Integrate Swagger into the App
Discover how to integrate Swagger into the NestJS app.
Swagger is a popular open-source framework that simplifies API design, documentation, and testing. By integrating Swagger into our NestJS application, we unlock a range of benefits that go beyond mere testing.
Swagger serves as a powerful tool for enhancing collaboration among developers. Its interactive playground makes it easy for developers to explore and test API endpoints. This not only simplifies the debugging process but also fosters better understanding and communication within the development team.
One of the standout features of Swagger is its automatic API documentation generation. This means the API specification is always in sync with the code, reducing the risk of outdated or inaccurate documentation. This dynamic synchronization ensures that the development and documentation processes remain aligned, saving time and preventing potential misunderstandings.
Note: API documentation is a comprehensive reference for developers. It outlines how to interact with a particular software application or service programmatically, including details on endpoints, request formats, authentication methods, error handling, and more.
Set up Swagger
NestJS, in conjunction with its dedicated Swagger module (@nestjs/swagger), offers a straightforward setup and configuration process. This integration makes Swagger a natural and efficient choice for NestJS application development.
To integrate Swagger into our NestJS application, we start by installing the necessary dependencies using npm:
npm install --save @nestjs/swagger swagger-ui-express
This command installs the required Swagger modules for our project. But now we let’s configure Swagger ...
