createController

Summary

Defines a controller whose action keys and params are checked against a route map.

This helper returns the controller unchanged while giving TypeScript the route map it needs to type each action's context.params. If controller middleware adds context values, those values are available to the controller actions.

Signature

function createController<
  routes extends RouteMap<string>,
  context extends RequestContext<any, any>,
  middleware extends readonly AnyMiddleware[],
>(
  routes: routes,
  controller: Controller<routes, context, middleware>,
): Controller<routes, context, middleware>

Parameters

routes

controller

The controller object to type-check.

Returns

The same controller value.
