Master the MEAN stack and its components to create dynamic web applications.

Become a MEAN Stack Developer

In this module, we'll learn how to build a full-stack application using the MEAN stack. We'll begin with the frontend by learning how to create and set up an Angular application from scratch. Next, we'll learn to implement routing, router guards, token-based authentication, authorization, error handling, and dependency injection in an Angular application. Next, we’ll shift our focus to the backend. We'll use Node.js, Express, and MongoDB to create REST APIs. Additionally, we'll learn to create middleware for handling errors, token verification, setting up models and schemas, creating a database using MongoDB, and the concept of separation of concern.


By the end of this module, we’ll understand how to connect both the backend and the frontend to create a full-stack application, as well as how to deploy a fully functional application.

## Setting up the `.env` file
Previously, we discussed what the `.env` (environmental variables) file is all about. To recap, it’s a text file that contains credentials we want to keep secret and secure.

For our use case, three items are kept in the `.env` file:

* `MONGO_URL`: Mongo DB Atlas URL secret

* `JWT_SECRET_KEY`: JSON web token secret key

* `PORT`: Local port
