Graphql Development Tutorials, Guides & Insights

• Efficiency: Reduce the number of network requests and the amount of data transferred.
• Flexibility: Clients can query only the data they need.
• Evolvability: APIs can evolve without breaking existing queries by adding new fields and types.

In this section, we will set up a simple GraphQL server using Node.js, Express, and Apollo Server. We will create an API for managing a list of books.

• Add a Book

     mutation {
       addBook(title: "1984", author: "George Orwell") {
         title
         author
       }
     }
