GraphQL-GraphQL schema and API builder

Comprehensive Introduction to GraphGraphQL Functions and UsersQL

GraphQL is a query language for APIs and a runtime for executing those queries by using a type system you define for your data. Originally developed by Facebook in 2012 and open-sourced in 2015, GraphQL provides a more efficient, powerful, and flexible alternative to REST. Unlike REST, where you have to deal with multiple endpoints to retrieve related data, GraphQL allows clients to request exactly what they need in a single query, no more and no less. This solves the problems of over-fetching (getting unnecessary data) and under-fetching (not getting enough data in one go). For example, consider a social media application. A user profile endpoint in REST might return a user's name and email, but to get the user's posts and their comments, you'd need to make separate API calls. In GraphQL, you can request the user's name, email, posts, and comments in one query, tailored to your frontend requirements. GraphQL's core design purpose is to give clients more power in describing their data needs, increase API efficiency, and enable better evolution of APIs over time without breaking clients.
