Apollo is a framework designed to make it easy for developers to use GraphQL in their applications, regardless of the frontend or backend technology being used. It provides a caching JavaScript client for GraphQL, React Apollo for integrating GraphQL data into React applications, and server-side tools that implement the core GraphQL functionality. Apollo Client is built on top of Redux, making it easy to integrate with existing Redux stores. The framework includes features such as server-side rendering, which allows developers to easily render components on the server, and performance optimization techniques. Future plans for Apollo include developing sugar-on-top features, improving performance, and building developer tools to help users understand their app's data. GraphQL is an incrementally adoptable technology that can be added to existing REST API database implementations, allowing developers to continue using their existing backend without rewriting it.
