User Authentication Using JWT token
This project is the User Authentication operation. such as Userlogin, Usersignup, GetUserProfile, DeleteUser, Userlogout, and UserUpdate. Any project requires an Authorized mechanism. For example, if you create an e-commerce website or application, you’ll need this LoginModel to store all customer data.
Functionality :
When someone visits your app for the first time, they must first create an account and then log in to your app. Only go to the home page if the user is logged in; otherwise, do not. This type of functionality is commonly found in real-time applications. This is a login model with a JWT token that is being tested with the Jest package. The main operations in this app are Create, Read(Get), Update, and Delete. All operations are linked to a JWT token, which means that once you log in to your app, you can only perform other operations such as get, update, delete, and so on.
