Filesystem improvements

[joel-daros]

• The FileWriteOptions directory property needs to accept string concatenations like FilesystemDirectory.ExternalStorage + '/downlad', not only types defined in Enum.

• Will be useful If the The FileWriteOptions directory accepts Blob type not only strings.

• When you write a file, if it already exists, it will be overwritten? Is there any parameter for this?

👍 Using Blobs for file read/writes would be really useful.

Hello, are there any plans to implement any of the improvements suggested above?

[oliverandersencox]

@jcesarmobile is there any progress with saving as a blob? If not, what would you recommend is the best approach to store blob data?

Would be a good one to look at after 1.0 to improve filesystem performance, along with #1392 and #1391

Also feeling pretty limited without Blob writability currently.
Is the best option to just fall back to cordova-plugin-file for that usage for now?

Sharing my workaround with you.

I'm using web-implementation of the Filesystem plugin.
Don't know if it's a good solution but it helps solving my problem.

import { FilesystemDirectory, FilesystemEncoding } from '@capacitor/core'
// const { Filesystem } = Plugins // => Doesn't work with blob in native
// Workaround: Use Web-Implementation of plugin
import { FilesystemPluginWeb } from '@capacitor/core/dist/esm/web/filesystem.js'
const Filesystem = new FilesystemPluginWeb()

Any news on blob support?

If anyone still needs this, I implemented a solution myself which works with current cap version. Here is a sample app:

https://github.com/digaus/CapacitorSaveBlob

Tested myself in browser, android and on iOS.

Maybe @jcesarmobile or someone else is willing to integrate this into the current filesystem plugin (maybe add a new encoding type blob) if this solution is up to their standard 😄

Edit: with this PR it will also work for electron -> #2567
