It's not the easiest tool to learn due to its configuration-driven approach, but it's incredibly powerful. The purpose of this guide is to help you get started with webpack and then go beyond the basics.
Webpack isn’t the only available bundler, and a collection of different tools have emerged. Task runners, such as Grunt and Gulp, are good examples of higher-level tools. Often the problem is that you need to write the workflows by hand. Pushing that issue to a bundler, such as webpack, is a step forward.
Webpack takes another route. It allows you to treat your project as a dependency graph. You could have an index.js in your project that pulls in the dependencies the project needs through the standard
import statements. You can refer to your style files and other assets the same way if you want.
Webpack does all the preprocessing for you and gives you the bundles you specify through configuration and your code. This declarative approach is versatile, but it's difficult to learn.
Webpack becomes an indispensable tool after you begin to understand how it works. This book has been designed to get through that initial learning curve and even go further.
This book has been designed to complement the official documentation of webpack. This book can be considered a companion to it. This book has been designed to get through that initial learning curve and go even further.
The book teaches you to develop a composable webpack configuration for both development and production purposes. Advanced techniques covered by the book allow you to get the most out of webpack 4.
The book starts by explaining what webpack is. After that, you will find multiple chapters that discuss webpack from a different viewpoint. As you go through these chapters, you will develop your own webpack configuration while at the same time learning essential techniques.
The book has been split into the following parts:
Finally, there is a short conclusion chapter that recaps the main points of the book. It contains checklists of techniques from this book that allow you to methodically go through your projects.
The appendices at the end of the book cover secondary topics and sometimes dig deeper into the main ones. You can approach them in any order you want depending on your interest.
The Troubleshooting appendix at the end covers what to do when webpack gives you an error. It covers a process, so you know what to do and how to debug the problem. When in doubt, study the appendix. If you are unsure of a term and its meaning, see the Glossary at the end of the book.
If you don’t know much about the topic, consider going carefully through the early parts. You can scan the rest to pick the bits you find worthwhile. If you know webpack already, skim and choose the techniques you find valuable.
In case you know webpack well already, there is still something in the book for you. Skim through it and see if you can pick up new techniques. Especially read the summaries at the end of the chapters and the concluding chapter of the book.
Given this book receives a fair amount of maintenance and improvements due to the pace of innovation, there's a versioning scheme in place. Release notes for each new version are maintained at the book blog. You can also use GitHub compare tool for this purpose. Example:
The page shows you the individual commits that went to the project between the given version range. You can also see the lines that have changed in the book.
The current version of the book is 2.3.1.

Big thanks to Christian Alfoni for helping me craft the first version of this book. This is what inspired the entire SurviveJS effort. The version you see now is a complete rewrite.
This book wouldn’t have been possible without the original "SurviveJS - Webpack and React" effort. Anyone who contributed to it deserves my thanks. You can check that book for more accurate attributions.
