hook.io-vfs

UNRELEASED / WIP

Node.js module that powers the hook.io platform's Virtual Filesystem.

Introduction

This module is the component which hook.io uses to allow users to manage remote cloud files across many adapters using a familiar local filesystem based API.

You are encouraged to use this module as-is, or modify it to suite your needs. If you are interested in contributing please let us know!

Features

• Provides a Virtual Filesystem for all major cloud storage providers
  • Amazon S3
  • Google Cloud Files
  • Azure Cloud Files
  • Rackspace Cloud Files
  • Any SSH / SFTP server!
• Provides unified filesystem API which maps one-to-one with Node.js core fs module
  • Can be used as drop-in replacement for require('fs') module
  • Use familiar methods like readFile, writeFile, createReadStream, createWriteStream
  • Provides additional Vinyl Virtual File representation files

Example

var vfs = require('hook.io-vfs');

var client = vfs.createClient({
  google: {
    adapter: "google",
    keyFilename: '/path/to/google.json', // path to a google JSON key file
    projectId: 'my-project'
  }
});

client.writeFile('hello.txt', 'i am a file!', function (err, vinyl){
  console.log(err, vinyl);
  //  "vinyl" contains representation of file ( stats / metadata ) 
});

client.readFile('hello.txt', function (err, file, vinyl){
  console.log(err, file, vinyl);
  // "file" is Buffer of file contents ( same as Node.js `fs.readFile` )
  // "vinyl" is a https://github.com/gulpjs/vinyl object
});

client.readdir('.', function (err, dir, vinyl){
  console.log(err, dir, vinyl);
  // "dir" is array of file names ( same as Node.js `fs.readdir` )
  // "vinyl" is an array of https://github.com/gulpjs/vinyl objects
})

see: config/index.js property config.adapters for additional adapter / provider options

API

Uploading / Downloading Files

Callback Style

vfs.upload(path, contents, cb);

vfs.download(path, cb);

Stream Interface

var writeStream = vfs.upload(path, contents);

var readStream = vfs.download(path, contents);

All other fs operations

Each adapter does it's best to map one-to-one with the Node.js core fs module API interface.
