Holler.js

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

1. Install a module

Holler is built with Node and is distributed as an npm module. If you don't have Node yet, install the hell out of it. Next we just install holler:

npm install holler

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.

holler-server 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

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

Success Messages

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

Error Messages

holler 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.
