Debug toolbar and debugger

Yii2 includes a handy toolbar to aid faster development and debugging as well as debugger. Toolbar displays information about currently opened page while using debugger you can analyze data collected before.

Installing and configuring

Add these lines to your config file:

'preload' => ['debug'],
'modules' => [
	'debug' => ['yii\debug\Module']
]

Note: by default the debug module only works when browsing the website from the localhost. If you want to use it on a remote (staging) server, add the parameter allowedIPs to the config to whitelist your IP, e.g. :**

'preload' => ['debug'],
'modules' => [
	'debug' => [
		'class' => 'yii\debug\Module',
		'allowedIPs' => ['1.2.3.4', '127.0.0.1', '::1']
	]
]

If you are using enableStrictParsing URL manager option, add the following to your rules:

'urlManager' => [
	'enableStrictParsing' => true,
	'rules' => [
		// ...
		'debug/<controller>/<action>' => 'debug/<controller>/<action>',
	],
],
