angular2-socketio-chat-example
An example Angular 2 chat app, made on top of ExpressJS & Socket.io.
NOTE! The app currently is tested only to work with Angular 2 RC2. It should work at least with RC4 without any significant changes, however, with RC5 and RC6 there would be greater need of refactoring.
Prequisities
The projects needs that you have the following things installed:
- NodeJS (version 5 or greater, tested with 6.3.1)
- MongoDB (tested with version 3.2.6)
- Heroku Toolbelt (latest)
All of the prequisities are available on Linux, Windows and Mac OS X systems with their own installers (just go to links above and download package).
Installing prequisities on Mac OS X
You might wish to install the prequisities with Homebrew, so here're quick guide to do that.
Install Homebrew
You can install Homebrew with this command:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
NodeJS
You can install NodeJS simply by giving command:
brew install node
Node Version Manager (recommended)
If you wish to run multiple NodeJS versions (to avoid problems with old NodeJS modules, you might want to use 4.2 as default, and NodeJS 5 on newer projects and even try NodeJS 6), you should install NVM (Node Version Manager) for managing multiple NodeJS versions.
NVM can be installed by the following command:
brew install nvm
Note! Follow the instructions after installing NVM, so that you'll get the shell extended (basically adding stuff to your .bash_profile).
Then you can just install and use specific NodeJS version like:
nvm install v6.3.1
nvm use v6.3.1
nvm alias default v6.3.1
MongoDB
brew install mongodb
ln -sf /usr/local/opt/mongodb/homebrew.mxcl.mongodb.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
Note! You can also unload with launchctl, as well as add the load/unload commands to your .bash_profile or equivalent as aliases.
Installation
Install node modules
npm install
Note! Typings are automatically installed along with the npm install.
Install typings globally (optional)
If you wish to add more typings easily you can install typings npm package globally with the following command:
npm install -g typings
After that you can install more typings for packages with typings install <package> --save or with --global or global (formerly ambient typings).
Local development
Build
npm run build
Start web server
npm start
Gulp (optional)
The gulp tasks for this project require gulp v4-alpha. If you don't wish to globally install the v4 gulp-cli, you can run the gulp tasks using the locally installed gulp under ./node_modules/.bin — for example:
./node_modules/.bin/gulp
If you wish, you can also install Gulp globally:
npm install -g gulpjs/gulp-cli#4.0
After that you can just run:
gulp

Heroku
Create a Heroku app first (if you don't have already one)
heroku create --region eu
Add MongoDB
You can use a free plan of MongoLab for data storage:
heroku addons:create mongolab:sandbox
Deploy
git push heroku origin
Open Heroku app in browser
heroku open
