`GeolocationButton`¶

Spoofable geolocation form fields with progressive enhancement.


Import	`from hedron import GeolocationButton`
Distribution	`hedron`
Backend activity	No
Normal render mode	`RenderMode.FRAGMENT`

Live demo¶

Spoofable form fields — not authorization.

The preview is a local docs simulation (not a running Hedron server). Interactive demos show a “Simulated HTMX” trace when applicable.

Basic use¶

from hedron import GeolocationButton

component = GeolocationButton()

Compose under Page for full documents, or return from a fragment route for HTMX swaps.

How it works¶

Phase 0.15 surface. Prefer native HTML semantics and ordinary HTTP actions.

This component's core behavior is server-rendered HTML and does not require a browser runtime. The preview is ordinary semantic HTML, so keyboard, form, link, and disclosure behavior comes from the platform.

Constructor and parameters¶

GeolocationButton(*, label: 'str' = 'Share location', lat_name: 'str' = 'lat', lon_name: 'str' = 'lon', accuracy_name: 'str' = 'accuracy', class_: 'str | None' = None, mark: 'str | None' = None, **kwargs: 'object') -> 'None'

Parameter	Type	Meaning
`label`	`str`	Accessible label text shown to users. Default: `'Share location'`.
`lat_name`	`str`	Form field name for latitude. Default: `'lat'`.
`lon_name`	`str`	Form field name for longitude. Default: `'lon'`.
`accuracy_name`	`str`	Form field name for reported accuracy. Default: `'accuracy'`.
`class_`	`str \| None`	Optional CSS class string (`class` in HTML). Default: `None`.
`mark`	`str \| None`	Optional stable test mark (`data-hedron-mark`). Default: `None`.

Composition and backend behavior¶

Keep GeolocationButton at the smallest semantic boundary. Fragment routes should return only the replaced region and preserve stable target IDs across success, validation, empty, loading, and error responses.

This component is primarily presentational; keep any mutation on an explicit action or component route.

Accessibility¶

Keyboard and screen-reader operable; no-JS fallback required where interactive.

Security¶

Escaping and SafeUrl / TrustedHtml are framework concerns; authorization and data exposure remain application code. Redact secrets before rendering.

Common mistakes¶

Do not treat client-only hints (geolocation, browser storage) as authorization.
Do not copy docs-preview JavaScript into an application server.

Testing¶

from hedron import RenderMode, render

result = render(component, mode=RenderMode.FRAGMENT)
assert result.html
assert not result.diagnostics
