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.

Reactive Manifesto


A reactive system is meant to be more loosely coupled, flexible, easy to migrate, and easily scalable on demand. These qualities make it easy to develop, gracefully handle faults, and react to errors. Errors are met with elegance rather than claustrophobic disasters. Reactive systems are effective and instantly respond, giving effective and interactive feedback to users. In order to summarize all the traits of a reactive system, the Reactive Manifesto was introduced. In this section, we'll look at the Reactive Manifesto and all the criteria needed. Now, let's look at what the Reactive Manifesto states.

Responsive systems

As part of responsive criteria, reactive systems always need to be responsive. They need to provide and respond to the user in a timely manner. This improves user experience, and we can handle errors in a better way. Any failure in the service should not propagate to the system, as it can cause a series of errors. A response is an essential thing. A failed...
