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.

Documenting


Documenting is a contract between thebackend and the frontend that takes care of dependency management between the two sides. If the API changes, the document needs to adapt to it quickly. One of the easiest fails in development can be the lack of visibility or lack of awareness about other people's work. Often, the traditional approach is to write service specification documents or use some static service registries that maintain different things. No matter how hard we try, documentation always goes out of date.

Need of Documentation

Documentation of development and organizational understanding of thesystem increases developers, skill and speed while dealing with two of the most common challenges that come with microservice adoption—technical and organizational change. The importance of thorough, updated documentation cannot be underestimated. Whenever we ask someone about problems they face while doing anything new, the answer is the same. We all face the same issue: we don't...
