Created page with " =Setup= <syntaxhighlight lang="JavaScript"> $ npm i -g @nestjs/cli $ nest new project src ........app.controller.ts # The entry file of the application. It uses NestFact..."

New page

=Setup=
<syntaxhighlight lang="JavaScript">

$ npm i -g @nestjs/cli
$ nest new project

src
........app.controller.ts # The entry file of the application. It uses NestFactory to create the Nest application instance.
........app.module.ts # Defines AppModule, the root module of the application.
........main.ts # Basic controller sample with a single route.

</syntaxhighlight>

The main.ts includes an async function, which will bootstrap our application:

main.ts:
<syntaxhighlight lang="JavaScript">
import { NestFactory } from '@nestjs/core';
import { ApplicationModule } from './app.module';

async function bootstrap() {
const app = await NestFactory.create(ApplicationModule);
await app.listen(3000);
}
bootstrap();
</syntaxhighlight>

To create a Nest application instance, we are using the NestFactory. NestFactory is one of the most fundamental classes, it exposes a few static methods that allows creating application instance. The create() method returns an object, which fulfills the INestApplication interface, and provides a set of usable methods which are well described in the next chapters.

=Running application=
Once the installation process is complete, you can run the following command to start the HTTP server

<source>
$ npm run start
</source>

This command starts the HTTP server on the port defined inside the src/main.ts file. While the application is running, open your browser and navigate to '''http://localhost:3000/'''. You should see the Hello world! message.
