real-time, in-app notifications and admin for web and mobile via the command line. see it in action
Sending notifications with Holler is as easy as four steps:
1. Install a module
npm install holler -g
2. Include Holler
New! Be sure to include the
holler.css stylesheet as of v1.9.0:
<link href="PATH/TO/holler/css" rel="stylesheet"/>
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:
3. Start a server
The server can be started with an optional port. If no port is specified, it will be defaulted to 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.
