@jsonjoy.com/fs-node

In-memory filesystem with Node.js fs-compatible API.

Installation

npm install @jsonjoy.com/fs-node

Usage

import { Volume } from '@jsonjoy.com/fs-node';

const vol = new Volume();
vol.writeFileSync('/hello.txt', 'Hello, World!');
console.log(vol.readFileSync('/hello.txt', 'utf8')); // Hello, World!

Create filesystem from JSON

import { Volume } from '@jsonjoy.com/fs-node';

const vol = Volume.fromJSON({
  '/app/index.js': 'console.log("Hello");',
  '/app/package.json': '{"name": "app"}',
});

console.log(vol.readdirSync('/app')); // ['index.js', 'package.json']

API

The Volume class implements Node.js fs module's synchronous and callback APIs:

• readFile, readFileSync
• writeFile, writeFileSync
• mkdir, mkdirSync
• readdir, readdirSync
• stat, statSync
• unlink, unlinkSync
• ... and many more

It also exposes a promises property for the Promise-based API:

const data = await vol.promises.readFile('/hello.txt', 'utf8');
