JavaScript Design Patterns

By: Hugo Di Francesco

Overview of this book

Unlock the potential of JavaScript design patterns, the foundation for development teams seeking structured and reusable solutions to common software development challenges in this guide to improving code maintainability, scalability, and performance. Discover how these patterns equip businesses with cleaner and more maintainable code, promote team collaboration, reduce errors, and save time and costs. This book provides a comprehensive view of design patterns in modern (ES6+) JavaScript with real-world examples of their deployment in professional settings. You’ll start by learning how to use creational, structural, and behavioral design patterns in idiomatic JavaScript, and then shift focus to the architecture and UI patterns. Here, you’ll learn how to apply patterns for libraries such as React and extend them further to general web frontend and micro frontend approaches. The last section of the book introduces and illustrates sets of performance and security patterns, including messaging and events, asset and JavaScript loading strategies, and asynchronous programming performance patterns. Throughout the book, examples featuring React and Next.js, in addition to JavaScript and Web API examples, will help you choose and implement proven design patterns across diverse web ecosystems, transforming the way you approach development.

Micro Frontends, Zones, and Islands Architectures

The micro frontend architecture, and specifically the “zones” and “islands” patterns, mirror the microservices architecture for backend systems. Given the right tooling, they allow multiple teams to maintain high-velocity development on a single product. The techniques covered in this chapter look at system-level interaction and integration patterns. Each system can leverage creational, structural, behavioral, and reactive view library patterns, as covered in Chapters 1, 2, 3, and 4 respectively. Micro frontend architectures help link systems together as opposed to structuring the code within each of them better.

We’ll cover the following topics in this chapter:

  • The problem space that micro frontends address, including some common approaches and their drawbacks
  • Leveraging Next.js features to build a “zones” micro frontend setup
  • Using the is-land package to deliver an...
