解决不支持引用css文件

yarn add @zeit/next-css
// next.config.js
const withCss = require('@zeit/next-css')
if (typeof require !== 'undefined') {
    require.extensions['.css'] = file => []
}
module.exports = withCss({})

antd 按需加载

yarn add antd
yarn add babel-plugin-import

// .babelrc
{
  "presets": ["next/babel"],
  "plugins": [
    [
      "import",
     {
       "libraryName": "antd"
     }
    ]
  ]
}
// page / _app.js
import App from 'next/app'
import 'antd/dist/antd.css'
export default App
