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).

Advantages and disadvantages

To cover the advantages and disadvantages of this pattern, we need to look at its close companion: server-side composition. If done correctly, then edge-side composition will be much more lightweight and allow us to do things such as caching. This gives websites a great performance boost, without us requiring more sophisticated algorithms or tricks.

One of the reasons why even a non-cached response may be faster with edge-side composition is that fragments are supposed to be flat. In the previous pattern, we were not only able to utilize nested fragments, but were actually encouraged to do exactly that. But even a non-flat structure can be flattened by using a simple trick. We'll illustrate this by using code.

Let's say we start with a structure like this:

// index.html (original)
<esi:include src="http://example.com/fragment1.html" />
// fragment1.html
<esi:include src="http://example.com/fragment2.html"...
