add controller

close(signal?: ShutdownSignal)

Close the application.

enableShutdownHooks(signals?: ShutdownSignal[]): this

Enables the usage of shutdown hooks. Will call the onApplicationShutdown function of a provider if the process receives a shutdown signal.

get(path: string, middleware: NestMiddleware)

Only give a simple quick start example here, not recommended to use it for complex functions.

Because it is not subject to the overall framework process framework and is not associated with guards, interceptors, filters, etc.

Its execution order with middleware is also not guaranteed by the framework, for example, oak middleware will be executed first, but the hono may see the order get and middlewares.

init(appModule: ModuleType, caches?: FactoryCaches)
listen(options?: ListenOptions): Promise<void>
setGlobalPrefix(apiPrefix: string)
use(...middlewares: (NestMiddleware | Constructor<INestMiddleware>)[]): Promise<void>

use middlewares

useLogger(logger: LoggerService | false): void

Sets custom logger service.

useOriginMiddleware(originMiddleware: Function, path?: string): void

use the origin middleware, not recommend to use if you don't know what you are doing.

useStaticAssets(path: string, options?: { prefix?: string; })

Sets a base directory for public assets.
