Overview of this book

Micro frontend is a web architecture for frontend development borrowed from the idea of microservices in software development, where each module of the frontend is developed and shipped in isolation to avoid complexity and a single point of failure for your frontend. Complete with hands-on tutorials, projects, and self-assessment questions, this easy-to-follow guide will take you through the patterns available for implementing a micro frontend solution. You’ll learn about micro frontends in general, the different architecture styles and their areas of use, how to prepare teams for the change to micro frontends, as well as how to adjust the UI design for scalability. Starting with the simplest variants of micro frontend architectures, the book progresses from static approaches to fully dynamic solutions that allow maximum scalability with faster release cycles. In the concluding chapters, you'll reinforce the knowledge you’ve gained by working on different case studies relating to micro frontends. By the end of this book, you'll be able to decide if and how micro frontends should be implemented to achieve scalability for your user interface (UI).

Knowledge sharing

Ideally, each micro frontend represents an isolated module, which works without dependencies and without any knowledge of the other micro frontends. Realistically, micro frontends will have dependencies and at least some knowledge of other micro frontends.

There are two kinds of references:

  • Direct (or strong) references leading to strong coupling
  • Indirect (or weak) references leading to loose coupling

Only loosely coupled modules can scale well. The problem with loosely coupled modules is that still some conventions and contracts need to be followed. For instance, if we emit an event with a certain name, potential listeners expect this name to remain the same. Once we change the name, the listeners cannot receive this event anymore.

The agreement for an identifier is what we refer to as knowledge sharing. There are multiple ways to perform the act of knowledge sharing:

  • Two or more teams agree on a certain name.
  • One team picks the...
