Kompendium is intended to be a non-invasive OpenAPI spec generator for Ktor APIs. By operating entirely through Ktor's plugin architecture, Kompendium allows you to incrementally document your API without requiring you to rip out and replace the amazing code you have already written.

These docs are focused solely on Kompendium 3, previous versions should be considered deprecated and no longer maintained
All Kompendium artifacts are published to Maven Central. Most Kompendium users will only need to import the core dependency
Once we have added the dependencies, installed the NotarizedApplication
plugin. This is an application-level Ktor plugin that is used to instantiate and configure Kompendium. Your OpenAPI spec metadata will go here, along with custom type overrides (typically useful for custom scalars such as dates and times), along with other configurations.
At this point, you will have a valid OpenAPI specification generated at runtime, which can be accessed by default at the /openapi.json
path of your api.
For more detail on the NotarizedApplication
plugin, please see the docs
Once you have notarized your application, you can begin to notarize individual routes using the NotarizedRoute
plugin. This is a route-level Ktor plugin that is used to configure the documentation for a specific endpoint of your API. The route documentation will be piped back to the application-level plugin, and will be automatically injected into the OpenApi specification.
Setting up documentation on a route is easiest achieved by creating an extension function on the Ktor Route
class
Once you have created your documentation function, it can be attached to the route simply by calling it at the desired path.

plugin, please see the docs
