Companion

Uppy logo — a superman puppy in a pink suit

Build Status

Companion is a server integration for Uppy file uploader.

It handles the server-to-server communication between your server and file storage providers such as Google Drive, Dropbox, Instagram, etc. Companion is not a target to upload files to. For this, use a https://tus.io server (if you want resumable) or your existing Apache/Nginx server (if you dont). See here for full documentation

Install

npm install @uppy/companion

If you dont have a Node.js project with a package.json you might want to install/run Companion globally like so: [sudo] npm install -g @uppy/companion@1.x (best check the actual latest version, and use that, so (re)installs are reproducible, and upgrades intentional).

Usage

companion may either be used as pluggable express app, which you plug to your existing server, or it may also be run as a standalone server:

Plug to an existing server

import express from 'express'
import bodyParser from 'body-parser'
import session from 'express-session'
import companion from '@uppy/companion'

const app = express()
app.use(bodyParser.json())
app.use(session({ secret: 'some secrety secret' }))
// ...
// be sure to place this anywhere after app.use(bodyParser.json()) and app.use(session({...})
const options = {
  providerOptions: {
    drive: {
      key: 'GOOGLE_KEY',
      secret: 'GOOGLE_SECRET',
    },
  },
  server: {
    host: 'localhost:3020',
    protocol: 'http',
  },
  filePath: '/path/to/folder/',
}

const { app: companionApp } = companion.app(options)
app.use(companionApp)

To enable companion socket for realtime feed to the client while upload is going on, you call the socket method like so.

// ...
const server = app.listen(PORT)

companion.socket(server)

Run as standalone server

Please make sure that the required env variables are set before runnning/using companion as a standalone server. See.

$ companion

If you cloned the repo from GitHub and want to run it as a standalone server, you may also run the following command from within its directory

npm start

Companion can also be deployed to Heroku
