Bundle to add a screen frontend to the administration.

Description

This bundle adds screen as a bundle to the administration. Furthermore, it adds a new pull strategy to the frontend, where a middleware is not needed. If this strategy is chosen the options to reload the screen from the adminstration are lost.

By moving the screen into the adminstration the possibility of a preview of screens and channels in the administration has been added.

There is also a possibility of making public channels/screens that have a public url. This url can be opened by multiple browsers and uses the pull strategi.

Configuration

Add the following to routing.yml:

os2display_screen:
    resource: "@Os2DisplayScreenBundle/Resources/config/routing.yml"
    prefix:   /

Add the following to security.yml firewalls section:

screen_bundle_public:
    pattern: ^/screen/public/(.*)
    security: false

nginx setup

The following should be added to the admin nginx conf.

    location /middleware/ {
        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_buffering off;

        proxy_pass http://nodejs_middleware/;
        proxy_redirect off;
    }

Alternatively this location name can be

Access screen with middleware

To open screen go to /screen/.

Access screen without middleware

Go to the administration under a screen. Make it publicly available. Distribute the url.
