typeorm: MissingDriverError: Wrong driver: "undefined" given.

solved it by export the config this way in my ormconfig.ts:

export = ORMConfig

module.exports = ORMConfig; working for me in latest version.

export = ORMConfig is the old TypeScript module format afaik.

This could be fixed in TypeORM by checking for a default property on the exported object.

Still an issue

@pleerock this is still an issue

Agreed. This issue needs to be reopened.

The following seems to work just fine for me, maybe an update fixed this issue ?

// ormconfig.ts
import { ConnectionOptions } from 'typeorm';
export default {
  type: 'postgres',
  host: 'localhost',
  port: 5432,
  username: 'postgres',
  password: 'pass',
  database: 'filmash',
  entities: ['dist/**/*.entity{.ts,.js}'],
  synchronize: true,
} as ConnectionOptions;

// app.module.ts
import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { ExampleModule } from './example/example.module';
import { TypeOrmModule } from '@nestjs/typeorm';
import connectionOptions from './ormconfig';

const IMPORTED_MODULES = [ExampleModule];

@Module({
  imports: [TypeOrmModule.forRoot(connectionOptions), ...IMPORTED_MODULES],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

is there an update on this particular issue?

I can confirm, @KillerCodeMonkey’s solution works for me 👍

Same error happen（；＾ω＾） But, modify config file

// ormconfig.ts
import { ConnectionOptions } from 'typeorm';

export const config: ConnectionOptions = {
 // hogehoge
};

module.exports = config;

And then, below command, no problem.

// fish. there is no '$' .
npx ts-node (npm bin)/typeorm migration:show

Same here, I just switched my ormconfig.ts file from:

export default connectionOptions;

to:

module.exports = connectionOptions;

Now it works as expected

@KillerCodeMonkey 's solution worked for me. earlier I was doing this :

import { ConnectionOptions } from “typeorm”; … … export const config_test: ConnectionOptions = { name: “default”, type: “postgres”, host:somehost, port:someport, …

I added following line at the end of the file and it started working export default config_test;

I had to set the environment variable: TYPEORM_CONNECTION to postgres

For me there was needed also to configure “typeorm” script as described in typeorm instruction

Somewhere in my code i had an extra:

TypeOrmModule.forRoot(),

Next to the main:

TypeOrmModule.forRoot({
    ...config
})

Deleting the empty one, fixed this issue

@KillerCodeMonkey works excellently, but I was using ormconfig.ts which was imported in another ts file to provide connection details (in TS.ed framework). Had to use import * as config from "./ormconfig.ts" for it to get imported without error.

Seems like, export = config exports as a module. I still don’t understand all different kind of exports yet but this worked for me.

Thanks @bertyhell, I also had an empty TypeOrmModule.forRoot(). Removing the empty one fixed it for me.

Have any of you tried deploying your apps to Heroku? using export I get unexpected token export
