Current behavior

If you test to start Mongo TypeORM example, with start:prod command the console output this error :

[ExceptionHandler] Unexpected token import
/Users/robin/nestTest/examples/13-mongo-typeorm/src/photo/photo.entity.ts:1
(function (exports, require, module, __filename, __dirname) { import { Entity, Column, ObjectIdColumn, ObjectID } from 'typeorm';
                                                              ^^^^^^

I’ve try to find a solution on the internet but without success 😕

Minimal reproduction of the problem with instructions

Pull https://github.com/nestjs/nest/tree/master/examples/13-mongo-typeorm And run this commands : npm install npm run start:prod

Environment

@fwoelffel @kamilmysliwiec exactly, but you can’t use the same ormconfig.json for developement and prodcution. So I created a config file for my environments and load it using the process.env.NODE_ENVvar.

src/config.env.ts :

const config = {
 development: {
        cors: true,
        port: 8001,
        prefixApi: 'api',
        ormtype: {
            type: 'mongodb',
            host: 'localhost',
            port: 27017,
            database: 'my-database',
            username: 'user',
            password: 'password',
            authSource: 'admin',
            synchronize: true,                       
            entities: ['src/**/**.entity{.ts,.js}'],
        },
    },
    production: {
        cors: false,
        port: 8001,
        ormtype: {
            type: 'mongodb',
            host: 'localhost',
            port: '27017',
            username: 'user',
            password: 'password',
            database: 'my-database',
            authSource: 'admin',
            synchronize: false,                       // <-- recommended by typeorm docs 
            entities: ['dist/**/**.entity{.ts,.js}'], // <-- changed src directory to dist
        },
    },
};

const envConfig = config[process.env.NODE_ENV || 'development'];

export default envConfig;

src/app.module.ts :

...
import envConfig from './config.env';

const {ormtype: ormConfig} = envConfig;

@Module({
    imports: [
        TypeOrmModule.forRoot(ormConfig),
       ...
    ],
})
export class ApplicationModule implements NestModule {}

Note that TypeORM is looking for entities using the following path:

13-mongo-typeorm/src/photo/photo.entity.ts

Production build is inside dist directory, not src. In order to fix that you have to modify ormconfig.json.
