复制代码1️⃣ 项目初始 + 暴露配置项
- 1、create-react-app react-vw-layout 初始化项目
- 2、npm run eject 暴露配置项
2️⃣ postCss插件安装配置
package.json 中添加依赖,并安装
"postcss-aspect-ratio-mini": "0.0.2",
//--坑点 已经更新 postcss-preset-env 所以请使用 "postcss-preset-env": "6.0.6"?
"postcss-cssnext": "^3.1.0",
"postcss-flexbugs-fixes": "3.2.0",
"postcss-loader": "2.0.8",
"postcss-px-to-viewport": "0.0.3",
"postcss-viewport-units": "^0.1.4",
"postcss-write-svg": "^3.0.1"
复制代码config/webpack.config.dev.js 文件中修改添加配置（开发环境生效） (生产环境打包配置如下，也是一样的在文件夹 config/webpack.config.prod 中修改)
// config/webpack.config.dev.js
// 文件头部引进依赖
const fs = require('fs');
const path = require('path');
const resolve = require('resolve');
const webpack = require('webpack');
const PnpWebpackPlugin = require('pnp-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CaseSensitivePathsPlugin = require('case-sensitive-paths-webpack-plugin');
const InterpolateHtmlPlugin = require('react-dev-utils/InterpolateHtmlPlugin');
const WatchMissingNodeModulesPlugin = require('react-dev-utils/WatchMissingNodeModulesPlugin');
const ModuleScopePlugin = require('react-dev-utils/ModuleScopePlugin');
const getCSSModuleLocalIdent = require('react-dev-utils/getCSSModuleLocalIdent');
const getClientEnvironment = require('./env');
const paths = require('./paths');
const ManifestPlugin = require('webpack-manifest-plugin');
const ModuleNotFoundPlugin = require('react-dev-utils/ModuleNotFoundPlugin');
const ForkTsCheckerWebpackPlugin = require('fork-ts-checker-webpack-plugin-alt');
const typescriptFormatter = require('react-dev-utils/typescriptFormatter');
// 移动端适配添加 - 插入
const postcssAspectRatioMini = require('postcss-aspect-ratio-mini');
const postcssPxToViewport = require('postcss-px-to-viewport');
const postcssWriteSvg = require('postcss-write-svg');
const postcssCssnext = require('postcss-preset-env'); //这个插件已经更新 postcss-preset-env 所以请使用 "postcss-preset-env": "6.0.6",
const postcssViewportUnits = require('postcss-viewport-units');
const cssnano = require('cssnano');
//配置项中添加使用
{
// Options for PostCSS as we reference these options twice
// Adds vendor prefixing based on your specified browser support in
// package.json
loader: require.resolve('postcss-loader'),
options: {
// Necessary for external CSS imports to work
// https://github.com/facebook/create-react-app/issues/2677
ident: 'postcss',
plugins: () => [
require('postcss-flexbugs-fixes'),
require('postcss-preset-env')({
autoprefixer: {
flexbox: 'no-2009',
},
stage: 3,
}),
// -----插入适配移动端配置项-----?
postcssAspectRatioMini({}),
postcssPxToViewport({
viewportWidth: 750, // (Number) The width of the viewport.
viewportHeight: 1334, // (Number) The height of the viewport.
unitPrecision: 3, // (Number) The decimal numbers to allow the REM units to grow to.
viewportUnit: 'vw', // (String) Expected units.
selectorBlackList: ['.ignore', '.hairlines'], // (Array) The selectors to ignore and leave as px.
minPixelValue: 1, // (Number) Set the minimum pixel value to replace.
mediaQuery: false // (Boolean) Allow px to be converted in media queries.
}),
postcssWriteSvg({
utf8: false
}),
postcssCssnext({}),
postcssViewportUnits({}),
cssnano({
//旧的 --坑点
// preset: "advanced",
// autoprefixer: false,
// "postcss-zindex": false
//新配置继续使用高级配置,按照这个配置
"cssnano-preset-advanced": {
zindex: false,
autoprefixer: false
},
})
],
},
},
复制代码3️⃣测试验证
修改 App.css 文件
.App {
width: 750px;
height: 300px;
background: #409eff;
color: #ffffff;
line-height: 200px;
text-align: center;
}
复制代码npm start 启动项目，打开控制台，这个时候已经生效了
配置好生产环境之后验证,npm run build,这个时候，生产打包已经生效了。
4️⃣ 一些兼兼容性hacks处理
修改 public/index.html, 引入阿里的 cdn
<script src="//g.alicdn.com/fdilab/lib3rd/viewport-units-buggyfill/0.6.2/??viewport-units-buggyfill.hacks.min.js,viewport-units-buggyfill.min.js">script>
<script>
window.onload = function() {
window.viewportUnitsBuggyfill.init({
hacks: window.viewportUnitsBuggyfillHacks
});
// 验证输出
const winDPI = window.devicePixelRatio;
const uAgent = window.navigator.userAgent;
const screenHeight = window.screen.height;
const screenWidth = window.screen.width;
const winWidth = window.innerWidth;
const winHeight = window.innerHeight;
console.log(winDPI, "设备 DPI");
console.log(uAgent, "客户端");
console.log(screenWidth, "屏幕宽度");
console.log(winHeight, "屏幕高度");
console.log(winWidth, "Windows Width");
console.log(winHeight, "Windows Height");
};
script>
复制代码至此配置算是完成了,更多其中插件的配置,还需要了解一下官方的配置使用,此外插件和可行性方案都会更新,这里只是作为自己学习实际的一个可行性方案实践的过程,如果有更多更新方案可以留言告知。谢阅~
