Platina NPM | npm.io

Platina

Platina is an advanced in-memory file system, closely resembling the NodeJS FileSystem API. Platina is ideal for use in your test suites and for applications requiring a virtual file system, such as compilers and asset bundlers.

npm i --save platina

Features

JSFS-compatible API
Synchronous and asynchronous operations using promises
Growing number of NodeJS FileSystem API methods supported
Efficient writes and reads of unpredictably sized data
Fully working in a browser environment

API

import Platina from "platina"

const fs = new Platina()

// now do whatever what you'd do with a normal `fs` object

fs.writeFileSync('/test.txt', 'some content ...')

// ...

Refer to the official NodeJS FileSystem docs for the full documentation of the methods you can use. Should you find anything that does not comply with the official docs, please file an issue.

JSFS

Just as fs-extra, Platina fully integrates with JSFS, making it possible to create isolated file systems and more.

import Platina from "platina"
import isolate from "jsfs/isolate"

const fs = new Platina()
fs.mkdirSync('/foo')

newfs = isolate(fs, '/foo')

newfs.writeFileSync('/test.txt', 'foo bar baz') // will write to /foo/test.txt
