GraphQL is a query language for APIs and a runtime for executing those queries. It provides a more flexible and efficient alternative to REST.
GraphQL lets clients specify exactly what data they need, reducing over-fetching and under-fetching of data. It also provides a strongly typed schema and introspection capabilities.
query {
user(id: "1") {
name
email
posts {
title
published
}
}
}
GraphQL has a rich ecosystem, including Apollo, Relay, and GraphiQL for development and testing.
GraphQL is transforming how APIs are built and consumed. Its flexibility, strong typing, and developer tooling make it a compelling choice for modern web and mobile applications.
