Vue templates

[eltorio]

Hi,
Good idea to produce a mangling plugin for Vite.
I saw that you do not have a matching class list for vue templates.
In my Vue3 workflows I use this snippet, if it can help

// © Ronan LE MEILLAT

import fs from "fs";

function getSetOfClasses(data:string):string[]{
    const regExp = new RegExp(/(?:class)=(?:["']\W+\s*(?:\w+)\()?["']([^'"]+)['"]/g)
    const tresult = [] as string[]
    for (const match of data.matchAll(regExp)){
        const noNewLine = match[1].replace(new RegExp(/\n/g),' ')
        const noMultipleSpace = noNewLine.replace(new RegExp(/\s\s+/g), ' ')
        const arrayOfSingleClasses = noMultipleSpace.trim().split(' ')
        tresult.push(...arrayOfSingleClasses)
    }
    return [...new Set(tresult)]
}
const data = fs.readFileSync('./src/components/forms/EmailForm.vue').toString()
console.log (getSetOfClasses(data))

this gives me this array
