In this tutorial, we’re gonna build a Node.js Express Rest API example that supports Token Based Authentication with JWT (JSONWebToken). You’ll know:

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 Authorization header with Bearer prefix:
Authorization: Bearer [header].[payload].[signature]
Or only in x-access-token header:
x-access-token: [header].[payload].[signature]

This is our Node.js application demo running with MySQL database and test Rest Apis with Postman.
These are APIs that we need to provide:
Methods | Urls | Actions |
---|---|---|
POST | /api/auth/signup | signup new account |
POST | /api/auth/signin | login an account |
GET | /api/test/all | retrieve public content |
GET | /api/test/user | access User's content |
GET | /api/test/mod | access Moderator's content |
GET | /api/test/admin | access Admin's content |
A legal JWT must be added to HTTP x-access-token Header if Client accesses protected resources.
Via Express routes, HTTP request that matches a route will be checked by CORS Middleware before coming to Security layer.
Security layer includes:
If these middlewares throw any error, a message will be sent as HTTP response.
Controllers interact with MySQL Database via Sequelize and send HTTP response (token, user information, data based on roles…) to client.
