GraphQL local state management with Apollo

GraphQL is a versatile data query language that offers a single endpoint for CRUD operations on APIs, contrasting with the multiple endpoints of REST APIs, thus providing more flexibility for frontend developers who can specify exactly what data is needed. This tutorial guides users through setting up a GraphQL API in Node.js and integrating it with a React application using the Apollo Client library, which manages state data locally and facilitates GraphQL-frontend integration. The tutorial covers creating schemas with queries and mutations for managing fake user data, setting up a GraphQL server with Express, and using GraphiQL for testing API calls. It also explains how to connect the GraphQL backend to a React frontend, using Apollo Client to fetch and display user data or perform data mutations. Additionally, the tutorial highlights the importance of monitoring GraphQL requests in production using tools like LogRocket, which offers session replay and error tracking to ensure reliable API performance.
