Description

OpenSya Persistence gives TypeScript applications a consistent runtime for executing domain rules around data.

It handles type inference, validation, relations, lifecycle hooks, transactions, audit logs and domain events while remaining framework-agnostic and independent from the underlying database.

OpenSya Persistence powers OpenSya, but can be used in any JavaScript or TypeScript application.

Philosophy

• Define once

Metadata is the source of truth for types, validation, relations and runtime behavior.

• Execute consistently

Every operation follows the same domain rules, regardless of where it is executed.

• Stay in control

Persistence works above the database adapter. Use Drizzle today, or provide your own adapter tomorrow.
