TypeScript Microservices

Overview of this book

In the last few years or so, microservices have achieved the rock star status and right now are one of the most tangible solutions in enterprises to make quick, effective, and scalable applications. The apparent rise of Typescript and long evolution from ES5 to ES6 has seen lots of big companies move to ES6 stack. If you want to learn how to leverage the power of microservices to build robust architecture using reactive programming and Typescript in Node.js, then this book is for you. Typescript Microservices is an end-to-end guide that shows you the implementation of microservices from scratch; right from starting the project to hardening and securing your services. We will begin with a brief introduction to microservices before learning to break your monolith applications into microservices. From here, you will learn reactive programming patterns and how to build APIs for microservices. The next set of topics will take you through the microservice architecture with TypeScript and communication between services. Further, you will learn to test and deploy your TypeScript microservices using the latest tools and implement continuous integration. Finally, you will learn to secure and harden your microservice. By the end of the book, you will be able to build production-ready, scalable, and maintainable microservices using Node.js and Typescript.

Being reactive in Node.js


Now that we have gone through the concepts of reactive programming and advantages of reactive programming in microservices, let's now look at some practical implementations of reactive programming in Node.js. In this section, we will understand the building blocks of reactive programming by seeing implementations of reactive programming in Node.js.

Rx.js

This is one of the most trending libraries and it is actively maintained. This library is available for most programming languages in different forms such as RxJava, RxJS, Rx.Net, RxScala, RxClojure, and so on. At the time of writing, it had more than 40 lakh downloads in the last month. Besides this, a huge amount of documentation and online support is available for this. We will be using this library most of the time, except when the need arises. You can check this out at: http://reactivex.io/. At the time of writing, the stable version of Rx.js was 5.5.6. Rx.js has lots of operators. We can use the Rx.js operators...
