​

Powerful Event System

Hook into critical lifecycle events for fine-grained control:

• Mutator events: insert-before, insert-after, update-before, update-after, delete-before, delete-after.

​

Enhanced Database Communication

The Connection class communicates with the database. It’s based on kysely, so that it generally supports multiple database dialects (but currently only SQLite/LibSQL is supported).

Whether you’re modeling simple data structures or managing complex relationships, bknd’s data tools empower you to build applications with confidence and scalability.
