yii2, npm, node, redis
The preferred way to install this extension is through composer.
Either run
php composer.phar require --prefer-dist dkhru/yii2-socket-events "*"
or add
"dkhru/yii2-socket-events": "*"
to the require section of your composer.json
file.
Once the extension is installed, cd vendor/dkhru/nodejs
and install node modules npm install console-stamp express redis socket.io
Generate SSL certificates for rtserver.
Copy config.js.example
to config.js
For testing simple run in console node rtserver.js
On linux server use init script example in rtserver.initd
In yii2 configure SocketEvent component
...
'components'=>[
...
'se'=>[
'class'=>\dkhru\socketEvents\SE::className(),
'socketUrl'=>https://127.0.0.1:8089,
],
...
]

Now, you can create you server driven widgets from RegisterSEWidget
Simple example:
...
class RestWidget extends RegisterSEWidget
{
public $rest;
public function init()
{
if( \Yii::$app->user->isGuest )
throw new ForbiddenHttpException();
$this->object='user';
$this->id=\Yii::$app->user->id;
$restJs=<<<JS
function(data){
if(data['rest']){
el = $('div.rest);
if(el.length)
el.html(data.rest);
}
}
JS;
$this->handlers=[
'rest'=>$restJs // добавляем обработчик
];
parent::init();
}
public function run()
{
parent::run();
return Html::tag('div',$this->rest.'₽',['class'=>'rest']);
}
}
After add widget to view you can update user rest in client browser from server.
SE::emit('user',$user_id,['handler'=>'rest','data'=>['rest'=>200.00]);
