Mpx

安装

npm

npm install -D tailwindcss @tailwindcss/postcss postcss weapp-tailwindcss

Yarn

yarn add --dev tailwindcss @tailwindcss/postcss postcss weapp-tailwindcss

pnpm

pnpm add -D tailwindcss @tailwindcss/postcss postcss weapp-tailwindcss

然后把下列脚本，添加进你的 package.json 的 scripts 字段里:

package.json

 "scripts": {
   "postinstall": "weapp-tw patch"
 }

这是为了给 tailwindcss@4 打上支持 rpx 单位的补丁，否则它会把 rpx 认为是一种颜色

配置

更改 mpx.config.js 注册 weapp-tailwindcss

mpx.config.js

const { defineConfig } = require('@vue/cli-service')
const { UnifiedWebpackPluginV5 } = require('weapp-tailwindcss/webpack')
module.exports = defineConfig({
  outputDir: `dist/${process.env.MPX_CURRENT_TARGET_MODE}`,
  pluginOptions: {
    mpx: {
      plugin: {
        srcMode: 'wx',
        hackResolveBuildDependencies: ({ files, resolveDependencies }) => {
          const path = require('path')
          const packageJSONPath = path.resolve('package.json')
          if (files.has(packageJSONPath)) files.delete(packageJSONPath)
          if (resolveDependencies.files.has(packageJSONPath)) {
            resolveDependencies.files.delete(packageJSONPath)
          }
        }
      },
      loader: {}
    }
  },
  configureWebpack(config) {
    // 添加的代码在这里
    config.plugins.push(
      new UnifiedWebpackPluginV5({
        rem2rpx: true,
        appType: 'mpx'
      })
    )
  }
})

添加 postcss.config.js 注册 @tailwindcss/postcss

postcss.config.js

module.exports = {
  plugins: [
    require('@tailwindcss/postcss')()
  ]
}

添加样式

在项目目录下，小程序全局的 app.mpx 中，添加以下内容：

app.mpx

<style>
@import "weapp-tailwindcss";
</style>

更改好配置之后，直接启动即可
