How to Use Migrations

Prerequisites

• Install TypeORM CLI: npm install -g typeorm
• Add the ormconfig.json file (use configuration from app.module.ts with valid DB connection values)

Create and apply a new migration

1. Do the required changes to the entity classes.
2. Recompile the code (npm run build) and make sure your database has all previous migrations applied.
3. Generate a migration: typeorm migration:generate -n <migration-name> -o
4. Verify the generated SQL code in the new file in the migration folder.
5. Update the database: typeorm migration:run
   If you need to revert: typeorm migration:revert (will revert one migration)

Hint: Set migrationsRun: true in the TypeORM config to automatically apply all pending migrations on application start.
