Node.js GraphQL for Subscriptions : Implementing Real-Time Data with Resolvers and Schemas for Dynamic Apps

Revolutionize your backend development and deliver lightning-fast, real-time experiences with Node.js GraphQL for Subscriptions: Implementing Real-Time Data with Resolvers and Schemas for Dynamic Apps by expert Riches Wren. In a world where users demand instant updates—from live chats and stock tickers to collaborative tools—this practical guide unlocks the full potential of GraphQL subscriptions in Node.js, transforming static APIs into dynamic, event-driven powerhouses that keep your apps alive and engaging.
Overwhelmed by polling inefficiencies, WebSocket complexities, or scaling real-time features? This book cuts through the noise, equipping you with step-by-step strategies to build robust, performant systems. Drawing on industry insights, Wren starts with foundations: the shift from REST to GraphQL, Node.js setup, basic schemas, resolvers, and data integration. Master subscriptions with deep dives into Pub/Sub mechanisms, AsyncIterators, event triggering, filtering, and security. Craft advanced schemas using types, unions, stitching, and federation; optimize for performance with throttling, caching, monitoring, and load testing; and secure your apps against vulnerabilities while ensuring GDPR compliance.
Elevate your skills through hands-on projects and exercises: construct a real-time chat app with presence detection, a stock price dashboard, IoT data streaming, and more. Explore frontend integrations with Apollo Client, React, and React Native for seamless UI updates; deploy to clouds like AWS and Vercel with Docker and CI/CD; and glimpse future trends like HTTP/3 and TypeScript ORMs. Each chapter includes quizzes, key takeaways, code snippets, and a companion repository for resources, making learning interactive and immediately applicable.
Ideal for Node.js developers, full-stack engineers, or API architects with basic JavaScript knowledge seeking to conquer real-time challenges. Whether you're enhancing social feeds, building collaborative platforms, or innovating in IoT, this book provides the tools to create scalable, secure apps that wow users.
