ZenFS DOM Backends

ZenFS backends for DOM APIs. DOM APIs are only available natively in browsers.

[!IMPORTANT] Please read the ZenFS core documentation!

Backends

• WebStorage: Stores files in a Storage object, like localStorage and sessionStorage.
• IndexedDB: Stores files into an IndexedDB object database.
• WebAccess: Store files using the File System Access API.

For more information, see the API documentation.

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 { WebStorage } from '@zenfs/dom';

await configureSingle({ backend: WebStorage, storage: localStorage });

if (!fs.existsSync('/test.txt')) {
    fs.writeFileSync('/test.txt', 'This will persist across reloads!');
}

const contents = fs.readFileSync('/test.txt', 'utf-8');
console.log(contents);
