Real-time web-based collaborative coding

Features

  • Syntax highlighting code editor (using Ace)
  • Live edit merging via operational transforms
  • Load files from GitHub repositories and save changes as a patch
  • Audio and video through WebRTC

Design overview

Pairjam is separated into client and server components.

The client consists solely of static files, which means it can be served quickly and cheaply on a CDN (pairjam.com assets are hosted on GitHub pages). The client uses WebSockets for communication, WebRTC for peer-to-peer audio / video, and React.js.

The server is a Node.js WebSocket server that can run on one or more separate machines.

Running your own

Setup

To get Pairjam running on your local machine, first clone the repository

git clone https://github.com/neerajwahi/pairjam.git

Next, install npm dependencies

cd server && npm install
cd ../client && npm install

To integrate the server with GitHub, a GitHub API public key and secret are needed. These should be placed in the GITHUB_CLIENT_ID and GITHUB_CLIENT_SECRET environment variables before running the node server.

If the server does not find these env variables upon loading, rate requests will be limited to GitHub's unauthenticated limit.

Running locally

Once setup has been completed, run the WebSocket server:

cd ../server && node app.js

Then in a new tab, serve the static files from the client/public directory:

cd ../client/public && python -m SimpleHTTPServer 8000

Hosted

Instructions coming soon!

Building Pairjam

Pairjam uses gulp.js for its build system.

Client

If you're working on the client, run

cd /path/to/client
gulp && gulp watch

This will build the app and watch any .jsx or .scss files for changes.

Server

The server won't reflect your changes until you re-run it. To watch the server and re-run it automatically try nodemon.
