@philipp-strack,

You can use the Origin Private File System (OPFS) using the FileSystemAccess backend:

import { configure, fs } from '@browserfs/core';
import { FileSystemAccess } from '@browserfs/dom';

await configure({ backend: FileSystemAccess, handle: await navigator.storage.getDirectory() });

// usage example
if(!(await fs.promises.exists('/myfile'))) {
	await fs.promises.writeFile('myfile', 'this will persist in the OPFS'); // PWD is /
}

const contents = await fs.promises.readFile('/myfile', 'utf-8');

console.log(contents);

Important

FileSystemAccess is an asynchronous backend. You can not use synchronous functions (e.g. readFileSync) unless you first wrap it in an AsyncMirror.

@philipp-strack,

Of course!

I made a mistake in my original code but I fixed it in an edit, so please use the edited code (I assigned the handle to backend, which was not correct)
