Although deservedly popular and highly performant tools for building modern web applications, React and single-page applications (SPAs) become more and more sluggish as your applications and teams grow. To solve this problem, many large web apps have started to break down monolith SPAs into independently deployable smaller apps and components—a pattern called micro frontends. But micro frontends aren't a perfect solution, but rather a double-edged sword. This book teaches you how to architect and build them with the right principles to reap all the benefits without the pitfalls.This book will take you through two patterns of building micro frontends, the multi-SPA pattern and the micro apps pattern. You’ll find out which patterns to use and when, as well as take a look at the nuances of deploying these micro frontends using cloud-native technologies such as Kubernetes and Firebase. With the help of this book, you’ll gain an in-depth understanding of state management, solving problems with routing, and deployment strategies between the different micro frontends.By the end of this book, you’ll have learned how to design and build a React-based micro frontend application using module federation and deploy it to the cloud efficiently.
Building Microservices with Go. Develop seamless, efficient, and robust microservices with Go
Nic Jackson
Microservice architecture is sweeping the world as the de facto pattern to build web-based applications. Golang is a language particularly well suited to building them. Its strong community, encouragement of idiomatic style, and statically-linked binary artifacts make integrating it with other technologies and managing microservices at scale consistent and intuitive. This book will teach you the common patterns and practices, showing you how to apply these using the Go programming language.It will teach you the fundamental concepts of architectural design and RESTful communication, and show you patterns that provide manageable code that is supportable in development and at scale in production. We will provide you with examples on how to put these concepts and patterns into practice with Go. Whether you are planning a new application or working in an existing monolith, this book will explain and illustrate with practical examples how teams of all sizes can start solving problems with microservices. It will help you understand Docker and Docker-Compose and how it can be used to isolate microservice dependencies and build environments. We finish off by showing you various techniques to monitor, test, and secure your microservices. By the end, you will know the benefits of system resilience of a microservice and the advantages of Go stack.

Microservices is an architectural style that promotes the development of complex applications as a suite of small services based on business capabilities. This book will help you identify the appropriate service boundaries within the business. We'll start by looking at what microservices are, and what the main characteristics are. Moving forward, you will be introduced to real-life application scenarios, and after assessing the current issues, we will begin the journey of transforming this application by splitting it into a suite of microservices. You will identify the service boundaries, split the application into multiple microservices, and define the service contracts. You will find out how to configure, deploy, and monitor microservices, and configure scaling to allow the application to quickly adapt to increased demand in the future.With an introduction to the reactive microservices, you strategically gain further value to keep your code base simple, focusing on what is more important rather than the messy asynchronous calls.
