GraphQL is a query language for APIs and a server-side runtime developed by Facebook in 2012 and open-sourced in 2015. It has since become the go-to standard for teams building complex, data-intensive web applications that demand flexible, high-performance data access.
The graphql npm package now clears over 40 million weekly downloads, with the reference graphql-js implementation holding 20,000 GitHub stars.
Unlike REST, which forces clients to work around rigid, fixed endpoints, GraphQL lets clients request exactly the data they need - nothing more, nothing less. This precision eliminates over-fetching and under-fetching in a single stroke, reducing payload sizes, cutting unnecessary database load, and making your application dramatically faster.
At Dev and Deliver, GraphQL lives at the centre of our full-stack approach. On the backend, we build Apollo Server 4 and GraphQL Yoga APIs on Node.js, with schema-first or code-first design using NestJS's native GraphQL module and TypeGraphQL. On the frontend, we connect those APIs to Next.js applications using Apollo Client, fully integrated with the App Router and React Server Components. The result is a type-safe, end-to-end system where your data contract is defined once and trusted everywhere.
Whether you're migrating a legacy REST API, building a new SaaS product, or powering a headless CMS-driven website, GraphQL gives your team a scalable, maintainable architecture that grows with your business.
