GraphQL APIs with TypeScript: Efficient Back-end Development

GraphQL APIs with TypeScript: Efficient Back-end Development is the definitive guide for developers seeking to build robust, type-safe APIs that meet modern application demands. This comprehensive resource bridges the gap between GraphQL's flexible query language and TypeScript's powerful type system, creating a synergy that transforms backend development. In today's competitive tech landscape, APIs must be performant, scalable, and maintainable. This book demonstrates how combining TypeScript with GraphQL eliminates common runtime errors through compile-time checking, enhances developer experience with intelligent autocompletion, and ensures schema definitions remain consistent with implementation code. Starting with foundational concepts, readers progress through practical implementations of essential features including: Setting up optimal development environments for TypeScript-GraphQL projects Creating schema definitions using both SDL and decorator-based approaches Implementing type-safe resolvers with proper error handling Building comprehensive CRUD operations with Prisma integration Developing secure authentication and granular authorization systems Implementing efficient pagination, filtering, and sorting mechanisms Creating real-time applications with GraphQL subscriptions Testing GraphQL APIs thoroughly with TypeScript-aware tools Automating type generation with GraphQL Codegen Optimizing performance and implementing effective monitoring Deploying APIs to production with CI/CD pipelines What sets this book apart is its focus on TypeScript-specific patterns for GraphQL development. You'll learn how TypeGraphQL enables decorator-based schema definitions, how Prisma provides type-safe database operations, and how code generation keeps your types synchronized between schema and implementation. The book culminates with two complete project implementations—a Blog CMS API and an E-Commerce Backend—demonstrating how all concepts work together in real-world applications. Extensive appendices provide quick references for TypeScript developers working with GraphQL, ensuring you have practical resources for ongoing development. Whether you're a TypeScript developer expanding into GraphQL, a backend developer seeking to improve code quality, or a team lead architecting scalable API solutions, this book equips you with the knowledge to build better, more reliable APIs. Transform your development workflow and create GraphQL services that stand the test of time with "GraphQL APIs with TypeScript: Efficient Back-end Development."
