Is JWT necessary over HTTPS communication?

Issue

I'm developing a MEAN stack application, and I'm currently setting up an account system. I've seen several tutorials about Authentication, all using JWT.

I am wondering if, JWT could be used as way to secure communication transport over non-secured connection like HTTP?

I've set up HTTPS to communicate from my Angular 4 front-end to my NodeJS + Express back-end, and thus, wondering if JWT are necessary to secure my communications?

Solution

Nowadays developers prefer Token-Based Authentication instead of Session. Token-Based Authentication has lots of advantages over Session. We use JWT i.e. JSON Web Token to generate a token after user authentication, every time your front-end app makes an API call so your system should check whether the request has a valid token or not if it is there and it is valid then it is considered as the valid user.

In short, we use JWT to validate our API calls it is nothing to do with HTTP or HTTPS
