 * import { NaviosFactory } from '@navios/core'
 *
 * const app = await NaviosFactory.create<BunEnvironment>(AppModule, {

 * // All methods are now type-safe for Bun
 * app.configure({ development: true })
 * app.enableCors({ origin: true }) // BunCorsOptions
 * const server = app.getServer() // Server<undefined>
 * await app.listen({ port: 3000 }) // BunListenOptions
