Bootstrapping

Every Nest.js application needs to be bootstrapped. This is done by by using the NestFactory to create the root module and calling the listen() method.

In our example application, the entry point is main.ts and we use the async / await pattern to create the AppModule and call listen():

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  await app.listen(3000);
}
bootstrap();
