React Apollo Integration (Deprecated)

React Apollo (package `react-apollo`) provided the official React integration for Apollo Client, enabling developers to fetch and manage GraphQL data in React applications using Hooks, Components, and Higher-Order Components (HOCs). Version 3.1.5, released on April 14, 2020, was a stable release within the v3 series. The project has since been officially deprecated, with version 4.0.0 (released July 20, 2020) being its final release. All core React Apollo functionality, including hooks, components, HOCs, SSR, and testing utilities, has been migrated directly into the `@apollo/client` package (v3 and above). Developers are strongly advised to migrate to `@apollo/client` for active maintenance, new features, and bug fixes, as `react-apollo` no longer receives updates or support.
