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.

Service registry and discovery options


In this section, we will look at some of the commonly available options in the market for service discovery and registry. Options range right from low-level solutions providing a high degree of control to the architect (etcd from CoreOS and Consul from HashiCorp) to high-end solutions providing container scheduling solutions (Kubernetes from Google, Docker swarm, and so on). In this section, we will understand various options and look at the pros and cons of each.

Eureka

Eureka is a service registry and discovery framework outsourced by Netflix with a need for primary usage of locating services for the purpose of load balancing and failover for any middle-tier servers. In this section, we will look at service discovery and registry using Eureka.

The overall Eureka architecture consists of two components: the Eureka server and client. The Eureka server is a standalone server application that is responsible for:

  • Managing a registry of service instances
  • Providing...
