Build a REST API With Express

Course Summary

REST services are a powerful way of providing functionality over the internet. Not only can they be used as a foundation to build sophisticated web applications, they can also be integrated into any number of other projects, making them the ultimate in modularity and reusability! Instead of having to rebuild an application for several platforms, for example -- iOS, Android, browser, etc -- you can build the back-end once and just add user interfaces as needed. You can build a REST service in many different languages/platforms, but for this course, we will be building one with Express, a popular framework written for Node.js. We will also use Mongoose with MongoDB to persist our data. Let’s get started!

    Building a REST Service

    Creating a plan is an excellent place to start when building a REST Service. The more well thought out your interface is, the easier it will be for other developers to understand, and the better the chance it will have for widespread adoption (making you a coding superstar). Let’s start by getting an overview of the Service we want to build, and then do a little planning to bring it all to life. 7 steps

    Building API Routes in Express

    We’ve gotten a great start to our service by planning out the resources we want to expose. Now it’s time to actually build our routes into Express. We’ll initiate the project from the command line, then we’ll fire up a code editor to build it up from there. 9 steps

    Modeling Data for the API

    Now that we have an application all set up to handle requests to our API, we need to give it a way to persist data. That starts with getting a clear picture of data it will be handling. We did a lot of the groundwork when we planned the routes, but we’ll need to be very specific when we talk to our database about what we want it to store. 7 steps

    Communicating with Mongo through Mongoose

    While interacting directly with the Mongo database is certainly possible, it can wind up being a hassle. Luckily we have Mongoose to help us manage our interactions with the DB. It takes care of a lot of the details so we can focus more on working with our data, and not our database. Let’s take a look at how we can use this powerful library to tell Mongo how to handle our data, then put the pieces together to complete our Q & A service. 5 steps

    Completing and Testing the API

    It’s finally time to see our service in action! There are all kinds of tools and methods for doing this. We’re going to go with a quick, on-the-fly method that allows us to see right away what is happening with our service. 5 steps
