+The [Apollo Client](https://github.com/apollographql/apollo-client) is a tool to efficiently work together with an GraphQL server. 
+It makes it easy to run your queries and mutations, cache results, brings tooling to download schemas and generate types to name a few of the useful features.

+GraphQL is a query language for your API, and a server-side runtime for executing queries by using a type system you define for your data. GraphQL isn't tied to any specific database or storage engine and is instead backed by your existing code and data.
+
+GraphQL was developed by Facebook around 2010 and releases 2015. 
+The main challenge it solves is to improve communication between browser and server on high dynamic web apps.
+
+The advantages are:
+* schema and schema validation together with a useful type system
+* the client (browser) controls what data should be send (data reduction)
+* whith one request you can fetch "all" required data
+
+We are using it together with [Apollo Client](/tools/apollo-client.html) in our [React.js](/languages-and-frameworks/react.html) based frontend.
+This way the React components have their relevant GraphQL snippet, defining what data they request or mutate from the "backend for frontend", directly coupled. 
+That makes it transparent what data is available. Apollo takes care of sending an aggregated GraphQL query to the backend.
+
+The framework [Flamingo offers support for GraphQL](https://docs.flamingo.me/3.%20Flamingo%20Modules/graphql.html) and also Flamingo Commerce offers a full featured GraphQL API for e-commerce features. ([Example GraphQL Console for Commerce](https://demoshop.flamingo.me/en/graphql-console))
