Building Your Own JavaScript Framework. Architect extensible and reusable framework systems

Vlad Filippov, Mike Taylor

JavaScript frameworks play an essential role in web application development; however, no single framework works perfectly for all projects. This book will help you understand existing projects, design new software architecture, and maintain projects as they grow. You’ll go through software architecture principles with JavaScript, along with a guided example of structuring your project and maintenance guidance.This book covers framework planning aspects, enabling you to identify key stakeholders, understand JavaScript API design, and leverage complex abstraction. The second part of the book takes a practical programming approach to building your own framework by showing you how to structure modules and interfaces. As you advance, you’ll discover how to develop data-binding components, work with JavaScript APIs, and much more. While writing a framework is half the job, continuing to develop it requires effort from everyone involved. The concluding chapters help to achieve this by teaching you the crucial aspects of software maintenance and highlighting the constants of framework development.By the end of this book, you’ll have gained a clear understanding of the JavaScript framework landscape, along with the ability to build frameworks for your use cases.
