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.

Security checklist


Microservices development is a platform of standard tools combined with lots of supporting tools and everything is on the move. In this section, we will look at an overall checklist, which we can use to validate our development, or which can give us a general idea of our microservice development. 

Service necessities

The first and primary level of development is individual microservice development, satisfying some business capability. The following a checklist can be used while developing microservices:

  • Services should be developed and deployed independently
  • Services should not have shared data; they should have their own private data
  • Services should be small enough that they are focused and can add big value
  • Data should be stored in databases and service instances should not be stored
  • Work should be offloaded to asynchronous workers whenever possible
  • Load balancers should be introduced to distribute work
  • Security should be layered and we don't need to reinvent the wheel; for example...
