Prompts
The @clack/prompts package provides a collection of pre-built, high-level prompts that make it easy to create interactive command-line interfaces. It builds on top of the core package to provide a more developer-friendly experience.
Key Features
Section titled “Key Features”- Pre-built prompts: Ready-to-use prompt components
- Consistent styling: Unified look and feel across all prompts
- Type-safe: Full TypeScript support
- Customizable: Easy to extend and modify
- AbortController support: Cancel prompts programmatically
- Custom I/O streams: Use custom input/output streams
Installation
Section titled “Installation”npm install @clack/promptspnpm add @clack/promptsyarn add @clack/promptsThe prompts package is designed to be intuitive and easy to use. Each prompt function returns a Promise that resolves to the user’s input.
For more detailed examples and advanced usage patterns, check out our examples guide and best practices.
Common Options
Section titled “Common Options”All prompts share these common options:
Guide Lines
Section titled “Guide Lines”The withGuide option (boolean option, not a separate API) turns Clack’s border/guide lines on or off. Every prompt accepts it alongside message and friends. You can set it globally with updateSettings or override it per call.
import { const text: (opts: TextOptions) => Promise<string | symbol>
The text prompt accepts a single line of text.
text, function updateSettings(updates: ClackSettings): void
updateSettings } from '@clack/prompts';
// Disable globallyfunction updateSettings(updates: ClackSettings): void
updateSettings({ ClackSettings.withGuide?: boolean
withGuide: false });
// Or per-promptconst const name: string | symbol
name = await function text(opts: TextOptions): Promise<string | symbol>
The text prompt accepts a single line of text.
text({ TextOptions.message: string
The prompt message or question shown to the user above the input.
message: 'What is your name?', CommonOptions.withGuide?: boolean
withGuide: false, // Disable guide lines for this prompt});Session helpers use the same option on their second argument: intro(title, { withGuide: false }), outro(message, { withGuide: false }), and cancel(message, { withGuide: false }).
autocomplete and multiselect respect withGuide: false per prompt (as of v1.2.0), matching other prompts.
AbortController Support
Section titled “AbortController Support”All prompts accept a signal option for programmatic cancellation:
import { const confirm: (opts: ConfirmOptions) => Promise<boolean | symbol>
The confirm prompt accepts a yes or no choice, returning a boolean value
corresponding to the user's selection.
confirm } from '@clack/prompts';
// Auto-cancel after 10 secondsconst const shouldContinue: boolean | symbol
shouldContinue = await function confirm(opts: ConfirmOptions): Promise<boolean | symbol>
The confirm prompt accepts a yes or no choice, returning a boolean value
corresponding to the user's selection.
confirm({ ConfirmOptions.message: string
The message or question shown to the user above the input.
message: 'This will self-destruct in 10 seconds', CommonOptions.signal?: AbortSignal
signal: var AbortSignal: { new (): AbortSignal; prototype: AbortSignal; abort(reason?: any): AbortSignal; any(signals: AbortSignal[]): AbortSignal; timeout(milliseconds: number): AbortSignal;}
AbortSignal.function timeout(milliseconds: number): AbortSignal
timeout(10000),});Custom I/O Streams
Section titled “Custom I/O Streams”You can provide custom input and output streams for all prompts:
import { class Writable
Writable, class Readable
Readable } from 'node:stream';import { const text: (opts: TextOptions) => Promise<string | symbol>
The text prompt accepts a single line of text.
text } from '@clack/prompts';
declare const const customInput: Readable
customInput: class Readable
Readable;declare const const customOutput: Writable
customOutput: class Writable
Writable;
const const name: string | symbol
name = await function text(opts: TextOptions): Promise<string | symbol>
The text prompt accepts a single line of text.
text({ TextOptions.message: string
The prompt message or question shown to the user above the input.
message: 'What is your name?', CommonOptions.input?: Readable
input: const customInput: Readable
customInput, CommonOptions.output?: Writable
output: const customOutput: Writable
customOutput,});Available Prompts
Section titled “Available Prompts”Text Input
Section titled “Text Input”The text prompt accepts a single line of text.

message: 'What is your name?', TextOptions.placeholder?: string
A visual hint shown when the field has no content.
placeholder: 'John Doe', TextOptions.validate?: Validate<string>
A function or a Standard Schema
that validates user input. If a custom function is given, you should return a string or Error
to show as a validation error, or undefined to accept the result.
validate: (value: string | undefined

if (function isCancel(value: unknown): value is symbol
isCancel(const action: string | symbol
action)) { var process: NodeJS.Process
process.NodeJS.Process.exit(code?: number | string | null): never
The process.exit() method instructs Node.js to terminate the process
synchronously with an exit status of code. If code is omitted, exit uses
either the 'success' code 0 or the value of process.exitCode if it has been
set. Node.js will not terminate until all the 'exit' event listeners are
called.
To exit with a 'failure' code:
import { exit } from 'node:process';
exit(1);
The shell that executed Node.js should see the exit code as 1.
Calling process.exit() will force the process to exit as quickly as possible
even if there are still asynchronous operations pending that have not yet
completed fully, including I/O operations to process.stdout and process.stderr.
In most situations, it is not actually necessary to call process.exit() explicitly. The Node.js process will exit on its own if there is no additional
work pending in the event loop. The process.exitCode property can be set to
tell the process which exit code to use when the process exits gracefully.
For instance, the following example illustrates a misuse of the process.exit() method that could lead to data printed to stdout being
truncated and lost:
import { exit } from 'node:process';
// This is an example of what *not* to do:if (someConditionNotMet()) { printUsageToStdout(); exit(1);}
The reason this is problematic is because writes to process.stdout in Node.js
are sometimes asynchronous and may occur over multiple ticks of the Node.js
event loop. Calling process.exit(), however, forces the process to exit before those additional writes to stdout can be performed.
Rather than calling process.exit() directly, the code should set the process.exitCode and allow the process to exit naturally by avoiding
scheduling any additional work for the event loop:
import process from 'node:process';
// How to properly set the exit code while letting// the process exit gracefully.if (someConditionNotMet()) { printUsageToStdout(); process.exitCode = 1;}
If it is necessary to terminate the Node.js process due to an error condition,
throwing an uncaught error and allowing the process to terminate accordingly
is safer than calling process.exit().
In Worker threads, this function stops the current thread rather
than the current process.

Dynamic options (getter)
Section titled “Dynamic options (getter)”Instead of a static array, options can be a function whose this is the underlying AutocompletePrompt from @clack/core. The function runs again whenever the search text changes, so you can read this.userInput and return a new array in display order—for example closest / highest-score matches first (similar to fzf-style UIs). This pattern is what issue #467 discusses for custom ranking and libraries like Fuse.js.
The high-level autocomplete wrapper still applies its default filter (substring match on label, hint, and value) to whatever your getter returns. If you already narrow or rank items in the getter, disable that second pass with filter: (_search, _option) => true, or pass a custom (search, option) => boolean aligned with your getter.
options as a getter must be synchronous; there is no async API here—preload or sync work inside the function.
The same options shape is supported on autocompleteMultiselect.

Cancel
Section titled “Cancel”The cancel function defines an interruption of an interaction and therefore its end.
It accepts an optional string parameter which is displayed as a cancellation message.
import { const cancel: (message?: string, opts?: CommonOptions) => void
The cancel function defines an interruption of an interaction
and therefore its end.
cancel } from '@clack/prompts';import var process: NodeJS.Process
process from 'node:process';
function cancel(message?: string, opts?: CommonOptions): void
The cancel function defines an interruption of an interaction
and therefore its end.
cancel('Installation canceled');var process: NodeJS.Process
process.NodeJS.Process.exit(code?: number | string | null): never
The process.exit() method instructs Node.js to terminate the process
synchronously with an exit status of code. If code is omitted, exit uses
either the 'success' code 0 or the value of process.exitCode if it has been
set. Node.js will not terminate until all the 'exit' event listeners are
called.
To exit with a 'failure' code:
import { exit } from 'node:process';
exit(1);
The shell that executed Node.js should see the exit code as 1.
Calling process.exit() will force the process to exit as quickly as possible
even if there are still asynchronous operations pending that have not yet
completed fully, including I/O operations to process.stdout and process.stderr.
In most situations, it is not actually necessary to call process.exit() explicitly. The Node.js process will exit on its own if there is no additional
work pending in the event loop. The process.exitCode property can be set to
tell the process which exit code to use when the process exits gracefully.
For instance, the following example illustrates a misuse of the process.exit() method that could lead to data printed to stdout being
truncated and lost:
import { exit } from 'node:process';
// This is an example of what *not* to do:if (someConditionNotMet()) { printUsageToStdout(); exit(1);}
The reason this is problematic is because writes to process.stdout in Node.js
are sometimes asynchronous and may occur over multiple ticks of the Node.js
event loop. Calling process.exit(), however, forces the process to exit before those additional writes to stdout can be performed.
Rather than calling process.exit() directly, the code should set the process.exitCode and allow the process to exit naturally by avoiding
scheduling any additional work for the event loop:
import process from 'node:process';
// How to properly set the exit code while letting// the process exit gracefully.if (someConditionNotMet()) { printUsageToStdout(); process.exitCode = 1;}
If it is necessary to terminate the Node.js process due to an error condition,
throwing an uncaught error and allowing the process to terminate accordingly
is safer than calling process.exit().
In Worker threads, this function stops the current thread rather
than the current process.
exit(1);└ Installation canceled

Spinner Methods
Section titled “Spinner Methods”The spinner provides multiple methods to indicate different completion states:
import { const spinner: ({ indicator, onCancel, output, cancelMessage, errorMessage, frames, delay, signal, ...opts }?: SpinnerOptions) => SpinnerResult
spinner } from '@clack/prompts';
const const spin: SpinnerResult
spin = function spinner({ indicator, onCancel, output, cancelMessage, errorMessage, frames, delay, signal, ...opts }?: SpinnerOptions): SpinnerResult
spinner();const spin: SpinnerResult
spin.SpinnerResult.start(msg?: string): void
start('Processing');
// Success - shows green checkmarkconst spin: SpinnerResult
spin.SpinnerResult.stop(msg?: string): void
stop('Completed successfully');
// Or cancel - shows red square// spin.cancel('Operation cancelled');
// Or error - shows yellow triangle// spin.error('An error occurred');
// Or clear - stops without showing any message// spin.clear();You can also check if the spinner was cancelled via SIGINT (Ctrl+C):
import { const spinner: ({ indicator, onCancel, output, cancelMessage, errorMessage, frames, delay, signal, ...opts }?: SpinnerOptions) => SpinnerResult
spinner } from '@clack/prompts';
const const spin: SpinnerResult
spin = function spinner({ indicator, onCancel, output, cancelMessage, errorMessage, frames, delay, signal, ...opts }?: SpinnerOptions): SpinnerResult
spinner({ SpinnerOptions.onCancel?: () => void
onCancel: () => { var console: Console
The console module provides a simple debugging console that is similar to the
JavaScript console mechanism provided by web browsers.
The module exports two specific components:
- A
Console class with methods such as console.log(), console.error() and console.warn() that can be used to write to any Node.js stream.
- A global
console instance configured to write to process.stdout and
process.stderr. The global console can be used without importing the node:console module.
Warning: The global console object's methods are neither consistently
synchronous like the browser APIs they resemble, nor are they consistently
asynchronous like all other Node.js streams. See the note on process I/O for
more information.
Example using the global console:
console.log('hello world');// Prints: hello world, to stdoutconsole.log('hello %s', 'world');// Prints: hello world, to stdoutconsole.error(new Error('Whoops, something bad happened'));// Prints error message and stack trace to stderr:// Error: Whoops, something bad happened// at [eval]:5:15// at Script.runInThisContext (node:vm:132:18)// at Object.runInThisContext (node:vm:309:38)// at node:internal/process/execution:77:19// at [eval]-wrapper:6:22// at evalScript (node:internal/process/execution:76:60)// at node:internal/main/eval_string:23:3
const name = 'Will Robinson';console.warn(`Danger ${name}! Danger!`);// Prints: Danger Will Robinson! Danger!, to stderr
Example using the Console class:
const out = getStreamSomehow();const err = getStreamSomehow();const myConsole = new console.Console(out, err);
myConsole.log('hello world');// Prints: hello world, to outmyConsole.log('hello %s', 'world');// Prints: hello world, to outmyConsole.error(new Error('Whoops, something bad happened'));// Prints: [Error: Whoops, something bad happened], to err
const name = 'Will Robinson';myConsole.warn(`Danger ${name}! Danger!`);// Prints: Danger Will Robinson! Danger!, to err
console.Console.log(message?: any, ...optionalParams: any[]): void
Prints to stdout with newline. Multiple arguments can be passed, with the
first used as the primary message and all additional used as substitution
values similar to printf(3)
(the arguments are all passed to util.format()).
const count = 5;console.log('count: %d', count);// Prints: count: 5, to stdoutconsole.log('count:', count);// Prints: count: 5, to stdout
See util.format() for more information.
log('User pressed Ctrl+C'); }});

Internationalization
Section titled “Internationalization”The prompts package supports internationalization through the updateSettings function. You can customize the messages used by various prompts to match your preferred language.
import { function updateSettings(updates: ClackSettings): void
updateSettings, const select: <Value>(opts: SelectOptions<Value>) => Promise<Value | symbol>
select, const cancel: (message?: string, opts?: CommonOptions) => void
The cancel function defines an interruption of an interaction
and therefore its end.
cancel } from '@clack/prompts';

updateSettings({ ClackSettings.messages?: { cancel?: string; error?: string;}
Custom messages for prompts
messages: { cancel?: string
Custom message to display when a spinner is cancelled
cancel: "Operación cancelada", error?: string
Custom message to display when a spinner encounters an error

Stream
Section titled “Stream”The stream utilities allow you, like the log utilities, to add semantic contextual information during an interaction,
except that the message contains an unknown number of lines.
Each function renders with specific styling to communicate status.
import { const stream: { message: (iterable: Iterable<string> | AsyncIterable<string>, { symbol }?: LogMessageOptions) => Promise<void>; info: (iterable: Iterable<string> | AsyncIterable<string>) => Promise<void>; ... 4 more ...; error: (iterable: Iterable<string> | AsyncIterable<string>) => Promise<void>;}
stream } from "@clack/prompts";import * as module "node:fs"
fs from "node:fs";
await const stream: { message: (iterable: Iterable<string> | AsyncIterable<string>, { symbol }?: LogMessageOptions) => Promise<void>; info: (iterable: Iterable<string> | AsyncIterable<string>) => Promise<void>; ... 4 more ...; error: (iterable: Iterable<string> | AsyncIterable<string>) => Promise<void>;}
stream.message: (iterable: Iterable<string> | AsyncIterable<string>, { symbol }?: LogMessageOptions) => Promise<void>
message(module "node:fs"
fs.function createReadStream(path: fs.PathLike, options?: BufferEncoding | ReadStreamOptions): fs.ReadStream
options can include start and end values to read a range of bytes from
the file instead of the entire file. Both start and end are inclusive and
start counting at 0, allowed values are in the
[0, Number.MAX_SAFE_INTEGER] range. If fd is specified and start is
omitted or undefined, fs.createReadStream() reads sequentially from the
current file position. The encoding can be any one of those accepted by Buffer.
If fd is specified, ReadStream will ignore the path argument and will use
the specified file descriptor. This means that no 'open' event will be
emitted. fd should be blocking; non-blocking fds should be passed to net.Socket.
If fd points to a character device that only supports blocking reads
(such as keyboard or sound card), read operations do not finish until data is
available. This can prevent the process from exiting and the stream from
closing naturally.
By default, the stream will emit a 'close' event after it has been
destroyed. Set the emitClose option to false to change this behavior.
By providing the fs option, it is possible to override the corresponding fs implementations for open, read, and close. When providing the fs option,
an override for read is required. If no fd is provided, an override for open is also required. If autoClose is true, an override for close is
also required.
import { createReadStream } from 'node:fs';
// Create a stream from some character device.const stream = createReadStream('/dev/input/event0');setTimeout(() => { stream.close(); // This may not close the stream. // Artificially marking end-of-stream, as if the underlying resource had // indicated end-of-file by itself, allows the stream to close. // This does not cancel pending read operations, and if there is such an // operation, the process may still not be able to exit successfully // until it finishes. stream.push(null); stream.read(0);}, 100);
If autoClose is false, then the file descriptor won't be closed, even if
there's an error. It is the application's responsibility to close it and make
sure there's no file descriptor leak. If autoClose is set to true (default
behavior), on 'error' or 'end' the file descriptor will be closed
automatically.
mode sets the file mode (permission and sticky bits), but only if the
file was created.
An example to read the last 10 bytes of a file which is 100 bytes long:
import { createReadStream } from 'node:fs';
createReadStream('sample.txt', { start: 90, end: 99 });
If options is a string, then it specifies the encoding.
createReadStream('./banner.txt', { StreamOptions.encoding?: BufferEncoding | undefined
encoding: 'utf-8' }));await const stream: { message: (iterable: Iterable<string> | AsyncIterable<string>, { symbol }?: LogMessageOptions) => Promise<void>; info: (iterable: Iterable<string> | AsyncIterable<string>) => Promise<void>; ... 4 more ...; error: (iterable: Iterable<string> | AsyncIterable<string>) => Promise<void>;}

This function returns a formatted text considering the format passed
for printing in a terminal. It is aware of the terminal's capabilities
and acts according to the configuration set via NO_COLOR,
NODE_DISABLE_COLORS and FORCE_COLOR environment variables.

util.inspect.colors also provides text formats such as italic, and
underline and you can combine both:
console.log( util.styleText(['underline', 'italic'], 'My italic underlined message'),);
When passing an array of formats, the order of the format applied
is left to right so the following style might overwrite the previous one.
