The same example, in each framework

The showcase example for Dialog, as written in each framework. Lines that only React has are marked.

Measured, per framework

Dialog in each framework, side by side. Lower is better for size, time and memory. No outside baseline: the frameworks are compared with each other only.

Measured
Nov 5 on Apple M3 Max, Chromium 156, 35 runs per framework over 5 page loads. The range under each time is the spread of the per-load medians.
Tests
Dialog's tests in each framework's suites, jsdom and Chromium together, from the latest run. React runs the React tests on the port; the other four also run the shared behaviour tests.

Same props, five spellings

The Dialog.Root props as each framework writes them. A name that differs from React is marked.

React
Props and callbacks have upstream's names and signatures: onCheckedChange(checked, details), onOpenChange(open, details), onValueChange(value, details).
Vue
Props keep upstream's names and can be written in kebab case in a template (:default-checked, :side-offset). Upstream's callbacks are Vue events with the same arguments: checkedChange(checked, details), openChange(open, details), valueChange(value, details).
Svelte
Callbacks are props with upstream's names and arguments: onCheckedChange(checked, details), onOpenChange(open, details), onValueChange(value, details), with details.cancel(), reason and event. Native event props use Svelte's names (onclick, onkeydown).
Angular
Inputs are signal inputs with upstream's names (checked, disabled, nativeButton); boolean inputs also work as bare attributes. Each callback with details is an output named without on: checkedChange, openChange, valueChange.
Solid
Callbacks keep upstream's names and arguments: onCheckedChange(checked, details), with details.cancel() and details.event. Native handlers are camelCase (onClick, onKeyDown), as Solid 2 requires.
