🤏 Only 4 kB gzip (80% smaller than prompts)
💎 Beautiful, minimal UI
✅ Simple API
🧱 Comes with text, confirm, select, and spinner components

Basics

Setup

The intro and outro functions will print a message to begin or end a prompt session, respectively.

import { intro, outro } from "@clack/prompts";

intro(`create-my-app`);
// Do stuff
outro(`You're all set!`);

Cancellation

The isCancel function is a guard that detects when a user cancels a question with CTRL + C. You should handle this situation for each prompt, optionally providing a nice cancellation message with the cancel utility.

import { isCancel, cancel, text } from "@clack/prompts";

const value = await text(/* TODO */);

if (isCancel(value)) {
  cancel("Operation cancelled.");
  process.exit(0);
}

Components

Text

The text component accepts a single line of text.

import { text } from "@clack/prompts";

const meaning = await text({
  message: "What is the meaning of life?",
  placeholder: "Not sure",
  validate(value) {
    if (value.length === 0) return `Value is required!`;
  },
});

Confirm

The confirm component accepts a yes or no answer. The result is a boolean value of true or false.

import { confirm } from "@clack/prompts";

const shouldContinue = await confirm({
  message: "Do you want to continue?",
});

Select

The select component allows a user to choose one value from a list of options. The result is the value prop of a given option.

import { select } from "@clack/prompts";

const projectType = await select({
  message: "Pick a project type.",
  options: [
    { value: "ts", label: "TypeScript" },
    { value: "js", label: "JavaScript" },
    { value: "coffee", label: "CoffeeScript", hint: "oh no" },
  ],
});

Spinner

The spinner component surfaces a pending action, such as a long-running download or dependency installation.

import { spinner } from "@clack/prompts";

const s = spinner();
s.start("Installing via npm");
// Do installation
s.stop("Installed via npm");
