Over 60 high-quality recipes covering debugging, security, performance, microservices, web frameworks, databases, deployment and more; rewritten for Node.js 8, Node.js 6, and Node.js 4 About This Book * Actionable recipes across the full spectrum of Node.js development * Cutting edge techniques and tools for measuring and improving performance * Best practices for creating readily-scalable production systems Who This Book Is For If you have good knowledge of JavaScript and want to build fast, efficient, scalable client-server solutions, then this book is for you. Some experience with Node.js is assumed to get the most out of this book. If working from a beginner level Node Cookbook 2nd Edition is recommended as a primer for Node Cookbook 3rd Edition. What You Will Learn * Debug Node.js programs * Write and publish your own Node.js modules * Detailed coverage of Node.js core API's * Use web frameworks such as Express, Hapi and Koa for accelerated web application development * Apply Node.js streams for low-footprint data processing * Fast-track performance knowledge and optimization abilities * Persistence strategies, including database integrations with MongoDB, MySQL/MariaDB, Postgres, Redis, and LevelDB * Apply critical, essential security concepts * Use Node with best-of-breed deployment technologies: Docker, Kubernetes and AWS In Detail Today's web demands efficient real-time applications and scalability. Asynchronous event-driven programming is ideal for this, and this is where Node.js comes in. Server-side JavaScript has been here since the 90s, but Node got it right. With Node for tooling and server-side logic, and a browser-based client-side UI, everything is JavaScript. This leads to rapid, fluid development cycles. The full-stack, single language experience means less context-switching between languages for developers, architects and whole teams. This book shows you how to build fast, efficient, and scalable client-server solutions using the latest versions of Node. The book begins with debugging tips and tricks of the trade, and how to write your own modules. Then you'll learn the fundamentals of streams in Node.js, discover I/O control, and how to implement the different web protocols. You'll find recipes for integrating databases such as MongoDB, MySQL/MariaDB, Postgres, Redis, and LevelDB. We also cover the options for building web application with Express, Hapi and Koa. You will then learn about security essentials in Node.js and advanced optimization tools and techniques. By the end of the book you will have acquired the level of expertise to build production-ready and scalable Node.js systems. The techniques and skills you will learn in this book are based on the best practices developed by nearForm, one of the leaders in Node implementations, who supported the work of the authors on this book. Style and approach This recipe-based practical guide presents each topic with step-by-step instructions on how you can create fast and efficient server side applications using the latest features and capabilities in Node 8 whilst also supporting usage with Node 4 and 6.

In Node Cookbook Second Edition, each chapter focuses on a different aspect of working with Node. Following a Cookbook structure, the recipes are written in an easy to understand language. Readers will find it easier to grasp even the complex recipes which are backed by lots of illustrations, tips, and hints. If you have some knowledge of JavaScript and want to build fast, efficient, scalable client server solutions, then Node Cookbook Second Edition is for you. Knowledge of Node will be an advantage but is not required. Experienced users of Node will be able to improve their skills.

This is a new release of the original 1939 edition.

As part of Packt's cookbook series, this book is packed with practical recipes that will get you working efficiently with Node from the start. Each chapter focuses on a different aspect of working with Node. If you have some knowledge of JavaScript and want to build fast, efficient, scalable client-server solutions, then Node Cookbook is for you. Experienced users of Node will improve their skills although even if you have not worked with Node before, these practical recipes will make it easy to get started.
