Fundamentals of MEAN stack




In this blog-post, we will learn about the fundamentals of mean stack to build a real-world application.

What can you expect from this post?

·       We will take you through the fundamentals of JavaScript so that you feel at ease with Mean concepts.
·       How to begin with the mean stack.
·       To Understand the main components to build applications using Mean Stack.
·       To start your work with Mean stack and JavaScript.
·       Detailed video and course tutorials.

What is the MEAN stack?
Mean is a short form of all the commonly used technologies. The cool thing about Mean stack is 
whether server-side or client-side, we have only one language to learn JavaScript and can use 
on both sides.We build a simple application by writing easy and little code using all the key 
components.

Key components of MEAN stack are

Mongo DB (Database)
AngularJS (Client-Side)
Node.JS (Application Server)
Express (Framework)





Mongo DB  Stores the application's data, both the application and database use JavaScript.In Mongo DB you can add fields to the database without reloading the entire table. Mongo DB is widely known for its ability to manage large data.

Express It’s a web application framework for Node.JS.Express handles communication between the frontend and the database.it helps and ensures easy and smooth transfer of data to the end-user. Express helps excellent error handling and templating to aid your development.

Angular JS Popular frontend framework. It helps in the front end development and commonly we use Angular JS when we develop web applications in JavaScript. Angular JS is used in both desktop and mobile Applications. It has easy to use template features which makes it ideal for cloud-based applications.

Node.JS It is an ideal framework for cloud-based applications, it can be easily scalable as per demand.Node.JS is the most important part of the MEAN stack. It comes with web server and easy to deploy Mongo DB databases and applications to the cloud.


  
Prerequisites for MEAN

·       Basic knowledge of HTML
·       JavaScript concepts
·       Functions
·       Expressions
·       Variables & scope
·       Objects

Before getting started we need to install Node.JS and then install Mongo DB .below video has all the instructions to set up Mongo on different operating systems.

Installation



After following the installation of Express which is used to communicate 
between frontend and database, we begin installing a database MongoDB






Benefits of using Mean Stack

·       We have to learn only one language JavaScript to develop the whole application.
·       Learning curve is easy.
·       Database is document-oriented.
·       We have Node.js on the server-side which is fast and scalable
·       Angular JS on the client-side ensures reusable maintainable client-side applications and used to create single-page applications with much ease.
·       Data transfer is also done in JSON format which is again supported by JavaScript.


To get started first, we have to learn what is JavaScript?

JavaScript is a programming language built into the browser and is focused primarily on making the pages interactive
Previously JavaScript was used as a client side but with the time and its gaining popularity it is one of the most widely used programming language.
Now it’s also available as a server-side language in the form of Node.JS.
