So, in summary, Swagger’s main advantage is that it makes the API development process faster and more efficient.

We can customize the API documentation however we like.

Everyone involved in product development, including product managers, stakeholders, and developers, can try out API in UI without needing to run the server independently. That way, developers who work in frontend can understand how the API works and integrate the APIs into the client side.Īnother benefit of using Swagger is that it’s comprehensive for developers and non-developers. Swagger synchronizes the API between the client and server side of the application. One significant benefit of Swagger is that it helps to understand how API works for the client side of an application. This is useful, especially when you have extensive APIs and dozens of models.īefore we get into the Swagger integration into your Node.js application, let’s examine why Swagger is important for any application - how it helps in the development process. The second project is about integrating Swagger using JSDoc comments throughout your code. 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 an inline object. In our example, we’ll use two libraries: swagger-ui-express and swagger-jsdoc. It was created to be mostly agnostic, meaning you can use it with pretty much any of your favorite languages and frameworks. Swagger is an open source set of tools that enable you to design, build, document, and use RESTful web services. In this tutorial, we will explore using Swagger with an Express.js API. These include apiDoc, docbox, and others. In terms of Node.js APIs, whether they were built on top of Express.js or any other framework, you’ve got plenty of open source options. We all know about the importance of documenting your APIs. This update also addresses errors in the code present in the previous version. Creator of Documenting your Express API with SwaggerĮditor’s note: This post on documenting an Express.js API with Swagger was last updated on 9 December 2022 to add sections on how to connect Swagger to Node.js, the benefits of Swagger, and how to use CSS to customize Swagger.
