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.

Architecture design of our system 


In this section, we will look at the architectural aspects involved in distributed microservices. We will look at our overall architecture diagram, which we are going to make throughout the book, and look at aspects such as separating concerns, how to apply reactive patterns, and the microservice efficiency model. So, let's get started.

Now that we know our business requirements, let's design our architecture. Based on our knowledge of microservices and other concepts from Chapter 1Debunking Microservices, we have the final overall diagram, as shown here:

Microservice architecture

Note

We will study components such as API Gateway, service registry, and discovery in much more detail in later chapters. Here, they are just mentioned as part of the overall view.

Let's understand the key components in the preceding diagram to get a better idea of our architecture.

If we understood our business requirements correctly, we will come up with...
