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.

Chapter 2. Gearing up for the Journey

After learning the theory about microservices, we will now move on to hands-on implementation. This chapter will lay the foundation for the journey ahead and will revisit Node.js and TypeScript concepts essential to the book. It will tell you about the trends and adoption rates of both languages. We will go through all the required installations, and we will prepare our development environment. We will test the development environment by implementing the customary Hello World microservice. In this chapter, we will focus on the following topics:

  • Setting up the primary development environment: We will set up a primary environment with all the prerequisites needed. We will understand all aspects required for microservice development.
  • Primer to TypeScript: In this section, we are going to walk through some of the major TypeScript topics that we are going to use throughout the book. We will justify usage of TypeScript as our language in Node.js, and understand...
