MEAN stands for MongoDB , ExpressJS, AngularJS, NodeJs. MEAN is an opinionated fullstack javascript framework - which simplifies and accelerates web application development.

Very first you have to setup local environment with MongoDB and NodeJS. Please check and install NodeJS from www.nodejs.org.

Install MongoDB on your local machine. Due to install MongoDB and NodeJS you’ll need to install HomeBrew first.

Install homebrew

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

Install Node.js by brew

$ brew install

Now this is the time to install MongoDB To install the MongoDB binaries, issue the following command in a system shell:

brew update

brew install mongodb

To build MongoDB from the source files and include SSL support, issue the following from a system shell:

brew install mongodb --with-openssl

To install the latest development release for use in testing and development, issue the following command in a system shell:

brew install mongodb --devel

Now we’re ready to install MEAN app on your local machine.

To install MEAN app scaffold

$sudo npm install -g meanio

Now you can initiliaze your MEAN app

$ mean init myApp

MEAN Package install & uninstall

$ mean install package-name

Available packages - mean-admin - tokens - translate - ga (Google Analytics) - upload - socket - gmap - comments - crop

usage example

$ mean install mean-admin

Uninstall package

$ mean uninstall package-name

Delete package

$ mean -d package-name

NOTE: Run Grunt service after your changes to compile your script.

$ grunt serve

#Setup Heroku Account

In order to work with Heroku, you also need to download Heroku’s toolbelt (https://toolbelt.heroku.com) which will give you the needed command line tools to communicate with Heroku’s backend. Right after registering in Heroku and installing it’s toolbelt, run the following command and add your SSH key, to identify yourself with Heroku:

$ heroku login

You’ll need your email address and password for Heroku. Before you push your repo, you need to add public key into your heroku.

Generate the RSA key first by following

$ ssh-keygen -t rsa

Add your key to heroku

$ heroku keys:add

Read more about SSH key https://devcenter.heroku.com/articles/keys

Before you go further let’s setup your database on Heroku.

Login to your Heroku dashboard goto Add-ons tab and find MongoHQ under Data Stores. Select free plan and add to your package. Now go to your apps. Select MongoHQ from your app list.

Goto Admin tab (on the left side) and select Users tab on top of the panel. From here you can setup your MongoDM access by adding a user.

Copy your Mongo URI

mongodb://<user>:<password>@linus.mongohq.com:XXXX/appXXXXXXX

$ heroku create myApp

Now you’re ready to push your code into your Heroku

#Setup your MEAN App config

Very first you have to setup your MongoDB on your config to run your scaffold app.

go to /yourApp/config/env/development.js

find mongodb:localhost

replace with your MongoURI

#Prepare to push Heroku

$ git init
$ git add .
$ git commit -a -m "Fresh start"

Now this is a time to push it

$ git push heroku master

Now you can see your project http://yourApp.herokuapp.com

Enjoy playing around
