In this chapter, we started by using an AWS EC2 instance to create an API from Node.js to PostgreSQL. We practiced installing Node.js and created an Express Node.js app. Then we learned how to set up a PostgreSQL database connection with Node.js. Going ahead, we set up API routes in Node.js, the Angular module, and the controller. We learned how to set up an Angular view and re-structured the app. Finally, we learned how to create a BDD/TDD library with Mocha and Chai.
In the next chapter, we will demonstrate how to install and configure PostgreSQL to use it with a Django application.
