Video Rental Store RESTful Backend (NodeJS, MongoDB, Jest, TDD)

24 Sep 2020

Code on GitHub

In this project, I used Express to implement a RESTful API for a video rental store backend. I employed TDD using Jest (a wrapper around Jasmine). I also manually tested the endpoints using Postman while developing and for testing the JWT.

Features:

• Input validation
• Middleware - for handling errors (a clean way to set up a try/catch block around the functionality of all of the API calls)
• Configuration section - for storing the private key for the JWT (JSON Web Token), which just ended up referencing an environment variable
• Debugging - Used winston for logging at different levels.
• Database Integration - I used Mongoose to interface with mongoDB to perform the necessary CRUD operations.
• Authentication - bcrypt for hashing passwords. Issues a JWT that some of the API endpoints require to return data.

Here is an example of Jest tests running and giving you a sense of the API.
