What Is a Laravel Migration?
A Laravel migration is a version-controlled blueprint for your database schema, written in PHP using the Laravel Schema Builder. Migrations let you define, modify, and share database tables across your team without writing raw SQL.
This is used for:
- Rapid Prototyping: Turn a sample JSON payload instantly into a database table definition.
- API-First Development: Generate migrations directly from your API response samples.
- Consistent Schema: Ensure all team members start from the same generated migration file.
