Nest: Mongo TypeORM example don't work in production

[chanlito]

@RobinPrette did u try with "moduleResolution": "node", in tsconfig.json?

[RobinPrette]

@chanlito I've just try with it but that doesn't work

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.

If you are using the path to your entity files when initializing the TypeORM connection, make sure you give the path to the dist folder, as shown here https://docs.nestjs.com/techniques/sql

@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 {}
