Introduction (https://jwt.io)

I have a great introduction to JWT in one of my other repositories, click here to take a look!

How to use this code?

1. Make sure you have the latest stable version of Node.js installed

$ sudo npm cache clean -f
$ sudo npm install -g n
$ sudo n stable

2. Configure your database and jsonwebtoken in config/env. E.g.:

module.exports = {
  mysql: {
    host: 'localhost',
    port: 3306,
    database: 'jwt_dev',
    username: 'root',
    password: 'root',
  },
  jwt: {
    jwtSecret: '$eCrEt',
    jwtDuration: '2 hours',
  },
};

3. Fork this repository and clone it

$ git clone https://github.com/<your-user>/node-jwt

4. Navigate into the folder

$ cd node-jwt

5. Install NPM dependencies

$ npm install

6. Make sure you have a MySQL DB up and running, if you don't, using docker is the easiest way

$ docker run -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -d mysql

Login into the container, update the root user and create databases

$ docker exec -it <CONTAINER ID> mysql -uroot -proot
$ ALTER USER root IDENTIFIED WITH mysql_native_password BY 'root';
$ CREATE DATABASE jwt;
$ CREATE DATABASE jwt_dev;
$ CREATE DATABASE jwt_test;

7. Run the project

$ node index.js

8. Or use nodemon for live-reload

$ npm start

npm start will run nodemon index.js.

9. Navigate to http://localhost:8000/api-status in your browser to check you're seing the following response

{ "status": "ok" }

The port can be changed by the setting the environment variable PORT

10. If you want to execute the tests

$ npm test

npm test will run mocha.

11. If you want to test it manually you can do it with the following commands

Register a new user:

curl -X POST 'http://localhost:8000/users?username=admin2&password=admin'

Sign in with the new user credentials:

curl -X POST 'http://localhost:8000/auth?username=admin&password=admin'

Copy the token and send a request to get all current users:

curl -X GET http://localhost:8000/users -H 'Authorization: Bearer <JWT_TOKEN>

12. And that's it, congrats! You should get a similar response to this one, meaning that you're now authenticated
