# NestJS

Progressive TypeScript framework built on top of Express (or Fastify). Opinionated, uses decorators and dependency injection. Hostinger runs Nest apps in server mode.

**`app_type`:** `nest`

## Server mode

NestJS is server-only.

### `package.json`

```json
{
  "scripts": {
    "build": "nest build",
    "start": "nest start",
    "start:prod": "node dist/main"
  },
  "dependencies": {
    "@nestjs/core": "^10.0.0",
    "@nestjs/common": "^10.0.0",
    "@nestjs/platform-express": "^10.0.0"
  }
}
```

### `src/main.ts`

Make sure your bootstrap listens on `process.env.PORT`:

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

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  await app.listen(process.env.PORT ?? 3000);
}
bootstrap();
```

### hPanel settings

| Field            | Value          |
| ---------------- | -------------- |
| Application type | `nest`         |
| Build script     | `build`        |
| Output directory | `dist`         |
| Entry file       | `dist/main.js` |

## Static mode

Not applicable. Nest can serve static files via `ServeStaticModule`:

```ts
import { ServeStaticModule } from '@nestjs/serve-static';
import { join } from 'path';

@Module({
  imports: [
    ServeStaticModule.forRoot({
      rootPath: join(__dirname, '..', 'public'),
    }),
  ],
})
export class AppModule {}
```

## Notes

* **Bind to `process.env.PORT`.** Don't hardcode a port number.
* For Fastify as the underlying HTTP adapter, use [Fastify](/node.js/overview-1/fastify.md)'s notes too — switch via `NestFactory.create<NestFastifyApplication>(AppModule, new FastifyAdapter())`.
* TypeScript config (`tsconfig.json`) should emit to `dist/` to match the entry file path.
