Introduction to GraphQL

GraphQL represents a paradigm shift in API development, offering more flexibility and efficiency than traditional REST APIs.

GraphQL is a query language and runtime for APIs that allows clients to request exactly the data they need.

Precise Data Fetching: Request only the fields you need

Single Endpoint: One URL for all operations

3query GetUser($id: ID!) {
4  user(id: $id) {
5    name
6    email
7    posts {
8      title
9      publishedAt
10    }
11  }
12}

GraphQL's flexibility makes it ideal for modern applications with diverse client needs.
