React GraphQL Mutation

The major use of GraphQL is to fetch data. However, there are always two sides to such an interface: read and write. That’s where GraphQL mutations complement the interface. Previously, you learned about GraphQL mutations using GraphQL without React. In this section, you will implement such a mutation in your React GraphQL application.

addStar Mutation

We have executed GitHub’s addStar mutation before in GraphQL. Now, let’s implement this mutation in React. Before implementing the mutation, you should query additional information about the repository, which is partially required to star the repository in a mutation.
