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 best practices for individual services/applications


A microservice architecture shifts around complexity. Instead of having a single very complicated system, there are a bunch of simple services with complicated interactions. Our goal is to make sure that complexity stays in check and within boundaries. Security is really hard to get right. There are countless ways to break into an application. Node.js is no different. In this section, we are going to look at the techniques to prevent security vulnerabilities. This section is meant to act as a basic checklist to ensure that our microservice addresses some of the biggest security threats. So, let's get started.

Checking for known security vulnerabilities

Due to a wealth of modules available in npm, we can directly work on the application and rely on the ecosystem for ready-made solutions. However, due to the huge modules, larger security vulnerabilities can occur at any time even for mature popular frameworks. In this section, we will...
