Creating a migration with TypeORM

A migration in TypeORM means a SQL query made to sync an existing schema with the one in source.

To auto-generate migrations for your entities, use the TypeORM CLI.

Like:

typeorm migration:generate -- -d ./dataSource.js ./path/to/NameOfMigration.ts

Where ./dataSource.js is a path to your data source.

And where ./path/to/NameOfMigration.ts is the desired path to the migration.

This command will generate a new file under ./path/to/1584188553162-NameOfMigration.ts, the timestamp given there is an example.

See the TypeORM documentation regarding migrations.
