uni-app配置tailwindcss

uni-app配置tailwindcss

前置： 脚手架创建的uniapp项目，vscode执行，vue3版本。
按照以下步骤，就可以在uniapp项目中使用呢tailwind了。

1. pnpm install -D tailwindcss postcss autoprefixer

2. npx tailwindcss init -p

3. 在 tailwind.config.js 中写入

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: ['./index.html', './src/**/*.{js,ts,jsx,tsx,vue}'],
  theme: {
    extend: {},
  },
  plugins: [],
} 复制

4. 在App.vue中添加

<style>
  @import 'tailwindcss/base';
  @import 'tailwindcss/components';
  @import 'tailwindcss/utilities';
</style>复制

5. 在vite.config.js中修改

import { defineConfig } from "vite";
import tailwindcss from 'tailwindcss';
import uni from "@dcloudio/vite-plugin-uni";
 
export default defineConfig({
  css: {
    postcss: {
      plugins: [
        tailwindcss(),
      ],
    },
  },
  plugins: [uni()],
});复制

6. 小程序适配 pnpm i @uni-helper/vite-plugin-uni-tailwind

// vite.config.js
import { defineConfig } from "vite";
import tailwindcss from 'tailwindcss';
import uni from "@dcloudio/vite-plugin-uni";
import uniTailwind from '@uni-helper/vite-plugin-uni-tailwind';
 
export default defineConfig({
  css: {
    postcss: {
      plugins: [
        tailwindcss(),
      ],
    },
  },
  plugins: [uni(), uniTailwind()],
});复制

7.rem to rpx,由于tailwind默认是rem单位，需要转到rpx

pnpm i tailwindcss-rem2px-preset -D

//tailwind.config.js
/** @type {import('tailwindcss').Config} */
module.exports = {
  content: ['./index.html', './src/**/*.{js,ts,jsx,tsx,vue}'],
  theme: {
    extend: {},
  },
  plugins: [],
  presets: [
    require('tailwindcss-rem2px-preset').createPreset({
      // 32 意味着 1rem = 32rpx
      fontSize: 32,
      // 转化的单位,可以变成 px / rpx
      unit: 'rpx'
    })
  ],
}复制
