 # react-graphql-client
 
-A simple GraphQL client for React applications. The library is not meant to be a production ready GraphQL client library. It hasn't powerful features such as caching or a global state. **But** it works and it should show that it's not too difficult to implement a GraphQL client library. You can look into the source code and the example application to see that there is not too much to it. If you feel the urge to build a sophisticated GraphQL client library (for React) on top of it, please do it! I encourage everyone to contribute to this ecosystem, because there should be more players in this field.

 Last but not least, there is a Mutation component analog to the Query component which is used to execute a mutation. However, in contrast to the Quert component, the Mutation component doesn't execute the mutation on render. You get an explicit callback function in the render prop child function for it.
