Express Server JWT

A simple server with JWT authentication with the ability to create new users, and to authenticate the existing ones.

Requirements

• Node.js
• NPM
• Docker or MongoDB locally

Endpoints:

• /api/register - POST (email, password)
• /api/login - POST (email, password)
• /api/validate - GET (checks for authorization in HEADER which contains token)

Get Started:

Install all dependencies:

npm install

Configure the server:

touch config.js

# configuration should look like this:
module.exports = {
  db: 'mongodb://localhost/your-db-name-here',
  port: 3001,
  secret: 'secret word for JWT'
};

In case you dont have MongoDB installed locally, you can use docker image.

Pull image and run it for the first time:

docker run -it -p 27017-27019:27017-27019 --name mongodb mongo:4.0.4

Stop container:

docker stop mongodb

Start container:

docker start mongodb

Configure MongoDB server:

• Create new database
• Create collection called "users"

Run App backend:

npm start

Useful things

If you are not familiar with MongoDB, I suggest to install "MongoDB Compass" to easily manage Mongo Database via GUI.
