What is GraphQL?
GraphQL is a query language for APIs developed by Facebook that allows clients to request exactly the data they need, reducing over-fetching and under-fetching of data.
GraphQL Explained
GraphQL is a query language and runtime for APIs that gives clients the power to request exactly the data they need—nothing more, nothing less. Developed by Facebook in 2012 and open-sourced in 2015, GraphQL solves the over-fetching and under-fetching problems common with REST APIs. Instead of multiple endpoints returning fixed data structures, GraphQL uses a single endpoint where clients specify their data requirements through queries. It features a strong type system, real-time subscriptions, and introspection capabilities. While GraphQL adds complexity compared to REST, it excels in scenarios with complex data relationships, mobile apps needing bandwidth efficiency, and applications with rapidly evolving frontend requirements.

Frequently Asked Questions
Should I use GraphQL or REST?
Use REST for simple CRUD APIs, public APIs, and when caching is critical. Use GraphQL for complex data relationships, mobile apps, and when different clients need different data shapes. Many companies use both.
Is GraphQL faster than REST?
GraphQL can be faster because clients fetch only needed data (less bandwidth). However, REST can be faster for simple queries due to HTTP caching. Performance depends more on implementation quality than the protocol.
Can GraphQL replace REST?
GraphQL can replace REST in many scenarios, but it's not always the better choice. REST remains ideal for simple APIs, file uploads, and webhook integrations. Consider your team's expertise and use case.
