Details

• Routes can be annotated using the @api_version decorator
  • This essentially says, "This route is available from version (major, minor) onward, until a new version of the route is defined."
• Use the versionize function on your FastAPI app to perform the versionizing magic
  • Each version results in a new mounted FastAPI sub-application with a version prefix you define
  • Unlike fastapi_versioning, this does not return a new FastAPI app, but applies the versioning directly to the app you provide
  • You can generate a "latest" alias for the latest version using enable_latest and latest_prefix
  • You can customize your OpenAPI schemas at runtime using get_openapi
    • This will be used to override the openapi function of all versioned FastAPI sub-applications
  • You can generate each versioned Swagger page using get_docs and docs_url
    • This is useful if you need to want to customize your Swagger HTML using fastapi.openapi.docs.get_swagger_ui_html
    • See the Advanced Example for more details
  • You can generate each versioned Redoc page using get_redoc and redoc_url
    • This is useful if you need to want to customize your Redoc HTML using fastapi.openapi.docs.get_redoc_html
    • The usage of this is very similar to get_docs
  • You can sort the routes within a version to occur by route-path-name using sorted_routes see the Sorted Example for more details.
  • You can pass additional kwargs that will be supplied to each versioned sub-application
    • Note: app.title and app.description are automatically supplied to each versioned sub-application
    • For all other FastAPI parameters, these must be passed via kwargs
    • If you want a custom title and description for each versioned docs page, you can use get_docs and/or get_redoc
    • Note: If you want docs pages to be generated, you must pass either docs_url or redoc_url as kwargs
    • Note: If you want to specify custom responses, these must be defined on your FastAPI app (not via kwargs)
      • See the Advanced Example for more details
