KOAN Stack is a boilerplate that provides a nice starting point for full stack JavaScript Web development with Koa, AngularJS, and Node.js along with MongoDB and WebSockets. A summary of tech stack:

• Client: AngularJS and Twitter Bootstrap with pure html partials (no server side rendering so it's fully static and CDN ready). Bower packages are located at client\bower_packages.
• Server: Koa for RESTful API serving on Node.js.
• WebSockets along with JSON-RPC is used for real-time client-server communication and browser sync.
• OAuth 2 is used for social authentications. Instead of auth cookies, we use JWT along with HTML5 local storage.
• Grunt tasks are used to facilitate development and testing.
• MongoDB for persistence.

Live Example

Browse the live KOAN example on https://koan.herokuapp.com which is a Facebook like real-time sharing app.

Getting Started

Make sure that you have Node.js v0.12 or higher, and MongoDB v2 or higher (running on the default port 27017) installed on your computer. To get started with KOAN stack, do following:

git clone --depth 1 https://github.com/soygul/koan.git
cd koan
npm install
npm start

Your application should run on the 3000 port so in your browser just go to http://localhost:3000. If you want to run tests, simply type:

npm test

Configuration

All configuration is specified in the /server/config directory, particularly the config.js file. Here you can hook up any social app keys if you want integration with Twitter, Facebook, or Google.

Heroku Deployment

Before you start make sure you have heroku toolbelt installed.

git init
git add .
git commit -m "initial version"
heroku apps:create
heroku addons:add mongohq
heroku config:add NODE_ENV=production
git push heroku master
heroku open

Optionally, you can pass credentials to KOAN via environment variables as it might not be secure to store them in your repo. Note that if you do this, you'll need to adjust other configuration options accordingly (i.e. FB/Google client IDs, etc.).

heroku config:add SECRET=jwt_secret PASS=login_pass FACEBOOK_SECRET=facebook_oauth_secret GOOGLE_SECRET=google_oauth_secret

Testing

You can run all the tests with npm test. Tests are run with:

• Client (unit): Jasmine + Karma (Angular default)
• Client (e2e): Jasmine + Protractor (Angular default)
• Server: Mocha/SuperTest/Should (Koa default)

Server tests utilize co so you can use */yield expressions while writing tests. See /test/server/users.js as an example.

Credits

Client side is entirely based on the official: Angular Seed. Server side simply utilizes generally accepted Koa middleware and Node.js best practices.

The Name

The project name is an acronym for Koa, Angular, and Node. It also is the name for a Zen Buddhist riddle used to focus the mind during meditation and to develop intuitive thinking.
