In this tutorial, we will learn how to build a full stack Node.js Express + Vue.js Authentication example. The back-end server uses Node.js Express with jsonwebtoken for JWT authentication and Sequelize for interacting with MySQL database & Authorization. The front-end will be created with Vue and Vuex. We’ll also use vee-validate to perform Form validation and vue-fontawesome for make our UI more comfortable to view.

JWT (JSON Web Token)

Comparing with Session-based Authentication that need to store Session on Cookie, the big advantage of Token-based Authentication is that we store the JSON Web Token (JWT) on Client side: Local Storage for Browser, Keychain for IOS and SharedPreferences for Android… So we don’t need to build another backend project that supports Native Apps or an additional Authentication module for Native App users.

There are three important parts of a JWT: Header, Payload, Signature. Together they are combined to a standard structure: header.payload.signature.

The Client typically attaches JWT in x-access-token header:

x-access-token: [header].[payload].[signature]

Node.js Express Vue.js Authentication example

It will be a full stack, with Node.js Express for back-end and Vue.js for front-end. The access is verified by JWT Authentication.

• User can signup new account, login with username & password.
• Authorization by the role of the User (admin, moderator, user)
