Express, Passport and JSON Web Token (jwt) Authentication

This post is going to be about creating an authentication with JSON Web Tokens for your project, presumably an API that’s going to be used by Angular, Vue.js or similar frontend frameworks. We’re going to send the jwt with every request, meaning that we don’t rely on sessions, but simply put the token on every request we make to the API. This way you don’t have to worry about cookies, but you can save it in localStorage or other places on the frontend.
