Number field
A numeric input with increment and decrement buttons, and a scrub area
import { NumberField } from "@nyte-ai/ui/number-field";A numeric input that steps with buttons, arrow keys, the mouse wheel, and a drag area. No Nyte styling here.
Usage
- Give the field an accessible name. Point a
<label htmlFor>at theidyou set onNumberField.Input. A placeholder is not a name. formattakesIntl.NumberFormatOptions, so a currency or a percent field is a format option, not a suffix you render.stepsets the base increment. Alt steps bysmallStep, Shift bylargeStep.ScrubAreaandScrubAreaCursorare optional. Skip both when the field only needs typing and the two buttons.

Root
Groups all parts of the number field and manages its state.
Renders a <div> element.
Root Props:
| Prop | Type | Default | Description |
|---|---|---|---|
| name | string | - | Identifies the field when a form is submitted. |
| defaultValue | number | - | The uncontrolled value of the field when it's initially rendered. To render a controlled number field, use the value prop instead. |
| value | number | null | - | The raw numeric value of the field. |
| onValueChange | ((value: number | null, eventDetails: NumberField.Root.ChangeEventDetails) => void) | - | Callback fired when the number value changes. The eventDetails.reason indicates what triggered the change: 'input-change' for parseable typing or programmatic text updates'input-clear' when the field becomes empty'input-blur' when formatting (and clamping, if enabled) occurs on blur'input-paste' for paste interactions'keyboard' for arrow-key/Home/End stepping (typing digits uses 'input-change'/'input-clear')'increment-press' / 'decrement-press' for button presses on the increment and decrement controls'wheel' for wheel-based scrubbing'scrub' for scrub area drags |
| onValueCommitted | ((value: number | null, eventDetails: NumberField.Root.CommitEventDetails) => void) | - | Callback function that is fired when the value is committed.
It runs later than onValueChange, when: The input is blurred after typing a value.The pointer is released after scrubbing or pressing the increment/decrement buttons. It runs simultaneously with onValueChange when interacting with the keyboard or the
mouse wheel. Warning: This is a generic event not a change event. |
| allowOutOfRange | boolean | false | When true, direct text entry may be outside the min/max range without clamping,
so native range underflow/overflow validation can occur.
Step-based interactions (keyboard arrows, buttons, wheel, scrub) still clamp. |
| form | string | - | Identifies the form that owns the hidden input. Useful when the number field is rendered outside the form. |
| locale | Intl.LocalesArgument | - | The locale of the input element. Defaults to the user's runtime locale. |
| snapOnStep | boolean | false | Whether the value should snap to the nearest step when incrementing or decrementing. |
| step | number | 'any' | 1 | Amount to increment and decrement with the buttons and arrow keys, or to scrub with pointer movement in the scrub area.
To always enable step validation on form submission, specify the min prop explicitly in conjunction with this prop.
Specify step="any" to always disable step validation; interactive stepping then uses a base amount of 1, while the alt and shift keys still step by smallStep and largeStep. |
| smallStep | number | 0.1 | The small step value of the input element when incrementing while the alt key is held.
Snaps to multiples of this value when snapOnStep is enabled. |
| largeStep | number | 10 | The large step value of the input element when incrementing while the shift key is held.
Snaps to multiples of this value when snapOnStep is enabled. |
| min | number | - | The minimum value of the input element. |
| max | number | - | The maximum value of the input element. |
| allowWheelScrub | boolean | false | Whether to allow the user to scrub the input value with the mouse wheel while focused and hovering over the input. |
| format | Intl.NumberFormatOptions | - | Options to format the input value. |
| disabled | boolean | false | Whether the component should ignore user interaction. |
| readOnly | boolean | false | Whether the user should be unable to change the field value. |
| required | boolean | false | Whether the user must enter a value before submitting a form. |
| inputRef | React.Ref<HTMLInputElement> | - | A ref to access the hidden input element. |
| id | string | - | The id of the input element. |
| className | string | ((state: NumberField.Root.State) => string | undefined) | - | CSS class applied to the element, or a function that returns a class based on the component's state. |
| style | React.CSSProperties | ((state: NumberField.Root.State) => React.CSSProperties | undefined) | - | Style applied to the element, or a function that returns a style object based on the component's state. |
| render | ReactElement | ((props: HTMLProps, state: NumberField.Root.State) => ReactElement) | - | Allows you to replace the component's HTML element
with a different tag, or compose it with another component. Accepts a ReactElement or a function that returns the element to render. |

Accessibility
- Arrow Up and Arrow Down step the value. Home and End jump to
minandmax, when those bounds are set. - Alt with an arrow key steps by
smallStep, Shift bylargeStep. - The input carries
aria-roledescription="Number field"by default. That is a role description, not a name, so still label the control. - Wheel scrubbing is off unless you set
allowWheelScrub, and it only applies while the input is focused and hovered.
