NumberField

NumberField renders a Cratis-owned native numeric input with optional constraints.

Usage

The excerpt assumes MyCommand is a generated command proxy with the bound properties, and visible / setVisible is component state.

import { CommandDialog } from '@cratis/components/CommandDialog';
import { NumberField } from '@cratis/components/CommandForm';

<CommandDialog<MyCommand>
    command={MyCommand}
    title='Edit order'
    visible={visible}
    onSuccess={() => setVisible(false)}
    onCancel={() => setVisible(false)}
>
    <NumberField<MyCommand> value={c => c.quantity} title="Quantity" min={1} max={100} />
    <NumberField<MyCommand> value={c => c.price} title="Price" min={0} step={0.01} placeholder="0.00" />
</CommandDialog>

Props

Prop	Type	Default	Description
value	(instance: TCommand) => unknown	—	Required. Accessor function that returns the bound property from the command instance. Pass the command type as the generic parameter for full type safety.
placeholder	string	—	Placeholder text shown when the field is empty.
min	number	—	Minimum allowed value.
max	number	—	Maximum allowed value.
step	number	—	Increment/decrement step size.

Every field also accepts Arc’s shared field props, such as title, description, initialValue, and noInitialValue, and the accessibility props id, aria-label, and aria-describedby. See Accessible names and validation errors.

Behavior

• Shows 0 while the bound property is unset. See Field defaults and command values.
• The field spans full width within its container.
• Validation state is reflected through aria-invalid and data-invalid.
• When the value is cleared, it falls back to 0.
