Usage

To create a global-scoped filter, you would do the following:

// main.ts
async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  app.useGlobalFilters(new GlobalExceptionFilter());
  await app.listen(3000);
}
bootstrap();

To instantiate a microservice

// main.ts
async function bootstrap() {
  const app = await NestFactory.create(AppModule);
    AppModule,
    {
      transport: Transport.TCP,
    },
  );
  app.useGlobalFilters(new GlobalRpcExceptionFilter());
}
bootstrap();

The following example uses a manually instantiated method-scoped filter. Just as with HTTP based applications, you can also use controller-scoped filters (i.e., prefix the controller class with a @UseFilters() decorator).

@UseFilters(new GlobalRpcExceptionFilter())
@MessagePattern({ cmd: 'sum' })
accumulate(data: number[]): number {
  return (data || []).reduce((a, b) => a + b);
}
