In this course, you’ll learn how to build a full-stack application using the MEAN stack. You’ll begin with the frontend by learning how to create and set up an Angular application from scratch. Furthermore, you’ll learn to implement routing, router guards, token-based authentication, authorization, error handling, and dependency Injection in an Angular application.

Next, the focus shifts to the backend. You’ll learn by using Node.js, Express, and MongoDB to create REST APIs. Additionally, you’ll learn to create middleware for handling errors, token verification, setting up models and schemas, creating a database using MongoDB, as well as the concept of separation of concern.

By the end of this course, you will have an understanding of how to connect both the backend and the frontend together 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



Learn to set up the .env and the Git ignore files.
