After you get started, check out the full Apollo Client documentation in the navigation on the left.
We recommend the following articles in particular:
- Queries and Mutations. These are the read and write operations of GraphQL.
- Caching overview. Apollo Client's normalized cache enables you to skip network requests entirely when data is already available locally.
- Managing local state. Apollo Client provides APIs for managing both remote and local data, enabling you to consolidate all of your application's state.
- Basic HTTP networking. Learn how to send custom headers and other authentication metadata in your queries.
- Testing React components. Test your GraphQL operations without requiring a connection to a server.
This documentation set focuses on React, but Apollo Client supports many other libraries and languages:
