TextInput

A text input backed by native SwiftUI and Jetpack Compose components, with a React Native-compatible API.

Android

iOS

Web

Included in Expo Go

Recommended version:

~56.0.26

A text input that routes to TextField from @expo/ui/jetpack-compose on Android, TextField from @expo/ui/swift-ui on iOS, and React Native's TextInput on web.

The API mirrors React Native's TextInput, with two changes: value and selection are observable state objects (created with useNativeState), and onChangeText can be a worklet for synchronously updating the state on the UI thread.

Installation

Terminal

- npx expo install @expo/ui

- yarn expo install @expo/ui

- pnpm expo install @expo/ui

- bun expo install @expo/ui

If you are installing this in an existing React Native app, make sure to install expo in your project.

Usage

Uncontrolled

Omit value and the field manages its own text internally. Use onChangeText to observe edits, and use the ref for imperative actions like focus, blur, and clear.

UncontrolledTextInputExample.tsx

import { Button, Column, Host, TextInput, type TextInputRef } from '@expo/ui';
import { useRef } from 'react';

export default function UncontrolledTextInputExample() {
  const inputRef = useRef<TextInputRef>(null);

  return (
    <Host matchContents={{ vertical: true }}>
      <Column spacing={8}>
        <TextInput
          ref={inputRef}
          defaultValue="hello"
          placeholder="Type here"
          onChangeText={value => console.log(value)}
        />
        <Button label="Clear" onPress={() => inputRef.current?.clear()} />
      </Column>
    </Host>
  );
}

Controlled

Pass value to drive the field from a useNativeState observable. The example below replaces Hello with World as you type.

ControlledTextInputExample.tsx

import { Host, TextInput, useNativeState } from '@expo/ui';
import { useCallback } from 'react';

export default function ControlledTextInputExample() {
  const text = useNativeState('');

  const handleChangeText = useCallback(
    (value: string) => {
      'worklet';
      text.value = value === 'Hello' ? 'World' : value;
    },
    [text]
  );

  return (
    <Host matchContents={{ vertical: true }}>
      <TextInput value={text} placeholder="Type here" onChangeText={handleChangeText} />
    </Host>
  );
}

Worklet masking

Add the 'worklet' directive to onChangeText for synchronously updating the state on the UI thread. Writes to value land without the JS-thread round-trip that can cause cursor flicker.

Note: Worklets require installing react-native-worklets.

PhoneMaskExample.tsx

import { Host, TextInput, useNativeState } from '@expo/ui';
import { useCallback } from 'react';

function formatPhone(input: string) {
  'worklet';
  const digits = input.replace(/\D/g, '').slice(0, 10);
  if (digits.length <= 3) return digits;
  if (digits.length <= 6) return `(${digits.slice(0, 3)}) ${digits.slice(3)}`;
  return `(${digits.slice(0, 3)}) ${digits.slice(3, 6)}-${digits.slice(6)}`;
}

export default function PhoneMaskExample() {
  const phone = useNativeState('');
  const selection = useNativeState({ start: 0, end: 0 });

  const handleChangeText = useCallback(
    (value: string) => {
      'worklet';
      const formatted = formatPhone(value);
      if (formatted !== value) {
        phone.value = formatted;
        // Snaps to end for demo. Real masks need smarter cursor handling.
        selection.value = { start: formatted.length, end: formatted.length };
      }
    },
    [phone, selection]
  );

  return (
    <Host matchContents={{ vertical: true }}>
      <TextInput
        value={phone}
        selection={selection}
        keyboardType="phone-pad"
        placeholder="(555) 123-4567"
        onChangeText={handleChangeText}
      />
    </Host>
  );
}

Unsupported React Native props

Some React Native TextInput props are not supported, because Compose's TextField or SwiftUI's TextField does not expose an equivalent, or because the prop is replaced by a different mechanism. See the API section below for the supported props. If a missing prop blocks your use case, open an issue so it can be prioritized.

import { TextInput, useNativeState } from '@expo/ui';
