To use pug and stylus on the webpack template vue-cli

stylus.txt

To use pug and stylus on the webpack template vue-cli provides, simply run 

npm i --save-dev pug pug-loader stylus stylus-loader

Then add the attributes to the .vue root tags, eg:

<template lang="pug"></template>
<style lang="stylus"></style>.

I also had to add pug-plain-loader, so my line is

npm i --save-dev pug pug-loader pug-plain-loader stylus stylus-loader

You shouldn't need to install pug-loader, but will need the others.
