Usage
usage.tsx
import { MaskInput } from "@/components/ui/mask-input";<MaskInput mask="phone" value={phone} onValueChange={(_maskedValue, unmaskedValue) => setPhone(unmaskedValue)} placeholder="Enter phone number" invalid={hasPhoneError}/>- Collect structured personal information while guiding users with input masks.
- Use for phone numbers, Social Security numbers, dates, or similar fixed-format values.
- Pair masked inputs with React Hook Form and Zod validation in a settings, onboarding, or profile form.
Examples
Phone number field
Stores the unmasked phone value while the component displays the formatted value.
phone-number-field.tsx
import * as React from "react";import { MaskInput } from "@/components/ui/mask-input";export function PhoneField() { const [phone, setPhone] = React.useState(""); return ( <MaskInput mask="phone" value={phone} onValueChange={(_maskedValue, unmaskedValue) => setPhone(unmaskedValue)} placeholder="Enter phone number" /> );}SSN field with validation state
Uses the SSN mask and marks the input invalid when validation fails.
ssn-field-with-validation-state.tsx
import * as React from "react";import { MaskInput } from "@/components/ui/mask-input";export function SsnField() { const [ssn, setSsn] = React.useState(""); const invalid = ssn.length > 0 && ssn.length < 9; return ( <MaskInput mask="ssn" value={ssn} onValueChange={(_maskedValue, unmaskedValue) => setSsn(unmaskedValue)} placeholder="Enter SSN" invalid={invalid} /> );}Birth-date field
Uses the date mask for a consistently formatted birth-date input.
birth-date-field.tsx
import * as React from "react";import { MaskInput } from "@/components/ui/mask-input";export function BirthDateField() { const [birthDate, setBirthDate] = React.useState(""); return ( <MaskInput mask="date" value={birthDate} onValueChange={(_maskedValue, unmaskedValue) => setBirthDate(unmaskedValue)} placeholder="Enter birth date" /> );}API reference
PropTypeDefaultDescription
mask"phone" | "ssn" | "date"—Selects the built-in input mask used by the demo.
valuestring—Controlled value passed to the masked input.
onValueChange(maskedValue: string, unmaskedValue: string) => void—Called when the value changes, providing both the displayed masked value and the unmasked value.
placeholderstring—Placeholder text shown when the field is empty.
invalidboolean—Marks the input as invalid for the form's validation state.
Accessibility
- Every field is rendered with a visible FormLabel, and FormControl connects the label to its input through the shadcn form primitives.
- FormMessage provides field-level validation feedback from the Zod schema.
- The invalid state is derived from each field's React Hook Form error and is passed to MaskInput.
- The form uses a submit button with type="submit" and a separate reset button with type="button", preventing accidental submission when resetting.
- The example includes descriptive helper text for each field; ensure the underlying MaskInput preserves keyboard input and exposes its invalid state to assistive technology.
