Details

Outdated API documentation is the most common source of friction between teams. This template reads route definitions, types and comments from the code repository, generates an OpenAPI specification and readable documentation, and automatically updates the affected sections in any merge request that changes an interface.

The documentation includes request examples, response examples and error code descriptions. Example data is generated from type definitions, so nothing needs to be maintained by hand. Change history is recorded by version to help callers assess upgrade impact.

  • Supports mainstream TypeScript, Java, Python and Go frameworks
  • Generates OpenAPI 3 specifications and HTML documentation
  • Automatic sync on interface changes
  • Version-to-version diff
