Did you know you can use Node.js and Express to build a web API that can push and pull data from your applications via HTTP? You don't have to learn ASP.NET or Python. You don't even have to know that much about back-end programming. In this course, Emmanuel Henri shows you how to create a simple, RESTful web API with these two popular javascript libraries. He guides you through how to set up the project, including the Express server and testing environment, and create the endpoints that you need to add, update, and delete data from a MongoDB database. Plus, Emmanuel demonstrates how to serve static files such as images with your new API and explores additional libraries that can help streamline API development, such as Koa and LoopBack.
