The Library Manager provides an admin dashboard for managing books library using secure REST API endpoints, and a React single-page application.

Description

Library Manager creates a dedicated book management system inside the WordPress admin area. It uses a custom database table to store book records and exposes a structured REST API for CRUD operations. The admin interface is powered by a bundled React application and provides features such as pagination, filtering, searching, and inline editing.
