Professional GraphQL API Development Services
GraphQL is a modern API query language that provides clients with the power to request exactly the data they need, nothing more, nothing less. Unlike REST APIs, GraphQL uses a single endpoint with a strongly-typed schema, enables fetching multiple resources in one request, eliminates over-fetching and under-fetching, provides real-time updates with subscriptions, and offers excellent developer tooling. Our GraphQL specialists build flexible APIs that evolve without versioning, provide excellent performance, enable powerful developer experiences, and integrate seamlessly with modern frontend frameworks.
From new GraphQL APIs to GraphQL layers on existing REST APIs, we leverage Apollo Server, GraphQL Yoga, or custom implementations. Features include strongly-typed schemas with SDL, resolvers for efficient data fetching, DataLoader for batching and caching, authentication and authorization in resolvers, error handling with custom errors, subscriptions for real-time data, pagination with connections, field-level permissions, query complexity analysis, GraphQL Playground for testing, and monitoring with Apollo Studio. GraphQL simplifies frontend development and reduces bandwidth usage.
