The preferred way to install this extension is through composer.

composer require yiisoft/yii-debug --dev

The debug extension also can be installed without the --dev flag if you want to collect data in production. Specify needed collectors only to reduce functions overriding and improve performance.


Once the extension is installed, modify your config/common/params.php as follows:

return [
    'yiisoft/yii-debug' => [
        'enabled' => true,
    // ...

All included collectors start listen and collect payloads from each HTTP request or console run.

Install both yiisoft/yii-debug-api and yiisoft/yii-dev-panel to be able to interact with collected data through UI.
