Question

postCss 不适用于 Laravel 外的 laravel-mix、scss 和 tailwindcss

Cod*_*ver 3 npm postcss laravel-mix tailwind-css

我无法优化tailwindcss与postCss使用laravel-mix和Scss。该npm run dev生成正确的CSS。但是，生产构建npm run prod不会导出我在HTML模板中使用的类。

我试过没有purgecss ignore，这也没有任何区别。

/* purgecss start ignore */
@tailwind  base;
@tailwind  components;
/* purgecss end ignore */
@tailwind  utilities;
//@tailwind screens;

您可以将 PostCSS 插件传递到该sass方法中，如下面的代码示例所示。

// webpack.mix.js
let mix = require('laravel-mix');

mix
  .sass('assets/scss/app.scss', 'dist', {}, [
    require("tailwindcss"),
  ])
  .setPublicPath('web')
;
