The offline-editor-js projects includes but is not limited to the following dependencies:
- localStorage. The limits vary by browser and is typically 5MBs per domain name. For additional information see W3C's webstorage specification, Section 5.
- indexedDB. Storage limits for indexedDB are not necessarily consistent across browsers. It's generally understood to be 50MB. Here is a Mozilla document discussing limits across different browsers.
- Advanced users of the library should be aware that JavaScript stores some strings as UTF-16. More information can be found in this Mozilla article.
- If a user completely flushes their browser cache all queued edits, tiles as well as anything stored in local storage, IndexedDB, SQLite or even the appcache will most likely be lost.
- Data stored by the library should persist if the browser is shutdown and restarted. However, this does not mean that your application will be returned to its correct state. A client web application's state has to be programmatically managed. This includes the state of items including but not limited to feature layers within your application.
- Browser support for all the functionality in this library isn't gauranteed, of course.
