GraphQL API Development
About this offering
Develop flexible, efficient GraphQL APIs that give clients exactly the data they need with powerful query capabilities. I build GraphQL servers with proper schema design, resolver optimization, and real-time subscriptions. Perfect for applications with complex data requirements, multiple clients, or need for flexible data fetching. GraphQL reduces over-fetching, enables rapid frontend development, and provides excellent developer experience. You'll receive a complete GraphQL server with schema documentation, authentication, authorization, caching strategies, and monitoring. I ensure your API is performant, secure, and easy to work with for frontend developers.

How it works
Frequently Asked Questions
What are the benefits of GraphQL over REST APIs?
GraphQL eliminates over-fetching and under-fetching of data, enables clients to request exactly what they need, provides strong typing, supports real-time subscriptions, and offers better developer experience.
How long does GraphQL API development take?
GraphQL API development typically takes 5-10 weeks including schema design, resolver implementation, authentication, optimization, and documentation. Timeline depends on data complexity and features.
Can you migrate existing REST APIs to GraphQL?
Yes, we can gradually migrate REST APIs to GraphQL, allowing both to coexist during transition. We wrap existing REST endpoints or rebuild queries directly against your database.
Does GraphQL support real-time data?
Yes, GraphQL supports real-time updates through subscriptions using WebSockets. Clients can subscribe to data changes and receive instant updates when data changes on the server.
How do you optimize GraphQL performance?
We implement DataLoader for batching and caching, query complexity analysis to prevent expensive queries, pagination, depth limiting, and database query optimization to ensure high performance.
Is GraphQL secure?
Yes, we implement authentication, field-level authorization, query depth limiting, query cost analysis, rate limiting, and input validation to secure GraphQL APIs against common vulnerabilities.
How much does GraphQL API development cost?
GraphQL API development ranges from $3,000 to $18,000 depending on schema complexity, number of types and queries, authentication requirements, and optimization needs.
