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.

What are reactive view library patterns?

Reactive view libraries are extensively used for JavaScript and web frontend development. A few very popular options are React, Angular, and Vue.

Reactive view libraries provide a way to write applications in a more scalable fashion by allowing the user interface (usually the browser) to react to changes in the data. Application development is, therefore, simplified, since the view library or framework takes care of all the direct manipulation necessary to maintain synchronization between the underlying data and the browser.

One of the key common denominators between these libraries and frameworks is the concept of a component, which contains business logic and/or rendering logic. The component is a key building block of an application. It can be reused or not, but it usually encapsulates a set of responsibilities and enforces interfaces around it.

A trait of components is that a developer should be able to use them as building blocks...
