q-chat Widget

The q-chat widget is a simple, customizable chat UI that you can easily integrate into any web project. It provides a chat button that users can click to open a chat window. The widget allows users to send messages, and it's designed to be integrated with a server or other backends to manage chat sessions.

Features

• Toggleable chat window
• Customizable look via CSS
• Easy-to-hook event system for custom backend integrations
• Lightweight, with no external dependencies
• SVG-based icons for scalability and customization
• Includes 'Send' button in addition to 'Enter' key for message sending

Installation

To install the q-chat widget, you can include the JavaScript and CSS files in your HTML:

<script src="/path/to/q-chat.js"></script>
<link rel="stylesheet" href="/path/to/q-chat.css" id="q-chat-css">

Make sure to replace /path/to/ with the actual path to the widget files.

Usage

Once you've included the widget files, the chat UI should be automatically activated on your webpage.

JavaScript Events

The q-chat widget emits the following custom events:

• qChatBefore: Fired before a message is sent. Can be canceled/edited.
• qChatAfter: Fired after a message is sent.

Example to hook into the qChatBefore event:

document.addEventListener('qChatBefore', function(event) {
  console.log("Before message send:", event.detail.content);
});

You can also send a message to the chat UI using the qChatReceive event like this:

document.dispatchEvent(new CustomEvent("qChatReceive", {
  detail: { content: "Hello from server" }
}));
