Extension Points Demonstrated

#	Extension	Where	Side
1	@aiui.page()	app.py	Server
2	aiui.form_action()	app.py	Server (returns dict)
3	@aiui.register_page_action()	app.py	Server (form handler)
4	window.aiui.registerView()	plugin.js	Client

Endpoints Exercised

Method	Endpoint	Purpose
GET	/api/health	Server health check
GET	/api/pages	List all registered pages
GET	/api/pages/{id}/data	Get a page's rendered components
POST	/api/pages/{id}/action	Submit a form-action from aiui.form_action()
GET	/api/features	List all registered feature protocols
GET	/api/theme	Get current theme variables
GET	/api/overview	Dashboard statistics

Run

python app.py
# Then visit: http://localhost:8082

Testing the custom component + custom view

The timeline component and the custom-view page are client-side extensions. app.py loads plugin.js automatically via aiui.set_custom_js() — no DevTools paste required.

1. Open http://localhost:8082 in the browser
2. Navigate to Custom Component → the timeline renders as a styled list
3. Navigate to Client-Only View → a JS-rendered clock appears

Note: aiui.set_custom_js(path) injects client-side JS from a file path at page load. See docs/features/how-to-add-a-feature.md for the extension API contract.

Testing the form action

1. Navigate to Contact Form
2. Fill in the form (Name / Email / Age / Role / Newsletter / Notes)
3. Click Save Contact
4. The form POSTs to /api/pages/contact-form/action
5. The server-side @aiui.register_page_action("contact-form") handler appends the contact to an in-memory list and returns {"status": "saved", ...}
6. Reload the page — the contact appears in the table below the form
