This tutorial shows you how to maintain thorough API documentation by using Swagger with an Express API in Node.

We all know about the importance of documenting your APIs. In terms of Node APIs, whether they were built on top of Express or any other framework, you’ve got plenty of open source options out there. These include apiDoc, docbox, and others.

In this tutorial, however, we’re going to explore Swagger usage along with an Express API.

Swagger is an open source set of tools that enable you to design, build, document, and use RESTful web services. It was created to be mostly agnostic, which means that you can use it with pretty much any of your favorite languages and frameworks.

In our example, we’ll be making use of the two libraries: swagger-ui-express and swagger-jsdoc.

The first is a module that allows you to feed a Swagger UI (auto-generated views based on the swagger-ui project) from a swagger.json file, or from an inline object.

The second project is about integrating Swagger using JSDoc comments throughout your code. This is pretty useful, especially when you have extensive APIs and dozens of models.
