Widget JS generator.

Produces a self-contained, framework-agnostic JavaScript bundle served at

GET /widget.js. Embed on any page with:
|
||||
|
||||
<script
|

src="https://api.yoursite.com/widget.js"
|

data-chatbot="<chatbot-id>">

|

Works on vanilla HTML, WordPress, Webflow, Shopify, Next.js (_document),
|
||||
and any framework where you control the HTML shell.
|
||||
|
||||
For React/Vue projects that want a native component, host-side devs can call
|
||||
window.Contexta.open() / .close() / .toggle()
|
||||
from their own button, or await the dedicated npm package (@contexta/widget).
|
||||
|
||||
Design decisions
|
||||
----------------
|
||||
- All CSS is ID-scoped (#ctxa-*) to avoid colliding with host-page styles.
|
||||
- The iframe src is set lazily on first open — zero network cost until use.
|
||||
- document.currentScript is captured synchronously (before any async code)
|
||||
so it works even when the host page has many script tags.
|
||||
- z-index 2147483647 is the highest a browser will honour.
|
||||
- sandbox attribute restricts the iframe while still allowing forms/popups.
