What do you think is the correct solution to problem?

• Drop Node.js support outside of LTE
• Drop uri-js (which depends on punycode)

Will you be able to implement it?

Yes

Related issues:

• punycode is deprecated, remove dependency garycourt/uri-js#94

Note:

• My understanding is that the only reason for uri-js is backwards compatibility for older Node.js versions.

Also happens in newer version
"ajv": "^8.12.0"
#2350

I've opened a PR to fix this in uri-js, the package ajv depends on here: garycourt/uri-js#95

[iwasrobbed]

uri-js is no longer being maintained, so there's not a great chance of it being fixed upstream.

You can also nvm install 20 && nvm use 20 to go back to Node v20.11.1 and silence it for now until ajv/eslint/etc update their dependencies

Hi there,
I created a replacement for library uri-js as temporal solution.

• Based on Node.js and browser URL api
• 99% compatible with original URI.js library
• Solves "The punycode module is deprecated" warning in Node
• Tested with libraries: ESLint, Webpack, Ajv (runned all Ajv tests)

You can add to package.json of your project:

"overrides": {
    "uri-js": "npm:uri-js-replace"
 }

how progress of this?

[Symmettry]

seems this exists: https://www.npmjs.com/package/toad-uri-js

can this be done? it's really annoying to see when using eslint.

alternativel,y andreinwald's one can be used. i just found this asweel

[jasoniangreen]

We're working on moving to fast-uri, just waiting for some compatibility fixes on their side so will close this as it is redundant with ongoing work.

[bngo97]

what's the progress on this? @jasoniangreen Is there another issue we can follow to know the progress?

[Mon-ius]

do we have any progress? 🤗

[jonascarlbaum]

Using eslint that is dependent on ajv and I get alot of these deprecation warnings — which is really annoying.

Really looking forward for this to be solved...

Release v8.17.1 has removed uri-js

[johnholliday]

As indicated by @jasoniangreen, version 8.17.1 of ajv is no longer dependent on punycode. If you're using eslint, you can add the following to your package.json.

// pnpm

{
  "pnpm": {
    "overrides": {
      "ajv": "8.17.1"
    }
  }
}

// terminal
pnpm install

This will force eslint to use the newer version of "ajv".

[jonascarlbaum]

So, guess that means that for yarn 4.5+ I need to do?

{
  "resolutions": {
    "ajv": "8.17.1"
  }
}

will try it out soon…
