How to fix error when deploying nest.js on heroku?

Question

Heroku

I'm trying to upload a nest.js application to heroku, here's the error:


main.ts:

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

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  app.setGlobalPrefix('api');
  await app.listen(5000, '0.0.0.0');
}
bootstrap();

I hope for your help

Answer 1

heroku defaults to port 80 or 443 and you are trying to start on 5000.

await app.listen(process.env.PORT || 80, '0.0.0.0');
