the file before compilation

// .js
import * as Utils from '@Aliases/utils/base';
require('@Aliases/utils/base')

// .(wxss|less|scss)
@import '@Aliases/style/reset.less';

.bg {
  background-image: url('@Aliases/images/32821027.jpg');
}

// .wxml
<import src="@Aliases/wxs/index.wxs" />

<image src="@Aliases/images/32821027.jpg" mode="cover"></image>

will become:

// .js
import * as Utils from 'path/to/your/folder/utils/base';
require('path/to/your/folder/utils/base')

// .(wxss|less|scss)
@import 'path/to/your/folder/style/reset.less';

.bg {
  background-image: url('path/to/your/folder/images/32821027.jpg');
}

// .wxml
<import src="path/to/your/folder/wxs/index.wxs" />

<image src="path/to/your/folder/images/32821027.jpg" mode="cover"></image>
