In the last few years or so, microservices have achieved the rockstar status and are right now one of the most tangible solutions in enterprises to make quick, effective, and scalable applications. Microservices entail an architectural style and pattern in which a huge system is distributed into smaller services that are self-sufficient, autonomous, self-contained, and individually deployable.
The apparent rise of TypeScript and the long evolution from ES5 to ES6 has seen lots of big companies move to ES6 stack. TypeScript, due to its huge advantages like class and module supports, static type checking, and syntax similarity to JavaScript, has become the de facto solution for many enterprises. Node.js, due to its asynchronous, non-blocking, lightweight nature, and for, has been widely appointed by many companies. Node.js written in TypeScript opens doors to various opportunities.
However, microservices have their own difficulties to be dealt with, such as monitoring, scaling, distributing, and service discovery. The major challenge is deploying at scale, as we don't want to end up with system failures. Adopting microservices without actually knowing or addressing these issues would lead to a big issue. The most important part of this book concerns the pragmatic technological independence approach for dealing with microservices so as to leverage the best of everything.
In three parts, this book explains how these services work and the process to build any application the microservices way. You will encounter a design-based approach to architecture and guidance for implementing various microservices elements. You will get a set of recipes and practices for meeting practical, organizational, and cultural challenges to adoption. The goal of this book is to acquaint users with a practical, step-by-step approach for making reactive microservices at scale. This book will take readers into a deep dive with Node.js, TypeScript, Docker, Netflix OSS, and more. Readers of this book will understand how Node.js and TypeScript can be to deploy services that can run independently. Users will understand the evolving trend of serverless computing and the different Node.js capabilities, realizing the use of Docker for containerization. The user will learn how to autoscale the system using Kubernetes and AWS.
I am sure readers will enjoy each and every section of the book. Also, I believe this book adds value for not just Node.js developers but also others who want to play around with microservices and successfully implementing them in their businesses. Throughout this book, I have taken a practical approach by providing a number of examples, including a case study from the e-commerce domain. By the end of the book, you will have learned how to implement microservice architectures using Node.js, the TypeScript framework, and other utilities. These are battle-tested, robust tools for developing any microservice and are written to the latest specifications of Node.js.
