Node Cookbook - Third Edition

Overview of this book

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.

Setting up a development environment

Microservice systems have many advantages over traditional monolithic systems. However, this style of development does present its own challenges.

One of these has been termed Shell Hell. This occurs when we have many microservices to spin up and down on a local development machine in order to run integration and regression testing against the system, as illustrated in the following screenshot:

In this recipe, we're going to investigate a solution to this problem in the form of a microservice development environment.

Getting ready

Fuge is a toolkit written in Node.

It's designed specifically to help with local microservice development

Let's install Fuge with the following...
