[SOLVED]
ormconfig is no longer supported after version 0.3.0
Solution
In a nutshell: TypeORM is expecting to find a DataSource() instance.
How to do this?
Short answer
// datasource.ts
import { DataSource } from 'typeorm';
const ormConfig = { /* Add your config here */ };
export default new DataSource(OrmConfig);
Then use the -d in the TypeORM command to specify the path to the datasource.
Example: typeorm migration:generate path/to/Migration -d path/to/datasource
Long answer
// orm.config.ts
import { DataSource } from 'typeorm';
// Note: use your corresponding Database config
import { PostgresConnectionOptions } from 'typeorm/driver/postgres/PostgresConnectionOptions';
// General DB connection config
const ormConfig: PostgresConnectionOptions = {
type: 'postgres',
host: process.env.DB_HOST,
port: parseInt(<string>process.env.DB_PORT),
username: process.env.DB_USERNAME,
password: process.env.DB_PASSWORD,
database: process.env.DB_NAME,
logging: true,
entities: ['path/to/entities'],
migrations: ['path/to/migrations'],
synchronize: false,
ssl: true,
};
export default new DataSource(ormConfig);
package.json
"scripts": {
"migration:create": "typeorm migration:create ./path/to/migration",
"migration:generate": "typeorm migration:generate -d ./path/to/datasource ./path/to/migration",
"migration:run": "typeorm migration:run -d ./path/to/datasource"
},
