Everytime I update my css or js files in infoweb\menu\module\assets, I have to empty the backend\web\assets folder

If you enviroment is production I recommend to use Cache Busting:
如果您的环境是生产环境，我建议使用Cache Busting：
return [
// ...
'components' => [
'assetManager' => [
'appendTimestamp' => true,
],
],
];
for more information about assets, read the Assets Yii2 documentation.

If you are developing your own plugin, you can force publish assets per bundle (note: $sourcePath should be set)
如果你正在开发自己的插件，你可以强制每个包发布资产（注意：$sourcePath 应该被设置）
<?php
namespace app\components\forms\redactorAssets;
use yii\web\AssetBundle;
class RedactorCutAsset extends AssetBundle {
public $sourcePath = '@app/components/forms/redactorAssets/assets';
public $js = [
'cut.js',
];
public $publishOptions = [
'forceCopy'=>true,
];
}

sudo rm -rf frontend/web/assets/*
sudo chmod 777 frontend/web/assets
./yii cache/flush-all
If this does not work:
如果这不起作用：

I use CClientScript::registerScriptFilemethod in my view files:
我CClientScript::registerScriptFile在视图文件中使用方法：
Yii::app()->clientScript->registerScriptFile(
$this->getAssetsBase() . '/js/script.js'
);
If I modified script.js, after next page reload I will see all changes
如果我修改了 script.js，在下一页重新加载后，我将看到所有更改
For css files - CClientScript::registerCssFile
对于 css 文件 - CClientScript::registerCssFile
Yii::app()->clientScript->registerCssFile(
$this->getAssetsBase() . '/css/style.css'
);
UPDATE: if you use yii 2.0 beta, you can read some information about changes in mechanic of client helpers here: link
更新：如果您使用 yii 2.0 beta，您可以在此处阅读有关客户端助手机制更改的一些信息： link

The AssetManager will create a hash based on the file modification time. The modification time of a directory does not change when any file is changed.
If you have an AssetBundle that has a directory as $sourcePath, the modification time of the directory is used, the hash will not change, and nothing gets copied to the web/assetsdirectory.
AssetManager 将根据文件修改时间创建一个哈希值。修改任何文件时，目录的修改时间不会改变。如果您的 AssetBundle 的目录为 as $sourcePath，则使用目录的修改时间，哈希不会更改，并且不会将任何内容复制到web/assets目录中。
I suggest overriding AssetManager::hash()in a subclass or write a function for AssetManager::$hashCallback:
我建议AssetManager::hash()在子类中覆盖或编写一个函数AssetManager::$hashCallback：
'components' => [
'assetManager' => [
'hashCallback' => function($path) {
// if: $path is directory: figure out when files were changed in directory
// else: use original hash function in \yii\web\AssetManager
}
],
]
For a sample implementation for finding the max modified date over all asset files in a bundle you could look at this comment by wookie @ http://php.net/manual/en/function.filemtime.php#35779
有关查找包中所有资产文件的最大修改日期的示例实现，您可以查看 wookie @ http://php.net/manual/en/function.filemtime.php#35779 的此评论
Note that modification to any asset file will create a new directory in web/assets, and regular cleanup will remain necessary. However, browser cache aside, refreshing the page will follow the latest changes.
请注意，对任何资产文件的修改都会在 中创建一个新目录web/assets，并且仍然需要定期清理。但是，除了浏览器缓存之外，刷新页面将遵循最新的变化。
