More information about the architecture of the API can be found in this Medium story : https://medium.com/@phcollignon/node-rest-api-jwt-in-typescript-e6a8ae5cd8f8

• This is a simple Node Rest Api written in Typescript.
• Routes can be protected with JWT tokens.
• Authentification with Passport.

• The API dispatches requests with well structured routes.
• Routes are using controllers for API implementations.
• Controllers are using models for Mongo persistence.
• Routes can be protected with JWT authentification middelwares :

import { Router } from "express";
import { ProductController } from "../controllers/productController";
import { AuthController } from "../controllers/authController";


export class ProductRoutes {

    public router: Router;
    public productController: ProductController = new ProductController();
    public authController: AuthController = new AuthController();

    constructor() {
        this.router = Router();
        this.routes();
    }

    routes() {
        this.router.get("/", this.productController.getProducts);
        this.router.get("/:id", this.productController.getProduct);
        // The following routes are protected
        this.router.post("/", this.authController.authenticateJWT, this.productController.createProduct);
        this.router.put("/:id", this.authController.authenticateJWT, this.productController.updateProduct);
        this.router.delete("/:id", this.authController.authenticateJWT, this.productController.deleteProduct);
    }
}

• Clone the repository

git clone https://github.com/Philippe-Collignon/rest-api-node-jwt-typescript.git

• Install dependencies

cd rest-api-node-jwt-typescript
npm install
npm run build

• Launch demo Node and Mongo server in docker containers

docker-compose build
docker-compose up

( Alternatively, you can run and configure your local or cloud Mongo server and start Node server with npm run build && npm start)

Please check package.json for other useful npm scripts (for example typescript and nodemon watchers in development)

Send a POST request to http:https://localhost:3000/api/user/register with the following payload ** :

{
	"username": "me",
	"password": "pass"
}

You should get a JWT token in the response :

{
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6Im1lMiIsImlhdCI6MTU1MDU4MTA4NH0.WN5D-BFLypnuklvO3VFQ5ucDjBT68R2Yc-gj8AlkRAs"
}

**Note - Please protect your registration API if you do not use any third-party identity provider !!.

Send a POST request to http:https://localhost:3000/api/products with the following payload :

{
  "productId": "13",
  "name": "Orange",
  "price": 5,
  "quantity": 6
}

You should get an authorization denied !

{
  "status": "error",
  "code": "unauthorized"
}

Add the JWT token to the Authorization header :

Content-Type: application/json
Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6Im1lMiIsImlhdCI6MTU1MDU4MTA4NH0.WN5D-BFLypnuklvO3VFQ5ucDjBT68R2Yc-gj8AlkRAs

You should have created the product !!

{
  "data": {
    "_id": "5c6c0845e3eb8302ffd168c0",
    "productId": "13",
    "name": "Orange",
    "price": 5,
    "quantity": 6,
    "__v": 0
  }
}

You can get the product with or without token because the Get route of Product router is not protected with the JWT authentification middelware. Send a GET request to http:https://localhost:3000/api/products/13

You should get :

[
  {
    "_id": "5c6bfc97e3eb8302ffd168be",
    "productId": "13",
    "name": "Orange",
    "price": 5,
    "quantity": 6,
    "__v": 0
  }
