Swagger 2.0 data model.

The original Swagger 2.0 specification is available at http://swagger.io/specification/.

Usage

This library is intended to be used for decoding and encoding Swagger 2.0 API specifications as well as manipulating them.

Please refer to haddock documentation.

Some examples can be found in examples/ directory.

Trying out

All generated swagger specifications can be interactively viewed on Swagger Editor.

Ready-to-use specification can be served as JSON and interactive API documentation can be displayed using Swagger UI.

Many Swagger tools, including server and client code generation for many languages, can be found on Swagger’s Tools and Integrations page.

Contributing

We are happy to receive bug reports, fixes, documentation enhancements, and other improvements.

Please report bugs via the github issue tracker.
