What is Webpack?
Webpack is a build tool that puts all of your assets, including Javascript, images, fonts, and CSS, in a dependency graph. Webpack lets you use require() in your source code to point to local files, like images, and decide how they're processed in your final Javascript bundle, like replacing the path with a URL pointing to a CDN.
Should I Use Webpack?
If you're building a complex Front End™ application with many non-code static assets such as CSS, images, fonts, etc, then yes, Webpack will give you great benefits.
If your application is fairly small, and you don't have many static assets and you only need to build one Javascript file to serve to the client, then Webpack might be more overhead than you need.
