GraphQL API Development

Move beyond the limitations of REST. Learn to build efficient, strongly-typed APIs using GraphQL and Apollo Server to fetch exact data needs.

GraphQL revolutionizes data fetching by allowing clients to request exactly what they need, solving the over-fetching problem of REST. This course teaches you to design flexible schemas, write efficient resolvers, and manage the graph with Apollo Server. You will explore advanced topics like Federation for microservices, caching strategies, and securing your graph. Perfect for developers looking to modernize their API layer and improve frontend developer experience.
