react ts配置postcss-px-to-viewport

要在React TypeScript项目中配置postcss-px-to-viewport，你可以按照以下步骤进行操作：

1. 在项目根目录下找到craco.config.js文件。
2. 打开craco.config.js文件，并找到postcss插件的配置部分。
3. 将配置项修改为如下格式：

const pxToViewport = require('postcss-px-to-viewport-8-plugin');

module.exports = {
  style: {
    postcss: {
      mode: 'extends',
      loaderOptions: {
        postcssOptions: {
          ident: 'postcss',
          plugins: [
            pxToViewport({
              viewportWidth: 375, // 设置视口宽度，一般为设计稿宽度
            }),
          ],
        },
      },
    },
  },
};

这样配置后，postcss-px-to-viewport插件就会在构建过程中将像素(px)值转换为视口单位(vw)值，适配不同屏幕尺寸的设备。注意，你需要根据你的设计稿宽度来设置viewportWidth参数。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
