Build Modern MEAN Stack Web App

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

The main reason for choosing the MEAN stack over others is because of the use of a common language for both client-side and server-side. Since, all these technologies are written in JavaScript, your web development process becomes neat. Node.js is a platform that brought JavaScript implementation on the server-side. With Angular  using JavaScript on the front-end, it becomes easier to reuse code from back-end to front-end.

MEAN stack offers a modern approach to web development. It also makes use of the power of modern SPAs (single-page applications), which does not require entirely refreshing a web page for every server request like most traditional web applications do. Today there is a trend to develop multiple frameworks that correspond to a single programming language and form a full-stack solution. But, as of now, using MEAN stack is a very effective approach to web development.

In this course, we are going to build our backend application Nest.js. Nest.js is a Node.js framework. It is built on the top of Express and Typescript.

Nest.js is a progressive Node.js framework for building efficient, reliable and scalable server-side applications. NestJS is a server-side (backend) application framework beautifully crafted to support developers productivity and make their lives happier. Well, it’s not only a framework, it’s an enabler of entering the world of advanced engineering concepts such as Domain Driven Design, Event Sourcing, Microservices architecture.

I spent a good few years in my career developing large scale apps and it didn’t let me down any single time. It’s well written, having quality as an objective, modular web framework with a good documentation, delivering nice developer experience. Exactly the same way I’d describe Nest.

NestJs is built on the top of Typescript and Express.js. It also combines some elements of Object Oriented Programming and functional programming.

Here comes NestJS, a framework which is fully written in TypeScript (it supports JS too, but types are good), it’s easily testable and brings in all the necessary stuff you always think about but you don’t know what to choose.

Why NestJs?

NestJS doesn’t try to limit you to a particular way of doing things, it just provides the tooling you need. It doesn’t try to reinvent the wheel, it utilize existing tools you already know. For example, it uses express behind the scenes which makes your app compatible with the majority of express middlewares.

Here are some good reasons why NestJS shines:

• Dependency Injection— NestJS provides DI straight out of the box, increasing efficiency, modularity and testability of applications.

• Modularisation — NestJS provides a modular structure for organizing code within the same domain boundary into separate modules.

• Flexibility — NestJS provides structure, which helps large teams build complex applications and yet comes in as lightweight as possible, so how you want to build is your choice.

• Familiar APIs you already know — NestJS is heavily inspired by Angular, it is also quite similar to much established frameworks like Spring and .NET. This provides a shorter learning curve and lower entry threshold for developers.

• Community — NestJS is the fastest rising framework, already with 14K stars surpassing HapiJS. Also, with NestJS leveraging on the Angular way of doing things, things can only get better for the community.

In this course, I will teach you the foundations/fundamentals of NestJs. I will teach you how to build RESTFUL APIs step by step. You will also learn how to plan, design and deploy APIs. I have also another separate section of GraphQL.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
