README

A redis driven like engine.

Installation

Install through composer:

php -d memory_limit=-1 composer.phar require xlabs/notificationsbundle

In your AppKernel

public function registerbundles()
{
    return [
    	...
    	...
    	new XLabs\NotificationsBundle\XLabsNotificationsBundle(),
    ];
}

Routing

Append to main routing file:

# app/config/routing.yml

x_labs_notifications:
    resource: "@XLabsNotificationsBundle/Resources/config/routing.yml"
    prefix:   /

Configuration sample

Default values are shown below:

# app/config/config.yml
  
x_labs_notifications:
    nodejs_settings:
        host: your.host.com
        port: 3026
        schema: https
        ssl_key: /etc/nginx/.../your.host.com.key
        ssl_cert: /etc/nginx/.../your.host.com.crt
        ssl_bundle: /etc/nginx/.../your.host.com.(bundle | crt)
    redis_settings:
        host: 192.168.5.23
        port: 6379
        database_id: 20
        _key_namespace: 'your:namespace:notifications'
    settings:
        message_ttl: <expiration_period_in_hours> | false
        socket_io_client_reconnect_atempts: <number_attempts> | false(default - for unlimited attempts)

Make sure you update all assets:

php bin/console assets:install --symlink

Run command to create NodeJS server file:

php bin/console xlabs_notifications:create:server

IMPORTANT: Make sure to run this command once you have the config set in the project. If the config changes, you will have to regenerate the server again.

Install NodeJS dependencies under "web/notifications/":

nvm install 0.10.45
nvm use 0.10.45
npm install

Usage

Append this before the end of body tag in your template:

{{ render(controller('XLabsNotificationsBundle:Notifications:loader')) }}

Launch the NodeJS server:

node web/notifications/server.js

Render user notifications

Append this anywhere in your template:

{% include 'XLabsNotificationsBundle:Frontend:notifications.html.twig' with {
    'max_results': <num_results>
} %}

Ajax driven pagination will be automatically added.

If you want to render notifications your own way, override the template by creating:

app/Resources/XLabsNotificationsBundle/views/Frontend/notification.html.twig

To override the "no results" template:

app/Resources/XLabsNotificationsBundle/views/Frontend/no_results.html.twig

To remove (ajax) a notification, add to your DOM element the following attribute:

'data-xlabs-notifications-remove="<notification_id>"'

To remove (ajax) all notifications, add to your DOM element the following attribute:

'data-xlabs-notifications-remove="all"'

To mark as read (ajax) a notification, add to your DOM element the following attribute:

'data-xlabs-notifications-markAsRead="<notification_id>"'

You can also define a custom JS callback function for all these operations above by adding the following attribute, so it would be executed after the action:

'data-xlabs-callback="YOUR_JS_FUNCTION"'

Notifications cleanup

It´s strongly recommended that you create a daily cronjob to remove from user notifications all the items that have automatically expired. To do so:

$xlabs_storage = $container->get('xlabs_notifications_storage');
foreach($users as $user)
{
    $xlabs_storage->clearExpiredUserNotifications($user->getId())
}

Requirements

The node js connection is made through a nginx reverse proxy. Make sure to set a nginx vhost:

server {
    listen 443 ssl;

    server_name <x_labs_chat.nodejs_settings.host>;

    ## SSL settings
    ssl on;
    ssl_certificate <x_labs_chat.nodejs_settings.ssl_cert>;
    ssl_certificate_key <x_labs_chat.nodejs_settings.ssl_key>;

    ## SSL caching/optimization
    ssl_protocols        SSLv3 TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers RC4:HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers on;
    keepalive_timeout    60;
    ssl_session_cache    shared:SSL:10m;
    ssl_session_timeout  10m;

	location / {
        #proxy_set_header 'Access-Control-Allow-Origin' '*';

        #proxy_set_header X-Real-IP $remote_addr;
        #proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        #proxy_set_header Host $http_host;
        #proxy_set_header X-NginX-Proxy true;
        #proxy_redirect off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;

        proxy_pass https://<your_internal_nodejs_server_ip>:<x_labs_chat.nodejs_settings.port>;
    }
}
