Nested Mutation Graphql Apollo

Finally, steps 1-5 are processed for any additional binding configurations provided in bindings and the resulting typeDefs and resolvers are merged and provided to Apollo Server. The mutation is called “informationRegisterForThread”. Usually, GraphQL’s mutations are triggered imperatively, but that’s only because a HOC or render prop grants access to the function which executes the mutation (e. One particular type of mutation is operations that change users, like signing up a new user. That data fetch itself could be a graphQL query. The workflow when working with a GraphQL endpoint and the Apollo SDK is as follows: Use the Apollo CLI to introspect the GraphQL schema for your content model and include it in your project.
