer` is required (for cases when `notNumber` argument is not +hard-coded) and _is not caused by the deprecation of Buffer constructor_ — it's exactly _why_ the +Buffer constructor is deprecated.

Before Node.js 8, this buffer contained + *arbitrary memory* for performance reasons, which could include anything ranging from + program source code to passwords and encryption keys. +- `new Buffer('abc')` creates a `Buffer` that contains the UTF-8-encoded version of + the string `'abc'`. A second argument could specify another encoding: For example, + `new Buffer(string, 'base64')` could be used to convert a Base64 string into the original + sequence of bytes that it represents. +- There are several other combinations of arguments. + +This meant that, in code like `var buffer = new Buffer(foo);`, *it is not possible to tell +what exactly the contents of the generated buffer are* without knowing the type of `foo`. + +Sometimes, the value of `foo` comes from an external source. For example, this function +could be exposed as a service on a web server, converting a UTF-8 string into its Base64 form: + +``` +function stringToBase64(req, res) { + // The request body should have the format of `{ string: 'foobar' }` + const rawBytes = new Buffer(req.body.string) + const encoded = rawBytes.toString('base64') + res.end({ encoded: encoded }) +} +``` + +Note that this code does *not* validate the type of `req.body.string`: + +- `req.body.string` is expected to be a string. If this is the case, all goes well. +- `req.body.string` is controlled by the client that sends the request. +- If `req.body.string` is the *number* `50`, the `rawBytes` would be 50 bytes: + - Before Node.js 8, the content would be uninitialized + - After Node.js 8, the content would be `50` bytes with the value `0` + +Because of the missing type check, an attacker could intentionally send a number +as part of the request. Using this, they can either: + +- Read uninitialized memory. This **will** leak passwords, encryption keys and other + kinds of sensitive information. (Information leak) +- Force the program to allocate a large amount of memory. For example, when specifying + `500000000` as the input value, each request will allocate 500MB of memory. + This can be used to either exhaust the memory available of a program completely + and make it crash, or slow it down significantly. (Denial of Service) + +Both of these scenarios are considered serious security issues in a real-world +web server context. + +when using `Buffer.from(req.body.string)` instead, passing a number will always +throw an exception instead, giving a controlled behaviour that can always be +handled by the program. + + +### The `Buffer()` constructor has been deprecated for a while.

You _do_ need to port to the `Buffer.alloc()` and `Buffer.from()` +though. + +See the [porting guide](https://github.com/ChALkeR/safer-buffer/blob/master/Porting-Buffer.md) +for a better description. + +## Why not [safe-buffer](https://npmjs.com/safe-buffer)? + +_In short: while `safe-buffer` serves as a polyfill for the new API, it allows old API usage and +itself contains footguns._ + +`safe-buffer` could be used safely to get the new API while still keeping support for older +Node.js versions (like this module), but while analyzing ecosystem usage of the old Buffer API +I found out that `safe-buffer` is itself causing problems in some cases. + +For example, consider the following snippet: + +```console +$ cat example.unsafe.js +console.log(Buffer(20)) +$ ./node-v6.13.0-linux-x64/bin/node example.unsafe.js + +$ standard example.unsafe.js +standard: Use JavaScript Standard Style (https://standardjs.com) + /home/chalker/repo/safer-buffer/example.unsafe.js:2:13: 'Buffer()' was deprecated since v6. Use 'Buffer.alloc()' or 'Buffer.from()' (use 'https://www.npmjs.com/package/safe-buffer' for '<4.5.0') instead. +``` + +This is allocates and writes to console an uninitialized chunk of memory. +[standard](https://www.npmjs.com/package/standard) linter (among others) catch that and warn people +to avoid using unsafe API. + +Let's now throw in `safe-buffer`! + +```console +$ cat example.safe-buffer.js +const Buffer = require('safe-buffer').Buffer +console.log(Buffer(20)) +$ standard example.safe-buffer.js +$ ./node-v6.13.0-linux-x64/bin/node example.safe-buffer.js + +``` + +See the problem? Adding in `safe-buffer` _magically removes the lint warning_, but the behavior +remains identiсal to what we had before, and when launched on Node.js 6.x LTS — this dumps out +chunks of uninitialized memory. +_And this code will still emit runtime warnings on Node.js 10.x and above._ + +That was done by design. I first considered changing `safe-buffer`, prohibiting old API usage or +emitting warnings on it, but that significantly diverges from `safe-buffer` design. After some +discussion, it was decided to move my approach into a separate package, and _this is that separate +package_. + +This footgun is not imaginary — I observed top-downloaded packages doing that kind of thing, +«fixing» the lint warning by blindly including `safe-buffer` without any actual changes. + +Also in some cases, even if the API _was_ migrated to use of safe Buffer API — a random pull request +can bring unsafe Buffer API usage back to the codebase by adding new calls — and that could go +unnoticed even if you have a linter prohibiting that (becase of the reason stated above), and even +pass CI. _I also observed that being done in popular packages._ + +Some examples: + * [webdriverio](https://github.com/webdriverio/webdriverio/commit/05cbd3167c12e4930f09ef7cf93b127ba4effae4#diff-124380949022817b90b622871837d56cR31) + (a module with 548 759 downloads/month), + * [websocket-stream](https://github.com/maxogden/websocket-stream/commit/c9312bd24d08271687d76da0fe3c83493871cf61) + (218 288 d/m, fix in [maxogden/websocket-stream#142](https://github.com/maxogden/websocket-stream/pull/142)), + * [node-serialport](https://github.com/node-serialport/node-serialport/commit/e8d9d2b16c664224920ce1c895199b1ce2def48c) + (113 138 d/m, fix in [node-serialport/node-serialport#1510](https://github.com/node-serialport/node-serialport/pull/1510)), + * [karma](https://github.com/karma-runner/karma/commit/3d94b8cf18c695104ca195334dc75ff054c74eec) + (3 973 193 d/m, fix in [karma-runner/karma#2947](https://github.com/karma-runner/karma/pull/2947)), + * [spdy-transport](https://github.com/spdy-http2/spdy-transport/commit/5375ac33f4a62a4f65bcfc2827447d42a5dbe8b1) + (5 970 727 d/m, fix in [spdy-http2/spdy-transport#53](https://github.com/spdy-http2/spdy-transport/pull/53)). + * And there are a lot more over the ecosystem. + +I filed a PR at +[mysticatea/eslint-plugin-node#110](https://github.com/mysticatea/eslint-plugin-node/pull/110) to +partially fix that (for cases when that lint rule is used), but it is a semver-major change for +linter rules and presets, so it would take significant time for that to reach actual setups. +_It also hasn't been released yet (2018-03-20)._ + +Also, `safer-buffer` discourages the usage of `.allocUnsafe()`, which is often done by a mistake. +It still supports it with an explicit concern barier, by placing it under +`require('safer-buffer/dangereous')`. + +## But isn't throwing bad? + +Not really. It's an error that could be noticed and fixed early, instead of causing havoc later like +unguarded `new Buffer()` calls that end up receiving user input can do. + +This package affects only the files where `var Buffer = require('safer-buffer').Buffer` was done, so +it is really simple to keep track of things and make sure that you don't mix old API usage with that. +Also, CI should hint anything that you might have missed. + +New commits, if tested, won't land new usage of unsafe Buffer API this way. +_Node.js 10.x also deals with that by printing a runtime depecation warning._ + +### Would it affect third-party modules? + +No, unless you explicitly do an awful thing like monkey-patching or overriding the built-in `Buffer`. +Don't do that. + +### But I don't want throwing… + +That is also fine! + +Also, it could be better in some cases when you don't comprehensive enough test coverage. + +In that case — just don't override `Buffer` and use +`var SaferBuffer = require('safer-buffer').Buffer` instead. + +That way, everything using `Buffer` natively would still work, but there would be two drawbacks: + +* `Buffer.from`/`Buffer.alloc` won't be polyfilled — use `SaferBuffer.from` and + `SaferBuffer.alloc` instead. +* You are still open to accidentally using the insecure deprecated API — use a linter to catch that. + +Note that using a linter to catch accidential `Buffer` constructor usage in this case is strongly +recommended. `Buffer` is not overriden in this usecase, so linters won't get confused. + +## «Without footguns»? + +Well, it is still possible to do _some_ things with `Buffer` API, e.g. accessing `.buffer` property +on older versions and duping things from there. You shouldn't do that in your code, probabably. + +The intention is to remove the most significant footguns that affect lots of packages in the +ecosystem, and to do it in the proper way. + +Also, this package doesn't protect against security issues affecting some Node.js versions, so for +usage in your own production code, it is still recommended to update to a Node.js version +[supported by upstream](https://github.com/nodejs/release#release-schedule). diff --git a/node_modules/safer-buffer/dangerous.js b/node_modules/safer-buffer/dangerous.js new file mode 100644 index 0000000..ca41fdc --- /dev/null +++ b/node_modules/safer-buffer/dangerous.js @@ -0,0 +1,58 @@ +/* eslint-disable node/no-deprecated-api */ + +'use strict' + +var buffer = require('buffer') +var Buffer = buffer.Buffer +var safer = require('./safer.js') +var Safer = safer.Buffer + +var dangerous = {} + +var key + +for (key in safer) { + if (!safer.hasOwnProperty(key)) continue + dangerous[key] = safer[key] +} + +var Dangereous = dangerous.Buffer = {} + +// Copy Safer API +for (key in Safer) { + if (!Safer.hasOwnProperty(key)) continue + Dangereous[key] = Safer[key] +} + +// Copy those missing unsafe methods, if they are present +for (key in Buffer) { + if (!Buffer.hasOwnProperty(key)) continue + if (Dangereous.hasOwnProperty(key)) continue + Dangereous[key] = Buffer[key] +} + +if (!Dangereous.allocUnsafe) { + Dangereous.allocUnsafe = function (size) { + if (typeof size !== 'number') { + throw new TypeError('The "size" argument must be of type number.

Try [serve-static](https://www.npmjs.org/package/serve-static). + +## Installation + +This is a [Node.js](https://nodejs.org/en/) module available through the +[npm registry](https://www.npmjs.com/). Installation is done using the +[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): + +```bash +$ npm install send +``` + +## API + + + +```js +var send = require('send') +``` + +### send(req, path, [options]) + +Create a new `SendStream` for the given path to send to a `res`. The `req` is +the Node.js HTTP request and the `path` is a urlencoded path to send (urlencoded, +not the actual file-system path). + +#### Options + +##### acceptRanges + +Enable or disable accepting ranged requests, defaults to true. +Disabling this will not send `Accept-Ranges` and ignore the contents +of the `Range` request header. + +##### cacheControl + +Enable or disable setting `Cache-Control` response header, defaults to +true. Disabling this will ignore the `immutable` and `maxAge` options. + +##### dotfiles + +Set how "dotfiles" are treated when encountered. A dotfile is a file +or directory that begins with a dot ("."). Note this check is done on +the path itself without checking if the path actually exists on the +disk. If `root` is specified, only the dotfiles above the root are +checked (i.e. the root itself can be within a dotfile when when set +to "deny"). + + - `'allow'` No special treatment for dotfiles. + - `'deny'` Send a 403 for any request for a dotfile. + - `'ignore'` Pretend like the dotfile does not exist and 404. + +The default value is _similar_ to `'ignore'`, with the exception that +this default will not ignore the files within a directory that begins +with a dot, for backward-compatibility. + +##### end + +Byte offset at which the stream ends, defaults to the length of the file +minus 1. The end is inclusive in the stream, meaning `end: 3` will include +the 4th byte in the stream. + +##### etag + +Enable or disable etag generation, defaults to true. + +##### extensions + +If a given file doesn't exist, try appending one of the given extensions, +in the given order. By default, this is disabled (set to `false`). An +example value that will serve extension-less HTML files: `['html', 'htm']`. +This is skipped if the requested file already has an extension. + +##### immutable + +Enable or diable the `immutable` directive in the `Cache-Control` response +header, defaults to `false`. If set to `true`, the `maxAge` option should +also be specified to enable caching. The `immutable` directive will prevent +supported clients from making conditional requests during the life of the +`maxAge` option to check if the file has changed. + +##### index + +By default send supports "index.html" files, to disable this +set `false` or to supply a new index pass a string or an array +in preferred order. + +##### lastModified + +Enable or disable `Last-Modified` header, defaults to true.

The file to serve will be determined by combining `req.url` +with the provided root directory. When a file is not found, instead of +sending a 404 response, this module will instead call `next()` to move on +to the next middleware, allowing for stacking and fall-backs. + +#### Options + +##### acceptRanges + +Enable or disable accepting ranged requests, defaults to true. +Disabling this will not send `Accept-Ranges` and ignore the contents +of the `Range` request header. + +##### cacheControl + +Enable or disable setting `Cache-Control` response header, defaults to +true. Disabling this will ignore the `immutable` and `maxAge` options. + +##### dotfiles + + Set how "dotfiles" are treated when encountered. A dotfile is a file +or directory that begins with a dot ("."). Note this check is done on +the path itself without checking if the path actually exists on the +disk. If `root` is specified, only the dotfiles above the root are +checked (i.e. the root itself can be within a dotfile when set +to "deny"). + + - `'allow'` No special treatment for dotfiles. + - `'deny'` Deny a request for a dotfile and 403/`next()`. + - `'ignore'` Pretend like the dotfile does not exist and 404/`next()`. + +The default value is similar to `'ignore'`, with the exception that this +default will not ignore the files within a directory that begins with a dot. + +##### etag + +Enable or disable etag generation, defaults to true. + +##### extensions + +Set file extension fallbacks. When set, if a file is not found, the given +extensions will be added to the file name and search for. The first that +exists will be served. Example: `['html', 'htm']`. + +The default value is `false`. + +##### fallthrough + +Set the middleware to have client errors fall-through as just unhandled +requests, otherwise forward a client error. The difference is that client +errors like a bad request or a request to a non-existent file will cause +this middleware to simply `next()` to your next middleware when this value +is `true`. When this value is `false`, these errors (even 404s), will invoke +`next(err)`. + +Typically `true` is desired such that multiple physical directories can be +mapped to the same web address or for routes to fill in non-existent files. + +The value `false` can be used if this middleware is mounted at a path that +is designed to be strictly a single file system directory, which allows for +short-circuiting 404s for less overhead. This middleware will also reply to +all methods. + +The default value is `true`. + +##### immutable + +Enable or disable the `immutable` directive in the `Cache-Control` response +header, defaults to `false`. If set to `true`, the `maxAge` option should +also be specified to enable caching. The `immutable` directive will prevent +supported clients from making conditional requests during the life of the +`maxAge` option to check if the file has changed. + +##### index + +By default this module will send "index.html" files in response to a request +on a directory. To disable this set `false` or to supply a new index pass a +string or an array in preferred order. + +##### lastModified + +Enable or disable `Last-Modified` header, defaults to true. Uses the file +system's last modified value. + +##### maxAge + +Provide a max-age in milliseconds for http caching, defaults to 0. This +can also be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme) +module. + +##### redirect + +Redirect to trailing "/" when the pathname is a dir. Defaults to `true`. + +##### setHeaders + +Function to set custom headers on response. Alterations to the headers need to +occur synchronously. The function is called as `fn(res, path, stat)`, where +the arguments are: + + - `res` the response object + - `path` the file path that is being sent + - `stat` the stat object of the file that is being sent + +## Examples + +### Serve files with vanilla node.js http server + +```js +var finalhandler = require('finalhandler') +var http = require('http') +var serveStatic = require('serve-static') + +// Serve up public/ftp folder +var serve = serveStatic('public/ftp', { 'index': ['index.html', 'index.htm'] }) + +// Create server +var server = http.createServer(function onRequest (req, res) { + serve(req, res, finalhandler(req, res)) +}) + +// Listen +server.listen(3000) +``` + +### Serve all files as downloads + +```js +var contentDisposition = require('content-disposition') +var finalhandler = require('finalhandler') +var http = require('http') +var serveStatic = require('serve-static') + +// Serve up public/ftp folder +var serve = serveStatic('public/ftp', { + 'index': false, + 'setHeaders': setHeaders +}) + +// Set header to force download +function setHeaders (res, path) { + res.setHeader('Content-Disposition', contentDisposition(path)) +} + +// Create server +var server = http.createServer(function onRequest (req, res) { + serve(req, res, finalhandler(req, res)) +}) + +// Listen +server.listen(3000) +``` + +### Serving using express + +#### Simple + +This is a simple example of using Express. + +```js +var express = require('express') +var serveStatic = require('serve-static') + +var app = express() + +app.use(serveStatic('public/ftp', { 'index': ['default.html', 'default.htm'] })) +app.listen(3000) +``` + +#### Multiple roots + +This example shows a simple way to search through multiple directories. +Files are look for in `public-optimized/` first, then `public/` second as +a fallback. + +```js +var express = require('express') +var path = require('path') +var serveStatic = require('serve-static') + +var app = express() + +app.use(serveStatic(path.join(__dirname, 'public-optimized'))) +app.use(serveStatic(path.join(__dirname, 'public'))) +app.listen(3000) +``` + +#### Different settings for paths + +This example shows how to set a different max age depending on the served +file type.

If the `mediaType` is invalid +or does not matches any of the `types`, then `false` is returned. Otherwise, a +string of the type that matched is returned. + +The `mediaType` argument is expected to be a +[media type](https://tools.ietf.org/html/rfc6838) string. The `types` argument +is an array of type strings. + +Each type in the `types` array can be one of the following: + +- A file extension name such as `json`. This name will be returned if matched. +- A mime type such as `application/json`. +- A mime type with a wildcard such as `*/*` or `*/json` or `application/*`. + The full mime type will be returned if matched. +- A suffix such as `+json`.

It adds a significant overhead in terms of performance and memory +consumption so we suggest to enable it only if it is really needed. + +Note that Node.js has a variety of issues with high-performance compression, +where increased concurrency, especially on Linux, can lead to [catastrophic +memory fragmentation][node-zlib-bug] and slow performance. If you intend to use +permessage-deflate in production, it is worthwhile to set up a test +representative of your workload and ensure Node.js/zlib will handle it with +acceptable performance and memory usage. + +Tuning of permessage-deflate can be done via the options defined below. You can +also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly +into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs]. + +See [the docs][ws-server-options] for more options. + +```js +import WebSocket, { WebSocketServer } from 'ws'; + +const wss = new WebSocketServer({ + port: 8080, + perMessageDeflate: { + zlibDeflateOptions: { + // See zlib defaults. + chunkSize: 1024, + memLevel: 7, + level: 3 + }, + zlibInflateOptions: { + chunkSize: 10 * 1024 + }, + // Other options settable: + clientNoContextTakeover: true, // Defaults to negotiated value. + serverNoContextTakeover: true, // Defaults to negotiated value. + serverMaxWindowBits: 10, // Defaults to negotiated value. + // Below options specified as default values. + concurrencyLimit: 10, // Limits zlib concurrency for perf. + threshold: 1024 // Size (in bytes) below which messages + // should not be compressed if context takeover is disabled. + } +}); +``` + +The client will only use the extension if it is supported and enabled on the +server. To always disable the extension on the client set the +`perMessageDeflate` option to `false`. + +```js +import WebSocket from 'ws'; + +const ws = new WebSocket('ws://www.host.com/path', { + perMessageDeflate: false +}); +``` + +## Usage examples + +### Sending and receiving text data + +```js +import WebSocket from 'ws'; + +const ws = new WebSocket('ws://www.host.com/path'); + +ws.on('open', function open() { + ws.send('something'); +}); + +ws.on('message', function incoming(message) { + console.log('received: %s', message); +}); +``` + +### Sending binary data + +```js +import WebSocket from 'ws'; + +const ws = new WebSocket('ws://www.host.com/path'); + +ws.on('open', function open() { + const array = new Float32Array(5); + + for (var i = 0; i < array.length; ++i) { + array[i] = i / 2; + } + + ws.send(array); +}); +``` + +### Simple server + +```js +import { WebSocketServer } from 'ws'; + +const wss = new WebSocketServer({ port: 8080 }); + +wss.on('connection', function connection(ws) { + ws.on('message', function incoming(message) { + console.log('received: %s', message); + }); + + ws.send('something'); +}); +``` + +### External HTTP/S server + +```js +import { createServer } from 'https'; +import { readFileSync } from 'fs'; +import { WebSocketServer } from 'ws'; + +const server = createServer({ + cert: readFileSync('/path/to/cert.pem'), + key: readFileSync('/path/to/key.pem') +}); +const wss = new WebSocketServer({ server }); + +wss.on('connection', function connection(ws) { + ws.on('message', function incoming(message) { + console.log('received: %s', message); + }); + + ws.send('something'); +}); + +server.listen(8080); +``` + +### Multiple servers sharing a single HTTP/S server + +```js +import { createServer } from 'http'; +import { parse } from 'url'; +import { WebSocketServer } from 'ws'; + +const server = createServer(); +const wss1 = new WebSocketServer({ noServer: true }); +const wss2 = new WebSocketServer({ noServer: true }); + +wss1.on('connection', function connection(ws) { + // ... +}); + +wss2.on('connection', function connection(ws) { + // ... +}); + +server.on('upgrade', function upgrade(request, socket, head) { + const { pathname } = parse(request.url); + + if (pathname === '/foo') { + wss1.handleUpgrade(request, socket, head, function done(ws) { + wss1.emit('connection', ws, request); + }); + } else if (pathname === '/bar') { + wss2.handleUpgrade(request, socket, head, function done(ws) { + wss2.emit('connection', ws, request); + }); + } else { + socket.destroy(); + } +}); + +server.listen(8080); +``` + +### Client authentication + +```js +import WebSocket from 'ws'; +import { createServer } from 'http'; + +const server = createServer(); +const wss = new WebSocketServer({ noServer: true }); + +wss.on('connection', function connection(ws, request, client) { + ws.on('message', function message(msg) { + console.log(`Received message ${msg} from user ${client}`); + }); +}); + +server.on('upgrade', function upgrade(request, socket, head) { + // This function is not defined on purpose.
