Building a Library Management System with Harper
Blog post from Harper
A Library Management System is developed using Harper, demonstrating its efficiency in creating robust APIs through a simplified process of building and managing a catalog of books and library members. The system's core components include Book Management and Member Management, each utilizing CRUD operations for handling data. Books and members are defined through a GraphQL schema, automatically creating database tables and exposing them via REST and GraphQL endpoints. The functionality is implemented using resource classes that manage HTTP requests for creating, retrieving, updating, and deleting both books and members. The implementation showcases Harper's ability to seamlessly integrate database and API layers, providing a scalable, extensible, and maintainable solution that can be expanded with additional features like reservations or late fees. The system is tested by running the Harper instance, which sets up the necessary infrastructure, allowing HTTP calls to the service. This project exemplifies the power of Harper in building efficient and straightforward APIs, suitable for various library management needs.
