MEAN Stack User Registration and Login Example & Procedure:

The term MEAN stack refers to a collection of JavaScript based technologies used to develop web applications. MEAN is an acronym for MongoDB, ExpressJS, AngularJS and Node.js. From client to server to database, MEAN is full stackJavaScript.

Node.js is a server-side JavaScript execution environment. It’s a platform built on Google Chrome’s V8 JavaScript runtime. It helps in building highly scalable and concurrent applications rapidly.
Express is lightweight framework used to build web applications in Node. It provides a number of robust features for building single and multi-page web application. 
MongoDB is a schemaless NoSQL database system. MongoDB saves data in binary JSON format which makes it easier to pass data between client and server.
AngularJS is a JavaScript framework developed by Google. It provides some awesome features like the two-way data binding. It’s a complete solution for rapid and awesome front end development.
In this article, we’ll be creating a simple login and registration application using the MEAN stack. So, let’s dive in.
How to implement MEAN App: 
To Follow the below steps you can easily know how to implement Mean app in your local.
Step 1: MEAN Stack Dependencies: To run MEAN stack applications downloaded locally you need NodeJS installed and MongoDB running.
Step 2: Get the latest code from here  Download source code 
Step 3: Once you've downloaded the code you can run the command 'npm install' from the project root folder (where the package.json file is located) to download all node package dependencies.
Step 4: Then run 'node server.js' from the same location to start the web server 
Step 5:  Now you can browse http://localhost:3000 to access the application.
