GraphQL is a query language to retrieve data from a server. It is an alternative to REST, SOAP, or gRPC in some way.

GraphQL is a new API standard and offers a revolutionary approach to building data-driven applications. The project was first created by Facebook while they were shifting their mobile app from HTML5 to a native mobile app.

GraphQL follows the same set of constraints as REST APIs, but it organizes data into a graph using one interface. Objects are represented by nodes (defined using the GraphQL schema), and the relationship between nodes is represented by edges in the graph. Each object is then backed by a resolver that accesses the server’s data.

In this article, we will cover the following topics:

  1. What are GraphQL and its use cases?
  2. Key differences between REST and GraphQL. Which types of problems are solving by GraphQL that is created by REST API?
  3. Why GraphQL is getting more popular day by day?
  4. GraphQL implementation using spring boot, JPA, and MySQL database for a blog server
