Introduction to GraphQL
Learn the basics of GraphQL and how it can improve your API development experience.
GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. It provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need, and nothing more.
Benefits Over REST
Unlike REST APIs, GraphQL APIs allow clients to request exactly the data they need, avoiding over-fetching and under-fetching problems common with REST endpoints.
Setting Up a Basic GraphQL Server
Setting up a GraphQL server is straightforward with libraries like Apollo Server or Express GraphQL. You define a schema that specifies the types of data available and the queries clients can make.
Conclusion
GraphQL can greatly improve the flexibility and efficiency of your API development.
