Holler.js

real-time, in-app notifications for web and mobile via the command line

1. Install a module

Holler is built with Node, uses Faye for communication, and uses Alertify for notifications. If you don't have Node yet, install the hell out of it. After doing so, the npm command should be available via the command line. Then we just install Faye:

npm install faye

2. Add a script tag

On the client, Holler can be easily configured to use a specific host and port regardless of the app's http server. This is done via a global hollerConfig object. The holler-client.js script tag should then be included:

<script>
  var hollerConfig = {
    host: "http://127.0.0.1",
    port: "1337"
  }
</script>
<script type="text/javascript" src="PATH/TO/holler-client.min.js"></script>

Heads up! The hollerConfig object is optional. If it is not defined, the host will default to 127.0.0.1 and the port will default to 1337.

3. Start a server

The server can be started with an optional port. If no port is specified, it will be defaulted to 1337.

cd path/to/holler/src 
node holler-server.js 1337

4. Holler stuff

Show notifications to all users currently using your app in real-time using holler.js. Notifications use Alertify so they look nice and sexy. See it in action.

Log Messages

node holler.js http://yourServerUrl:port log "This is a standard log message."

Success Messages

node holler.js http://yourServerUrl:port success "This is a success message."

Error Messages

node holler.js http://yourServerUrl:port error "This is an error message."

Try this! Open up multiple browser windows all pointing to your test page. All windows should receive the notification in real-time.
