Messenger - Alerts for the 21st Century
Messenger is a JavaScript library for displaying notification messages in web applications with support for updating messages in place, binding actions like retry or undo, and wrapping AJAX requests to show progress, success, and error states. It offers flexible theming through CSS classes, configurable message containers with positioning options, and integrations with jQuery AJAX and Backbone.js to automatically manage asynchronous operation feedback. Messages can include DOM event handlers, action buttons, and automatic retry logic for failed requests.
