属性详情

$commands 公共 属性

The commands that are used to perform the asset conversion. The keys are the asset file extension names, and the values are the corresponding target script types (either "css" or "js") and the commands used for the conversion.

You may also use a path alias to specify the location of the command:

[
    'styl' => ['css', '@app/node_modules/bin/stylus < {from} > {to}'],
]
public array $commands = ['less' => ['css''lessc {from} {to} --no-color --source-map'], 'scss' => ['css''sass {from} {to} --sourcemap'], 'sass' => ['css''sass {from} {to} --sourcemap'], 'styl' => ['css''stylus < {from} > {to}'], 'coffee' => ['js''coffee -p {from} > {to}'], 'ts' => ['js''tsc --out {to} {from}']]
$forceConvert 公共 属性

Whether the source asset file should be converted even if its result already exists. You may want to set this to be true during the development stage to make sure the converted assets are always up-to-date. Do not set this to true on production servers as it will significantly degrade the performance.

public boolean $forceConvert false
