This is a Book Search Engine that has been converted from RESTful APIs to a GraphQL API which uses the Apollo Server. This application was built using the MERN Stack – MongoDB database. Express.js Server, React front-end and Node.js. It is set up to allow users to save their favorite book searches on the backend.


Readers are able to either login or signup on this Book Search Engine, with an account accessing the full features of the website while those with not logged in or with no account are limited to searches only and cannot save their searched books.
