Generate rem for stylesheet and inject auto calculate scripts
A webpack plugin for generating rem for stylesheet and inject auto calculate scripts.
npm install pxtorem-webpack-plugin --save-dev
This plugin should be used with html-webpack-plugin
const HtmlWebpackPlugin = require('html-webpack-plugin');
const PxtoremWebpackPlugin = require('pxtorem-webpack-plugin');
module.exports = {
// ...
plugins: [
new HtmlWebpackPlugin({
filename: 'index.html',
template: './index.html',
}),
new PxtoremWebpackPlugin({
//
templates: [
'index.html'
],
baseWidth: 750,
baseDpr: 2,
remUnit: 10,
}),
],
// ...
}
This will generate a file dist/index.html containing the following:
<!DOCTYPE html>
<html lang="en">
<head>
<script>!function(e,t){var n=e.documentElement,i="orientationchange"in window?"orientationchange":"resize",d=function(){var e=n.clientWidth;n.style.fontSize=e/750*10+"px",n.setAttribute("data-dpr",Math.floor(window.devicePixelRatio))};d(),e.addEventListener&&t.addEventListener(i,d,!1)}(document,window);</script>
<meta charset="UTF-8">
<title>Vue webpack demo</title>
</head>
<body>
<div id="app"></div>
<script type="text/javascript" src="build.js"></script></body>
</html>
You can pass a hash of configuration options to html-webpack-plugin. Allowed values are as follows:
| Name | Type | Default | Description |
|---|---|---|---|
templates | {Array} | [] | The html files need to inject rem calculation scripts |
baseWidth | {Number} | 750 | The base width for UI design |
baseDpr | {Number} | 2 | base device pixel ratio |
remUnit | {Number} | 75 | rem unit value |
html root font-sizeBelow is the source code for injected scripts:
(function (doc, win) {
var docEl = doc.documentElement
var resizeEvent = 'orientationchange' in window ? 'orientationchange' : 'resize'
var recalcFun = function () {
var clientWidth = docEl.clientWidth
// baseWidth will be replace by `options.baseWidth`
// remUnit will be replace by `options.remUnit`
docEl.style.fontSize = remUnit * (clientWidth / baseWidth) + 'px'
// for dpr=2.xx -> 2, dpr=3.xx -> 3
docEl.setAttribute('data-dpr', Math.floor(window.devicePixelRatio))
}
recalcFun()
if (!doc.addEventListener) return
win.addEventListener(resizeEvent, recalcFun, false)
})(document, window)
If you want calculate px to rem more customized, and want to change the convert rules, you can refer to px2rem.scss
