An example chat application made with Angular and Socket.io (and NodeJS, ExpressJS and MongoDB).
- Angular 4.1.1 or later
- Webpack 2.5.1 or later
- TypeScript 2.3.2 or later
- Styles with SCSS
- Full stack compilation on Heroku build process
The projects needs that you have the following things installed:
- NodeJS (version 7 or greater, tested with v7.10.0)
- MongoDB (tested with version 3.4.2)
- Heroku Cli (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).
You might wish to install the prequisities with Homebrew, so here're quick guide to do that.
You can install Homebrew with this command:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
You can install NodeJS simply by giving command:
brew install node
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 6 on newer projects, 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 v7
nvm use v7
Note! This project is tested currently with NodeJS v7.10.0.
brew install heroku-cli
brew install mongodb
ln -sf /usr/local/opt/mongodb/homebrew.mxcl.mongodb.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
brew install redis
ln -sf /usr/local/opt/redis/homebrew.mxcl.redis.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
You should install installer packages of NodeJS, MongoDB and Heroku Toolbelt, either 32bit or 64bit depending on your system.
When MongoDB is installed, you should create (or ensure) that you have C:\Data -directory created:
dir C:\Data
After ensuring or creating the directory, you can just launch MongoDB from command line:
mongod.exe
You could use Microsoft's port of Redis, which provides an easy to use installer.
On Windows installations, it will ease the task if you use PowerShell and add all the necessary paths to utilities to Windows environment path. To do so, you can right-click the Start -button, select Advanced System Settings and finally select Environment Variables. You need to restart the PowerShell (or possibly logout and login) to get the environment variables going.
npm install
Note! Type definitions were earlier installed with typings, however, due switching to TypeScript 2.0 the type definitions are managed with npm and more specifically @types/*** name space.
npm run build
npm start
npm run dev
This runs Webpack in watch mode, which updates both client and server assets. Server is loaded automatically, client needs manual refreshing. TBD: HMR or livereloading.
MONGODB_URI=mongodb://user:pass@hostname:port/databaseMongoDB URI (you can leave empty if you use MongoDB on localhost)
For local development, you can save the environment to .env -file on project root:
MONGODB_URI=mongodb://user:pass@hostname:port/database
heroku create --region eu mycoolapp
You can use a free plan of MongoLab for data storage:
heroku addons:create mongolab:sandbox
You can use a free plan of Heroku Redis for fast memory cache.
heroku addons:create heroku-redis:hobby-dev
git push heroku master
heroku open
