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.

Primer to Node.js


Node.js has evolved over the years and has now become the go-to technology for anyone who wants to embrace microservices. Node.js was created to solve the massive I/O scaling problem, which when applied to our microservice design will result in a match made in heaven. The package manager for Node.js has more modules than Maven, RubyGems, and NuGet, which can be used directly and save lots of productive hours. Characteristics such as an asynchronous nature, event-driven I/O, and non-blocking mode make it one of the best solutions for creating high-end, efficient performance, real-time applications. When applied to microservices, it will be able to handle an extreme amount of load with low response times and low infrastructure. Let's look at one of the success stories of Node.js and microservices.

PayPal, seeing the trending Node.js, decided to go with Node.js in their accounts overview page. They were bewildered by the following results:
