beam-migrate

This package provides type classes to allow backends to implement SQL DDL support for beam. This allows you to use beam syntax to write type-safe schema generation code. The package also provides features to introspect beam schemas, and support for automatic generation of migrations in SQL and Haskell formats. This is mostly a low-level support library. Most often, this library is used to write tooling to support DDL manipulation in your project, or to enable migrations support in beam backends. For a more turnkey solution for database migrations, consider the beam-migrate command line tool. This provides out-of-the-box support for migrations, schema change management, and version control, based on the features provided in this library.
