Written by a skilled software engineer known for building enterprise-level apps with technologies like Nest.js, this book takes you through the core concepts, design patterns, and best practices needed to create scalable, high-performance applications with Nest.js, a cutting-edge Node.js framework.
The chapters help you get to grips with REST API and GraphQL implementations, harness the power of microservices, and explore real-world case studies, including e-commerce, social networking, and ERP systems. You’ll set up your development environment by utilizing TypeScript and npm and structuring projects effectively. You'll also learn to utilize Apollo Federation architecture to create efficient GraphQL APIs in Nest.js. This book offers hands-on guidance for testing and debugging APIs, handling exceptions, and validating data using pipes and guards, all while helping you build a complete Nest.js application from scratch.
By the end of this book, you'll be able to effectively adopt DevOps principles for continuous integration and deployment, as well as secure your Nest.js applications using advanced techniques.
