Text input

TextInput is used for entering any single-line input with an optional autocomplete.

Theme | Example code

Usage

TextInput is an uncontrolled component. You can listen to value changes via onChange prop.

import React, {useState} from 'react';
import {render, Box, Text} from 'ink';
import {TextInput} from '@inkjs/ui';

function Example() {
	const [value, setValue] = useState('');

	return (
		<Box flexDirection="column" gap={1}>
			<TextInput placeholder="Start typing..." onChange={setValue} />
			<Text>Input value: "{value}"</Text>
		</Box>
	);
}

render(<Example />);

Default value

Default value can be set via defaultValue prop.

import React, {useState} from 'react';
import {render, Box, Text} from 'ink';
import {TextInput} from '@inkjs/ui';

function Example() {
	const [value, setValue] = useState('Jane');

	return (
		<Box flexDirection="column" gap={1}>
			<TextInput
				placeholder="Start typing..."
				defaultValue={value}
				onChange={setValue}
			/>

			<Text>Input value: "{value}"</Text>
		</Box>
	);
}

render(<Example />);

Autocomplete

TextInput can suggest values to autocomplete input with via suggestions prop, which contains an array of strings. As user is typing, TextInput finds the first item in suggestions array that begins with an input string that user has already entered. Matching of items in suggestions is case-sensitive.

When user presses enter, current suggestion will replace the input value.

import React, {useState} from 'react';
import {render, Box, Text} from 'ink';
import {TextInput} from '@inkjs/ui';

function Example() {
	const [value, setValue] = useState('');

	return (
		<Box flexDirection="column" gap={1}>
			<TextInput
				placeholder="Start typing..."
				suggestions={['Abby', 'Angel', 'Annie']}
				onChange={setValue}
			/>

			<Text>Input value: "{value}"</Text>
		</Box>
	);
}

render(<Example />);

Submit on enter

When you're only looking for the final value when user presses enter, you can use onSubmit instead of onChange prop.

import React, {useState} from 'react';
import {render, Box, Text} from 'ink';
import {TextInput} from '@inkjs/ui';

function Example() {
	const [value, setValue] = useState('');

	return (
		<Box flexDirection="column" gap={1}>
			<TextInput placeholder="Start typing..." onSubmit={setValue} />
			<Text>Input value: "{value}"</Text>
		</Box>
	);
}

render(<Example />);

Disabled

When there are two or more text inputs, only one should be receiving user input at a time, while others should be disabled via isDisabled prop.

import React, {useState} from 'react';
import {render, Box, Text} from 'ink';
import {TextInput} from '@inkjs/ui';

function Example() {
	const [activeInput, setActiveInput] = useState('name');
	const [name, setName] = useState('');
	const [surname, setSurname] = useState('');

	return (
		<Box flexDirection="column" gap={1}>
			<Box flexDirection="column">
				<TextInput
					isDisabled={activeInput !== 'name'}
					placeholder="Enter your name..."
					onChange={setName}
					onSubmit={() => {
						setActiveInput('surname');
					}}
				/>

				<TextInput
					isDisabled={activeInput !== 'surname'}
					placeholder="Enter your surname..."
					onChange={setSurname}
					onSubmit={() => {
						setActiveInput('none');
					}}
				/>
			</Box>

			<Box flexDirection="column">
				<Text>Name: "{name}"</Text>
				<Text>Surname: "{surname}"</Text>
			</Box>
		</Box>
	);
}

render(<Example />);
