Standalone applications ​

If you initialized your application with the Nest CLI, Express framework will be installed by default along with Nest. Nest and NestJS Telegraf does not require Express for work. So if you don't plan to getting bot updates through webhooks, and you don't need a web server, you can remove Express.

To do this, change the bootstrap function in the main.ts file of your project on something like that:

async function bootstrap() {
  const app = await NestFactory.createApplicationContext(AppModule);
}
bootstrap();

This initializes Nest as a standalone application (without any network listeners).

All that remains is to remove unused dependencies:

npm un @nestjs/platform-express @types/express
