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.

Design aspects involved


Before actually coding, we need to understand the how and why. Let's say if I have to cut down a tree (PS: I am a nature lover and I don't support this), instead of directly chopping it down, I would rather first sharpen the axe. We are going to do the same, sharpen our axe first. In this section, we are going to look at various aspects involved in designing microservices. We will look at what models of communication to go through, what is included in microservices, and what areas to take care of in order to achieve efficient microservice development. 

Microservice efficiency model 

Based on the various needs and requirements, we have defined a microservice efficiency model. Any proper implementation of microservices must adhere to it and provide a standard set of functionalities, as follows:

  • Communication over HTTP and HTTP listeners
  • Message or socket listeners
  • Storage capabilities
  • Proper business/technical capabilities definitions
  • Service endpoint definitions and communication...
