Installation

`sh npm install @inquirer/prompts `	`sh yarn add @inquirer/prompts `	`sh pnpm add @inquirer/prompts `	`sh bun add @inquirer/prompts `

> [!NOTE]
> Inquirer recently underwent a rewrite from the ground up to reduce the package size and improve performance. The previous version of the package is still maintained (though not actively developed), and offered hundreds of community contributed prompts that might not have been migrated to the latest API. If this is what you're looking for, the previous package is over here.

Usage

`js
import { input } from '@inquirer/prompts';

const answer = await input({ message: 'Enter your name' });
`

Prompts

Input

!Input prompt

`js
import { input } from '@inquirer/prompts';

See documentation for usage example and options documentation.

Select

!Select prompt

`js
import { select } from '@inquirer/prompts';
`

See documentation for usage example and options documentation.

Checkbox

!Checkbox prompt

`js
import { checkbox } from '@inquirer/prompts';
`

See documentation for usage example and options documentation.

Confirm

!Confirm prompt

`js
import { confirm } from '@inquirer/prompts';
`

See documentation for usage example and options documentation.

Search

!search prompt

`js
import { search } from '@inquirer/prompts';
`

See documentation for usage example and options documentation.

Password

!Password prompt

`js
import { password } from '@inquirer/prompts';
`

See documentation for usage example and options documentation.

Expand

!Expand prompt closed
!Expand prompt expanded

`js
import { expand } from '@inquirer/prompts';
`

See documentation for usage example and options documentation.

Editor

Launches an instance of the users preferred editor on a temporary file. Once the user exits their editor, the content of the temporary file is read as the answer. The editor used is determined by reading the $VISUAL or $EDITOR environment variables. If neither of those are present, the OS default is used (notepad on Windows, vim on Mac or Linux.)

`js
import { editor } from '@inquirer/prompts';
`

See documentation for usage example and options documentation.

Number

Very similar to the input prompt, but with built-in number validation configuration option.

`js
import { number } from '@inquirer/prompts';
`

See documentation for usage example and options documentation.

Raw List

!Raw list prompt

`js
import { rawlist } from '@inquirer/prompts';
`

See documentation for usage example and options documentation.

Create your own prompts

The API documentation is over here, and our testing utilities here.

Advanced usage

All inquirer prompts are a function taking 2 arguments. The first argument is the prompt configuration (unique to each prompt). The second is providing contextual or runtime configuration.

The context options are:

| Property | Type | Required | Description |
| ----------------- | ----------------------- | -------- | ------------------------------------------------------------ |
| input | NodeJS.ReadableStream | no | The stdin stream (defaults to process.stdin) |
| output | NodeJS.WritableStream | no | The stdout stream (defaults to process.stdout) |
| clearPromptOnDone | boolean | no | If true, we'll clear the screen after the prompt is answered |
| signal | AbortSignal | no | An AbortSignal to cancel prompts asynchronously |

> [!WARNING]
> When providing an input stream or piping process.stdin, it's very likely you need to call process.stdin.setRawMode(true)
> before calling inquirer functions. Node.js usually does it automatically, but when we shadow the stdin, Node can loss track
> and not know it has to. If the prompt isn't interactive (arrows don't work, etc), it's likely due to this.

Example:

`js
import { confirm } from '@inquirer/prompts';

const allowEmail = await confirm(
{ message: 'Do you allow us to send you email?' },
{
output: new Stream.Writable({
write(chunk, _encoding, next) {
// Do something
next();
},
}),
clearPromptOnDone: true,
},
);
`

Canceling prompt

This can be done with either an AbortController or AbortSignal.

`js
// Example 1: using built-in AbortSignal utilities
import { confirm } from '@inquirer/prompts';

const answer = await confirm({ ... }, { signal: AbortSignal.timeout(5000) });
`

`js
// Example 2: implementing custom cancellation with an AbortController
import { confirm } from '@inquirer/prompts';

const controller = new AbortController();
setTimeout(() => {
controller.abort(); // This will reject the promise
}, 5000);

const answer = await confirm({ ... }, { signal: controller.signal });
`

Recipes

Handling ctrl+c gracefully

When a user press ctrl+c to exit a prompt, Inquirer rejects the prompt promise. This is the expected behavior in order to allow your program to teardown/cleanup its environment. When using async/await, rejected promises throw their error. When unhandled, those errors print their stack trace in your user's terminal.

`
ExitPromptError: User force closed the prompt with 0 null
at file://example/packages/core/dist/esm/lib/create-prompt.js:55:20
at Emitter.emit (file://example/node_modules/signal-exit/dist/mjs/index.js:67:19)
at #processEmit (file://example/node_modules/signal-exit/dist/mjs/index.js:236:27)
at #process.emit (file://example/node_modules/signal-exit/dist/mjs/index.js:187:37)
at process.callbackTrampoline (node:internal/async_hooks:130:17)
`

This isn't a great UX, which is why we highly recommend you to handle those errors gracefully.

First option is to wrap your scripts in try/catch; like we do in our demo program. Or handle the error in your CLI framework mechanism; for example Clipanion catch method.

Lastly, you could handle the error globally with an event listener and silence it.

`ts
process.on('uncaughtException', (error) => {
if (error instanceof Error && error.name === 'ExitPromptError') {
console.log('👋 until next time!');
} else {
// Rethrow unknown errors
throw error;
}
});
`

Get answers in an object

When asking many questions, you might not want to keep one variable per answer everywhere. In which case, you can put the answer inside an object.

`js
import { input, confirm } from '@inquirer/prompts';

const answers = {
firstName: await input({ message: "What's your first name?" }),
allowEmail: await confirm({ message: 'Do you allow us to send you email?' }),
};

console.log(answers.firstName);
`

Ask a question conditionally

Maybe some questions depend on some other question's answer.

`js
import { input, confirm } from '@inquirer/prompts';

const allowEmail = await confirm({ message: 'Do you allow us to send you email?' });

let email;
if (allowEmail) {
email = await input({ message: 'What is your email address' });
}
`

Get default value after timeout

`js
import { input } from '@inquirer/prompts';

const answer = await input(
{ message: 'Enter a value (timing out in 5 seconds)' },
{ signal: AbortSignal.timeout(5000) },
).catch((error) => {
if (error.name === 'AbortPromptError') {
return 'Default value';
}

throw error;
});
`

Using as pre-commit/git hooks, or scripts

By default scripts ran from tools like husky/lint-staged might not run inside an interactive shell. In non-interactive shell, Inquirer cannot run, and users cannot send keypress events to the process.

For it to work, you must make sure you start a tty (or "interactive" input stream.)

If those scripts are set within your package.json, you can define the stream like so:

`json
"precommit": "my-script < /dev/tty"
`

Or if in a shell script file, you'll do it like so: (on Windows that's likely your only option)

`sh
#!/bin/sh
exec < /dev/tty

node my-script.js
`

Using with nodemon

When using inquirer prompts with nodemon, you need to pass the --no-stdin flag for everything to work as expected.

`sh
npx nodemon ./packages/demo/demos/password.mjs --no-stdin
`

Note that for most of you, you'll be able to use the new watch-mode built-in Node. This mode works out of the box with inquirer.

`sh


One of depending on your need


node --watch script.js
node --watch-path=packages/ packages/demo/
`

Wait for config

Maybe some question configuration require to await a value.

`js
import { confirm } from '@inquirer/prompts';

const answer = await confirm({ message: await getMessage() });
`

Usage with npx within bash scripts

You can use Inquirer prompts directly in the shell via npx, which is useful for quick scripts or package.json commands.

A community library, @inquirer-cli, exposes each prompt as a standalone CLI.

For example, to prompt for input:

`bash
name=$(npx -y @inquirer-cli/input -r "What is your name?")
echo "Hello, $name!"
`

Or to create an interactive version bump:

`bash
$ npm version $(npx -y @inquirer-cli/select -c patch -c minor -c major 'Select Version')
`
