Node.js server integration module (web-sockets)

Install with composer

composer require digitv/yii2sockets:1.*

Add console command controller to the config (controllerMap section):

'controllerMap' => [
    'node-sockets' => '\digitv\yii2sockets\commands\YiiNodeSocketsController',

Add session component to the 'components' section of main config:

'components' => [
        'session' => [
            'class' => 'digitv\yii2sockets\YiiNodeSocketSession',
            'keyPrefix' => 'sess_preffix_',
            'timeout' => 600,

It uses Redis DB connection to share session data with Node.js server. Of course you must use redis component to connect Redis DB. Add it in both configs (web and main).

'components' => [
        'redis' => [
            'class' => 'yii\redis\Connection',
            'hostname' => 'localhost',
            'port' => 6379,
            'database' => 0,

And add component do those configs (https not implemented yet):

'components' => [
        'nodeSockets' => [
            'class' => 'digitv\yii2sockets\YiiNodeSocket',
            'nodeJsHost' => 'localhost',
            'nodeJsPort' => 3001,
            'nodeJsScheme' => 'http',
            'nodeJsHostClient' => 'your-site.com',
            'serviceKey' => 'serviceKeyUsedForCommunication',
            'sessionKeyPrefix' => 'sess_preffix_',
            'channelsByPermissions' => [
                'channel_name' => 'permission',
                'channel_name_2' => [
                    'permission' => '@',
                    'url' => '/chat/index',     //URL on which users can connect to channel

Parameter channelsByPermissions is an array with channel names and permissions. If Yii::$app->user->can('permission') returns TRUE than channel channel_name will be added to user automatically. It runs on component init.

When configs are ready use console command to build Node.js config files:

./yii node-sockets/init

Node.js server

Server is in server subdirectory. Before first run you must install all Node.js modules. Go to server directory and install they with command

npm install

Now you can run server

node app.js

You can use environment variables to overwrite config options. For example:

NODE_ENV=production node app.js

In that case it runs in production mode with disabled debug information.


There are 3 message classes (I call it Frames):

  1. Basic (YiiNodeSocketFrameBasic) used for basic messages.

  2. jQuery (YiiNodeSocketFrameJQuery) used for jQuery DOM manipulations.

  3. Notify (YiiNodeSocketFrameGrowl) uses kartik-v/yii2-widget-growl to show messages for user.

  4. Alert (YiiNodeSocketFrameAlert) plays audio alert to user.


Send message with array[] body to channel test_channel. On front end will be used Javascript callback jsCallbackName.

        'id' => $model->id,
        'message' => Yii::t('app', 'You have new incoming call'),

Send message to this socket (example is used on AJAX request).

    ->setText('Hello world')

Send jQuery frame to user with ID 1. It will remove element with selector #element_selector.


Send Alert frame to channel test_channel to all browser windows (not active too):


Please notice, that you need to render block with <audio> element in order to play it.

Also includes example YiiNodeSocketFrameChat frame type that sends message depending on its content:

  1. to recipient_id and author_id if object contains both those properties;
  2. to channel composed automatically otherwise. You can see frame source for details.
$message = new ChatMessage([
    'recipient_id' => 4,
    'author_id' => 1,
    'message' => 'test text message',


Javascript callback example:

YiiNodeSockets.callbacks.jsCallbackName = function (message, _socket) {
