What is @types/relay-runtime?
@types/relay-runtime provides TypeScript type definitions for the relay-runtime library, which is a core part of Relay, a JavaScript framework for building data-driven React applications.
What are @types/relay-runtime's main functionalities?
Environment Configuration
This feature allows you to configure the Relay environment, which is essential for setting up the network layer and the store for managing GraphQL data.
const environment = new Environment({ network, store });
GraphQL Queries
This feature allows you to define GraphQL queries using the `graphql` tagged template literal, which is then used to fetch data from the GraphQL server.
const query = graphql`query AppQuery { viewer { id } }`;
Fragment Containers
This feature allows you to create fragment containers that specify the data requirements for a component, enabling Relay to fetch only the necessary data.
const MyComponent = createFragmentContainer(Component, { viewer: graphql`fragment MyComponent_viewer on Viewer { id }` });
Mutations
This feature allows you to commit mutations to the GraphQL server, enabling you to modify data and update the client-side store accordingly.
commitMutation(environment, { mutation, variables, onCompleted, onError });

Apollo Client is a comprehensive state management library for JavaScript that enables you to manage both local and remote data with GraphQL. It offers similar functionalities to relay-runtime but with a different approach to caching and state management.
urql
urql is a highly customizable and versatile GraphQL client for React that provides a simpler and more flexible alternative to relay-runtime. It focuses on ease of use and extensibility.
graphql-request
graphql-request is a minimal GraphQL client that allows you to send queries and mutations to a GraphQL server. It is much simpler than relay-runtime and does not include advanced features like caching or fragment containers.
