Frontend development has evolved a lot over the last decade. The web applications we are building today have to load quickly, run on a broad range of devices, and should react swiftly to user interactions. For a lot of businesses, the web frontend is the prime interaction surface for their users. So it’s natural to put a lot of thought and attention to detail into its development.

When your project is small, and you’re working with a handful of developers, building a nice web application is a straightforward task. However, if your business has a large web application and wants to improve and add new features continually, a single team will quickly be overwhelmed. This is where the micro frontend architecture comes in. There we slice the application into pieces that multiple teams can work on independently. In chapter 1, you’ll learn the core concepts, understand the reasoning behind this architecture, and know what types of projects can benefit the most from it. In the second chapter, we’ll jump right into the code and build a minimal viable micro frontends project from scratch: The Tractor Store. This e-commerce project functions as the basis for the more advanced techniques you’ll unlock later in the book.
