How to give a jwt token to a client?

Question

JSON Web Token

We were given the task to make an application on a react-client and a node-back. I don’t really understand how to transfer the token to the user on the client side. I check the rest api requests through postman (such an http client), and in the headers I write:

Authorization: Bearer ejsSIaisi...-тут идет сам токен

. Okay, that's understandable. And how are these tokens written to the client in general? As I understand it, they are saved, for example, in local storage. And how to save?
How do you implement jwt authorization?

Answer 1

The user enters a login, password, sends to the server in response you give him a signed token, with some encrypted information. You can save it anywhere, in cookies, in local storage, it doesn't matter.
Now the user sends a request and passes the token (as a header, in the request, or whatever), we verify the token, get the information = we know what kind of user and other information.
