Configurable fs

[bajrangCoder]

Is there any way to configure any type of fs client to isomorphic-git?

As in my case I have to use cordova-plugin-file for fs stuffs but isomorphic-git only supports nodejs like fs only(i guess)

I have to integrate isomorphic-git for git client in this app and here is it's fs which uses cordova file , sdcard plugin etc.

Any solution will be appreciated 🤗

I think the easiest way is to look at lightningFS library that implements fs module that can be used in web browser.
But to have custom fs you need to implement custom backend.

Ok Thanks for your response!
Can I get some hints or any sample of implementing custom backed? As on lightningFS library only mention about backend but there is no any docs or example about it

[jcubic]

There is information in README: Providing a custom backend (advanced usage). The sad thing is that the custom backend is almost like an entirely new implementation of fs.

I've added a way to swap Key/Value pair (db option) in lightning-fs, and was always wondering what is the point of custom backend if it's like your own lightning-fs library.

I have seen it but how I will pass my custom IBackend as it mentioned in readme that I will need to pass on option backend option but there is no any backend option in option interface

The sad thing is that the custom backend is almost like an entirely new implementation of fs.

Yes it's totally like having a own fs

It seems there is an option backend:

https://github.com/isomorphic-git/lightning-fs/blob/main/src/PromisifiedFS.js#L82C29-L82C36

But it's not in TypeScript definition. If you don't use TypeScript you can try it. And if you use TypeScript maybe you will need to put as any somewhere.

Yeah there are some issues in lightning fs typings declaration file as it makes db option required. For now I have modified it and tested fs.promises.readdir()and it's worked after doing some bypassings.

And I want to ask that how can I overide the default function that disturb the filepath as in my case when I pass these type of paths : content://com.externalstorage....../ then lighting fs convert this path to this : ./content:/com......
As it will be needed in any case for my use case it's not required

Also noticed one error that occurs when ever I start my app but it doesn't the affect any thing , here is the screenshot of error:

Note
I initialise the lighting fs in constructor like this 👇

constructor() {
  const customBackend = new FsBackend();
  this.fs = new FS();
  this.fs.promises.init("myfs", { backend: customBackend });
}

[jcubic]

Don't call the init function it's an internal method.

[bajrangCoder]

Ok but what about this one 👇

Edit: I have used like this but still same error:

this.fs = new FS("myfs", { backend: customBackend });

[jcubic]

I think that it will be much simpler to just implement your own fs and all the methods that are required. But if you would like to use lightning-fs you will need to fork it and modify to not normalize the path (or whatever function it used for paths).

Ok
