Current behavior

When I add swagger and swagger-ui for documentation and statics. It doesn't load work. I get errors on the startup.

Following error was provided:

{ Error: ENOENT: no such file or directory, open '//indexTemplate.html'

  errno: -2,

  path: '//indexTemplate.html' }

Expected behavior

Access for swagger should be provided

Minimal reproduction of the problem with instructions

Add swagger to your main.ts file

import { NestFactory } from '@nestjs/core';
import { AppModule } from './src/app.module';
import * as swStats from 'swagger-stats';
import { SwaggerModule, DocumentBuilder } from '@nestjs/swagger';

import { enableProdMode } from '@angular/core';
enableProdMode();

async function bootstrap() {
  const app = await NestFactory.create(AppModule); 
  app.enableCors({
    methods: 'GET',
    maxAge: 3600,
  });

  const options = new DocumentBuilder()
    .setTitle('My-Collection backend')
    .setDescription('The collection api')
    .setVersion('1.0')
    .addTag('reibo')
    .build();

  const document = SwaggerModule.createDocument(app, options);
  SwaggerModule.setup('swagger', app, document);
  app.use(swStats.getMiddleware());

  await app.listen(4000);
}
bootstrap().catch(err => console.error(err));

What is the motivation / use case for changing the behavior?

+1, same error.

Using Universal & Swagger module.

Node v10.5.0
Windows 10

"@nestjs/common": "^5.5.0",
"@nestjs/core": "^5.5.0",
"@nestjs/ng-universal": "^0.1.1",
"@nestjs/swagger": "^2.5.1",

This is caused due to the way in how the underlying swagger UI library works. Unfortunately, we cannot do anything in this case. I'd suggest adding an issue to the swagger-ui-express repository though (lack of webpack compatibility).
