Swift OpenAPI Hummingbird

Hummingbird transport for OpenAPI generator.

// Create your router.
let router = Router()

// Create an instance of your handler type that conforms the generated protocol
// defining your service API.
let api = MyServiceAPIImpl()

// Call the generated function on your implementation to add its request
// handlers to the app.
try api.registerHandlers(on: router)

// Create the application and run as you would normally.
let app = Application(router: router)
try await app.runService()

RequestContext

It is a common requirement that the router RequestContext is used in OpenAPI endpoints. You can do this by adding a middleware that stores your RequestContext type in a TaskLocal.

struct RequestContextMiddleware: RouterMiddleware {
    typealias Context = MyRequestContext
    @TaskLocal static var requestContext: Context?

    func handle(_ request: Request, context: Context, next: (Request, Context) async throws -> Response) async throws -> Response {
        try await Self.$requestContext.withValue(context) {
            try await next(request, context)
        }
    }
}

If you add a version of this middleware, replacing MyRequestContext with your own RequestContext type, to the end of your router middleware chain then it will be available from your OpenAPI endpoints via RequestContextMiddleware.requestContext.
