Vue.js is a versatile and approachable framework for building modern JavaScript applications. You can start out by simply adding a script tag with some vanilla JS. Or you can go all-in and create a modern JavaScript application with all the trimmings using a build system such as Webpack.

The canonical way to build & bundle a Vue.js application is with webpack, and indeed, pretty much everything Vue-related assumes that you’ll be using webpack. However, you don’t have to. You could use Vue.js without build tooling, or you could use an alternative module bundler.
