Capacitor Filesystem

[ak1dos]

I added electron to my capacitor project, I'm having problems with the Filesystem plugin. I downloaded some pdf files and saved with the method

let result = await Filesystem.writeFile ({
  path: path,
  data: fileData,
  directory: FilesystemDirectory.Data
})

my problem is being able to show them to electron api. if I try to fetch the uri of the saved file I see it with the Filesystem plugin, but I don't understand where it is saved or how to use it with electron.

let result = await Filesystem.getUri ({
  path: pathFile,
  directory: FilesystemDirectory.Data
});

console.log (result.uri) /DATA/example.pdf

What does it mean, that this has been set to "plugin update needed"? Is there any plan for solving this? Any idea regarding the timeline? My project is blocked by this issue.

Any news here? We cannot expect to use electron without a Filesystem access ...

@IT-MikeS Couldnt we add it from here: https://github.com/ionic-team/capacitor/tree/2.x/electron/src/electron directly to @capacitor-community/electron sources?

Or should I create a @capacitor-community/filesystem plugin which just implements it for electron? What is the best approach here?

After 4 is released the official file system plug-in for capacitor will need a pr giving it electron support.

At this point you can either create your own plugin or expose your own file api using electrons context bridge system for use in the renderer processes

@IT-MikeS thanks for the reply. I am currently trying to create my own plugin implementing the Filesystem API.

So far I kinda got it working but am running into an issue where the Promises of the plugin are never resolved. I do not know why this is the case as my other plugins do not have this issue (edit: my other plugins now also have this issue ...):

https://github.com/digaus/capacitor-community-filesystem

The calls are working (folders and files get created when using mkdir or writeFile) but they are never resolved or rejected.

When the Plugin is supposed to reject, I get following error;

Terminal:

args
[ { path: 'files', directory: 'DOCUMENTS', recursive: false } ]

[Function: mkdir]
isPromise

Any idea whats the issue here?

What version of the platform are you using out of curiosity?

I added a pull-request to the default Capacitor plugins repo that adds support for Electron to the Filesystem plugin: https://github.com/ionic-team/capacitor-plugins/pull/792
