Universal js library for reading/writing files.
https://web.dev/storage-for-the-web/
In node, it uses the fs package to read/write.
The default behavior of the implementation uses the best option available to the browser. The order of preference is as follows:
- File and Entries API
- IndexedDB
- LocalStorage
Both IndexedDB and the Cache API both throw a DOMError named QuotaExceededError when you've exceeded the quota available.
The following web API was chosen to support a generic browser FileSystem.
| Feature | Firefox | Chrome | Edge | Safari | IE |
|---|---|---|---|---|---|
| IndexedDB | yes | yes | yes | yes | no |
The following APIs were all considered in choosing a backend to support
| Rejected APIs | Reason |
|---|---|
| File and Entries API | Requires permission for each request |
| Cache | Requires a request URL |
| SessionStorage | Limited storage |
| LocalStorage | Limited storage |
| Cookies | really? |
| File System Access API | Chromium only |
| WebSQL | deprecated |
| Application Cache | deprecated |
