Описание тега react-apollo
React Apollo allows you to fetch data from your GraphQL server and use it in building complex and reactive UIs using the React framework. React Apollo may be used in any context that React may be used. In the browser, in React Native, or in Node.js when you want to do server-side rendering.
react-apollo tag should be used for questions that are about the usage of the react-apollo ApolloClient container.
It should be included with the apollostack (and related) tags to clarify that this is the client wrapper being used.
It alleviates the need to use the reactjs, which should not be used, unless a person who knows nothing about react-apollo is likely to be able to answer the question.
