LongPollingChat

This node.js LongpollingChat is used to demonstrate one possible deployment pipeline.

Technology

The Node.JS application starts a server which also servers an User interface to use the chat.

• User Interface: http://[path-to-app]/

It uses the NPM package manager to define the dependencies.

UnitTests

UnitTests are written in NodeUnit.

The nodeunit module was added as git submodule. To install it locally, use the following commands

git submodule init
git submodule update

Now you can run the tests using:

./node_modules/bin/nodeunit chat/test/server

Setup of your local environment

To run the app locally, you can either use the foreman server (built-in in Heroku) on the app root:

git clone https://github.com/anotherSasFeld/deploymentExample
foreman start

Otherwise, install the following:

1. Install node.js including the npm packaging manager
2. git clone https://github.com/anotherSasFeld/deploymentExample
3. Add a new environment for your testing environment in config/environment.json
4. Set the NODE_ENV environment variable to the name of your testing environment configured in 3.
5. For unittests, see "UnitTests" section.
6. Start the app using:

node chat/server/LongPollingChat.js

Continous Integration on Travis

• You can find the build overview on: https://travis-ci.org/anotherSasFeld/deploymentExample
• The current installation is very simple: "npm install nodeunit -g"

Production system

The app will be deployed to Heroku.

• URL to the Live App: http://peaceful-stream-4615.herokuapp.com
• Correct NODE_ENV Setting: 'heroku' (set via heroku config:set NODE_ENV=heroku)
