ZenFS iso Backend

ZenFS backend for iso files.

[!IMPORTANT] Please read the ZenFS core documentation!

Backend

This package adds the Iso backend, which allows you to create a readonly file system from a .iso file.

For more information, see the API documentation.

Installing

npm install @zenfs/iso

Usage

[!NOTE] The examples are written in ESM.
For CJS, you can require the package.
If using a browser environment, you can use a <script> with type=module (you may need to use import maps)

import { configure, fs } from '@zenfs/core';
import { Iso } from '@zenfs/iso';

const res = await fetch('http://example.com/image.iso');

await configure({
    mounts: {
        '/mnt/iso': { backend: Iso, data: new Uint8Array(await res.arrayBuffer()) },
    },
});

const contents = fs.readFileSync('/mnt/iso/in-image.txt', 'utf-8');
console.log(contents);
