ReactBoard

What is it ?

ReactBoard is an extensible dashboard based on React, Rachet and the Symfony Components. Install it on a server, set up the applications you wish and plug a screen !

You can interact in real time with it via an http API.

Getting started

Create a composer.json

{
    "autoload": {
        "psr-0": { "": "src/" }
    },
    "require": {
        "owlycode/reactboard": "~0.1"
    }
}

And then execute the following commands

composer install
cp vendor/owlycode/reactboard/app . -r
mv app/app.php.dist app/app.php

Now run the application with php app/app.php

When browsing http://localhost:8080/home/landing, you should see the welcome page.

Playing around

The following applications are included : hello, prompt, twitter and vlc.

hello is the one you are seeing by default, it's basically an hello world.
prompt will display a single message.
twitter will display a live updated list of tweets from a hashtag.
vlc will display a player (your browser needs the VLC plugin) streaming from a specified source.

You can switch between applications by issuing calls to the http://localhost:8080/home/command URL. Give a try to the following commands and see what happens in your browser :

curl "http://localhost:8080/home/command?app=prompt&message=Oh%20Hi!"

Before running this one, you will need to setup a twitter application and enter its credentials in app/app.php

curl "http://localhost:8080/home/command?app=twitter&hashtag=symfony"

Before running this one, make sure you have vlc installed (tested on linux & windows). Don't forget to killall vlc when you are done.

vlc screen:// --screen-fps=20 --live-caching=10 --sout="#transcode{vcodec=mp2v,vb=256,fps=20,scale=Auto,acodec=none}:http{mux=raw,dst=:8081/}" -I dummy &
curl "http://localhost:8080/home/command?app=vlc&streamer=127.0.0.1:8081"

Customize the theme

Create your own css file in app/Resources/css and replace the default theme in app/app.php :

$kernel->link(new ExternalAsset(__DIR__ . '/Resources', 'css/your-theme-file.css'));

Create your own application

Create an src/MyNamespace/MyAppName folder with the following files :

<?php
// src/MyNamespace/MyAppName/MyAppNameApplication.php

namespace MyNamespace\MyAppName;

use OwlyCode\ReactBoard\Application\AbstractApplication;
use OwlyCode\ReactBoard\Application\ApplicationInterface;

class MyAppNameApplication extends AbstractApplication implements ApplicationInterface
{
    /**
     * Called just before the socket server starts.
     */
    public function init()
    {
        $this->watch('my_app_name.request.index', function(){
            return $this->render('index.html.twig', array('status' => 'loaded'));
        });
    }

    public function getName()
    {
        return 'my_app_name';
    }
}

{# src/MyNamespace/MyAppName/views/index.html.twig #}

<h1>My application is {{ status }} ! :-)</h1>

Then register your newly created application in app/app.php:

$kernel->register(new MyAppNameApplication());

You can now start/restart ReactBoard, open your browser and try : curl "http://localhost:8080/home/command?app=my_app_name"

Going further :

ReactBoard is still in early development and more documentation will be coming. If you have any question please feel free to open an issue :-)

Meanwhile, to see how to do more advanced stuff, like loading your own assets or access the dependency injection mechanism, take a look at the builtin applications. The Twitter application is the most advanced and covers everything ReactBoard can do : application lifecycle events, live updates, dependency injection use, assets registering and many other things.
