yii2-version-assetmgr
A drop in replacement AssetManager for the Yii2 framework. Yii's default
AssetManager hashes assets based on path + Yii version + file modification time,
but if your website is being served behind a load balancer from multiple web
servers and the file mtimes are different, this could lead to serving assets
from different paths., (*1)
To combat this, instead the VersionAssetManager hashes path + Yii version +
application version. Application version is read from the version key of the
params array from the configuration file:, (*2)
'params' => [
'version' => '1.0.0'
],
Installation
The preferred way to install this extension is through composer., (*3)
Either run, (*4)
php composer.phar require --prefer-dist jhancock/yii2-version-assetmgr "*"
or add, (*5)
"jhancock/yii2-version-assetmgr": "*"
to the require section of your composer.json file., (*6)
Configuration
Configure your application to use the VersionAssetManager by adding the
following component configuration:, (*7)
'assetManager' => [
'class' => 'jhancock\VersionAssetMgr\VersionAssetManager',
],
You should then set a version parameter in the params array when you publish
your application., (*8)
In the development environment, either omit setting the version key in the
config, set it to Development, or omit it altogether and it will default to
Development. When the version is Development, we instead hash path + Yii
version + time() to guarantee that we always bust cache in the development
environment. This means that every pageload will create new folders under your
assets directory and copy lots of files. It is therefore recommended that you
turn on symlinking by setting linkAssets to true under the assetManager
component configuration like so:, (*9)
'assetManager' => [
'class' => 'jhancock\VersionAssetMgr\VersionAssetManager',
'linkAssets' => true,
],
