webpack is a JavaScript module bundler that has taken the world by storm. As a webpack maintainer, I set out to ensure that we provided great documentation for first-time users. However, there is still much to be written about tapping into some of webpack’s most powerful features: custom plugins.

We will take a walk through the webpack source all the way down to its powerful AST parser. Along the way, we will learn about the anatomy of a webpack plugin, how webpack uses this system internally, and then implement a few plugins ourselves!!

My hope for you is that you’ll walk away able to write custom plugins, have a complete understanding of webpack from the inside-out, and leverage this powerful tool to work seamlessly with your tech stack and development workflow. Join me as we pop open the hood and master webpack together.
