Steps to reproduce or a small repository showing the problem:

Hello, I’m trying to run migrations. I have a dotenv configuration file for each non-production environment per the dotenv instructions (.env.development, .env.test, etc.). However, when I run migrations I get the error:

Error: No connection options were found in any of configurations file.

I’ve tried explicity setting the file with --config .env.development and I’ve tried leaving things blank. How should I be specifying this file?

I have the same problem here. I verified the code base and I noticed that the TypeORM doing loading .env file, overriding my dotenv rules.

See how my environment files are configured.

// >>> env.ts
import dotenv from 'dotenv';
import path from 'path';

const envFile = process.env.NODE_ENV ? `.env.${process.env.NODE_ENV}` : '.env';
const envPath = path.resolve(__dirname, `../../${envFile}`);

dotenv.config({
  path: envPath,
});

// >>> ormconfig.ts
import '@config/env';

const { DB_TYPE, DB_USER, DB_PASS, DB_NAME, DB_HOST } = process.env;

module.exports = [
  {
    type: DB_TYPE || 'postgres',
    name: 'default',
    host: DB_HOST,
    username: DB_USER,
    password: DB_PASS,
    database: DB_NAME,
    entities: ['src/modules/**/infra/typeorm/entities/*.ts'],
    migrations: ['src/shared/infra/typeorm/migrations/*.ts'],
    cli: {
      migrationsDir: 'src/shared/infra/typeorm/migrations',
    },
    migrationsTableName: '_migrations',
  },
];

I believe that what is causing problems is the excerpt below. We should and could have a way to avoid this behavior.

I have the same problem. I have a file with typeorm configuration src/config/typeorm.ts

export default {
    type: "postgres",
    host: process.env.DB_HOST,
    port: parseInt(process.env.DB_PORT),
    username: process.env.DB_USERNAME,
    password: process.env.DB_PASSWORD,
    database: process.env.DB_NAME,
    schema: process.env.DB_SCHEMA,
    logging: process.env.DB_LOGGING == 'true',
    sync: process.env.DB_SYNC == 'true',
    entities: ["dist/**/*.entity{.ts,.js}"],
    migrations: ["dist/migrations/*{.ts,.js}"],
    cli: {
        migrationsDir: "migrations"
    }
}

I couldn’t execute typeorm migration:run --config dist/src/config/typeorm.js because dotenv doesn’t apply enviroment variables. And it seems --config development.env or --config .env.development will not work because the file contains just text wich describe enviroment variables. Please advise how to apply config which uses environment variables.
