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.

Summary


In this chapter, we went through our hardening layer. We looked at all the vulnerabilities our service is exposed to, and we learned about how to address them. We looked at some fundamentals, such as rate limiting, session handling, how to prevent parameter pollution, and more. We got acquainted with security at the container level and went through all the best practices for handling microservice security before moving on to scalability. We looked at Kubernetes and the Amazon load balancer, and got hands-on with both.

So far, you have learned how to build microservices using TpeScript on the Node.js platform and learned about all the aspects of microservice development, right from developing, the API Gateway, service registry, discovery, inter-service communication, Swagger, deployment, and testing. The objective of the book was to give you a practical hands-on guide to the microservice development and an understanding of the basic aspects to get you up and running. I really hope...
