Comprehensive guide for building React applications with Apollo Client 4.x, covering queries, mutations, caching, and state management. Supports multiple React frameworks and setups: client-side apps (Vite, CRA), Next.js App Router with React Server Components, React Router 7 with streaming SSR, and TanStack Start Includes hooks for queries ( useQuery , useLazyQuery ), mutations ( useMutation ), and Suspense-based patterns ( useSuspenseQuery , useBackgroundQuery ) for modern React 18+ and 19...

Integrate REST APIs into GraphQL supergraphs using @source and @connect directives. Provides a structured 5-step process: research API structure, implement schema with directives, validate via rover supergraph compose , execute connectors, and test coverage Supports request configuration including headers, body payloads, batching for N+1 patterns, and environment variable injection via $env Handles response mapping with field selection, aliasing, sub-selections for nested data, and entity...

Apollo Federation enables composing multiple GraphQL APIs (subgraphs) into a unified supergraph.

Apollo iOS is a strongly-typed GraphQL client for Apple platforms. It generates Swift types from your GraphQL operations and schema, and ships an async/await client, a normalized cache (in-memory or SQLite-backed), a pluggable interceptor-based HTTP transport that handles queries, mutations, and multipart subscriptions, and an optional WebSocket transport ( graphql-transport-ws ) that can carry any operation type.

Apollo Kotlin is a strongly typed GraphQL client that generates Kotlin models from your GraphQL operations and schema, that can be used in Android, JVM, and Kotlin Multiplatform projects.

Connect AI agents to GraphQL APIs through the Model Context Protocol with built-in introspection and operation tools. Exposes GraphQL operations as MCP tools; supports three operation sources: local files, GraphOS Studio collections, and persisted query manifests Provides four introspection tools (introspect, search, validate, execute) for schema exploration and ad-hoc query testing; minification mode reduces token usage with compact notation Configurable authentication via static headers,...

Apollo Router is a high-performance graph router written in Rust for running Apollo Federation 2 supergraphs. It sits in front of your subgraphs and handles query planning, execution, and response composition.
