Demystifying GraphQL for REST Veterans

Transitioning from REST to GraphQL requires a paradigm shift. Instead of requesting data from specific endpoints, you query a graph of interconnected data.

The Over-fetching Problem

REST often forces clients to accept more data than they need. GraphQL solves this fundamentally by allowing clients to specify exactly the shape and depth of the response they require.

query GetUser {
  user(id: "123") {
    name
    email
    posts {
      title
    }
  }
}

This precision reduces payload sizes and improves performance on constrained networks.
