In this project let's build Nxt Mart by applying the concepts we have learned till now. This project allows you to practice the concepts and techniques learned till React Course and apply them in a concrete project.

You will demonstrate your skills by creating an app that will fetch data from an internal server using a component, displaying that data, routing concepts, authentication and authorization, and adding responsiveness to the website.

This is an individual assessment. All work must be your own. You can request for the feedback after your project submission in the discussions.
