ASP.NET Core in Action, 3e
Swashbuckle is a .NET library that generates OpenAPI documents and provides middleware for serving and visualizing them in ASP.NET Core applications.
- How it is used
- Generates and serves OpenAPI descriptions for ASP.NET Core APIs and enables browser-based exploration through Swagger UI.
- How deep it goes
- Walks through package installation, service and middleware setup, metadata refinement, XML comments, and security configuration without detailing generator internals.
- Examples
- Uses a GET-and-POST fruit API, a development-only setup, and a bearer-token configuration for authenticated Swagger UI requests.
- What you can do after
- Operate/configure Swashbuckle to publish an OpenAPI document, test endpoints in Swagger UI, and describe protected requests.
Building Web APIs with ASP.NET Core
Swashbuckle is a .NET toolset that generates OpenAPI descriptions and provides interactive Swagger documentation for ASP.NET Core APIs.
- How it is used
- Generates OpenAPI documentation and an interactive browser client so developers can discover and test ASP.NET Core API endpoints.
- How deep it goes
- Walks through service and middleware setup, verification, and endpoint tagging; identifies deeper generator customization without detailing its filter implementation.
- Examples
- Uses Program.cs registration, swagger.json and SwaggerUI URLs, and a SwaggerOperation tag on an authorization endpoint.
- What you can do after
- Operate/configure it to inspect generated API documentation and group Minimal API endpoints with explicit tags.
