Vue3 + Ts + Vite mobile terminal adaptation tutorial -- easy to get started

Target:

Different screens will appear on some models, so the adaptation scheme is used to adapt the mobile terminal project, and the plug-in method is introduced here as an example.

Use process:

1. Downloading two plug-in dependencies
   cnpm/ npm / yarn install [email protected] --save-dev requires a specified version, otherwise errors may occur! ! !
   cnpm/ npm / yarn install lib-flexible --save

2. Create a postcss.config.js file in the root directory, and write the following code, just copy it directly.
   

module.exports = {
    
    
  plugins: {
    
    
    'postcss-pxtorem': {
    
    
      rootValue: 37.5,
      // 根字体大小是 37.5
      propList: ['*'],
      selectorBlackList: ['.no__rem']
      // 过滤掉.no__rem-开头的class，不进行rem转换处理
    }
  }
}

3. Create a new rem.js file in the tool class file

// 设置基础根文件大小
let baseSize = 37.5
// rem 函数
function setRem () {
    
    
  // 设计稿一般都是以375的宽度
  const scale = document.documentElement.clientWidth / 375
  // 设置页面根节点字体大小（“Math.min(scale, 2)” 指最高放大比例为2，可根据实际业务需求调整）
  document.documentElement.style.fontSize = baseSize * Math.min(scale, 2) + 'px'
}
// 调用方法
setRem()

// 监听窗口在变化时重新设置跟文件大小
window.onresize = function () {
    
    
  setRem()
}

4. Introduce the rem, js method in the main.ts file

import './utils/rem'

5. You're done! Automatically convert px units to rem units.
