• A backend API for managing book data through CRUD operations using Mongoose for interacting with MongoDB
• Endpoints for adding, retrieving, updating, and deleting book records
• Retrieval of all books or specific books by ID (GET request to /book & /book/:id)
• Error handling and middleware setup for CORS policy enforcement

What is CRUD?

• Create, Read, Update, and Delete. Represents the four basic functions that can be performed on most types of data:
  • Create: Allows the creation of new data entries or records in a database.
  • Read: Involves retrieving or accessing existing data entries from a database.
  • Update: Enables modification or alteration of existing data entries in a database.
  • Delete: Involves removing or deleting existing data entries from a database.
