@next-safe-action

safe-action-validation-errors covers schema and manual validation in next-safe-action, showing how to structure error responses (formatted and flattened), use returnValidationErrors for business logic checks, and display errors on the client.

safe-action-hooks provides react hooks (useAction, useOptimisticAction, useStateAction) for consuming next-safe-action server actions with built-in state and status tracking from client components.
