Search

Use npx -y skilld search instead of grepping .skilld/ directories — hybrid semantic + keyword search across all indexed docs, issues, and releases.

npx -y skilld search "query" -p @clack/prompts
npx -y skilld search "issues:error handling" -p @clack/prompts
npx -y skilld search "releases:deprecated" -p @clack/prompts

Filters: docs:, issues:, releases: prefix narrows by source type.

API Changes

⚠️ ESM-only — v1.0 dropped CJS dual-publish, require('@clack/prompts') no longer works source

⚠️ spinner.stop(msg, 1) / spinner.stop(msg, 2) — v1.0 replaced numeric codes with spinner.cancel(msg) and spinner.error(msg) source

⚠️ suggestion prompt — added then removed in v1.0, use path prompt (autocomplete-based) instead source

⚠️ placeholder in text() — v1.0 changed to visual-only hint, no longer used as tabbable/return value source

✨ autocomplete() / autocompleteMultiselect() — new in v1.0, searchable select with filter option for custom/fuzzy matching source

✨ progress() — new in v1.0, displays a progress bar with start(), stop(), cancel(), error() methods source

✨ taskLog() — new in v1.0, scrolling log output cleared on success; supports group() for nested log sections source

✨ box() — new in v1.0, renders boxed text similar to note source

✨ path() — new in v1.0, autocomplete-based file path prompt source

✨ stream.step() — new in v0.10, renders async iterable message streams (useful for LLM output) source

✨ spinner({ indicator: 'timer' }) — new in v0.10, shows elapsed time instead of dots animation source

✨ updateSettings({ aliases, messages }) — new in v0.9, configures global keybindings and i18n cancel/error messages source

✨ signal option — new in v0.9, all prompts accept AbortSignal for programmatic cancellation source

✨ withGuide option — new in v1.0, disables the default clack border on any prompt source

✨ spinner.clear() — new in v1.0, stops and clears spinner output entirely source

✨ confirm({ vertical: true }) — new in v1.0.1, arranges yes/no options vertically source

Best Practices

✅ Use spinner.cancel() and spinner.error() instead of stop codes — v1.0 replaced stop(msg, code) with distinct methods source

const s = spinner()
s.start('Deploying')
// s.stop('Done')       // success
// s.cancel('Aborted')  // user cancelled (CTRL+C)
// s.error('Failed')    // error occurred
// s.clear()            // stop and clear all output

✅ Pass signal to prompts for programmatic cancellation — all prompts accept AbortSignal since v0.9.0 source

const answer = await confirm({
  message: 'Continue?',
  signal: AbortSignal.timeout(5000),
})

✅ Use group() with onCancel instead of checking isCancel after every prompt — centralizes cancellation handling for multi-step flows source

const result = await p.group({
  name: () => p.text({ message: 'Name?' }),
  lang: () => p.select({ message: 'Language?', options }),
}, {
  onCancel: () => { p.cancel('Cancelled.'); process.exit(0) },
})

✅ Use updateSettings for global i18n messages and key aliases — per-instance options override globals source

import { updateSettings } from '@clack/prompts'
updateSettings({
  aliases: { w: 'up', s: 'down' },
  messages: { cancel: 'Cancelado', error: 'Error' },
})

✅ Use stream instead of log for LLM/async output — accepts sync and async iterables, renders incrementally source

await stream.step((async function* () {
  yield* generateLLMResponse(question)
})())

✅ Use taskLog for subprocess output — renders lines continuously, clears on success, preserves on error source

const tl = taskLog({ title: 'Building' })
for await (const line of buildProcess()) tl.message(line)
success ? tl.success('Done') : tl.error('Failed')

✅ Distinguish placeholder from defaultValue in text() — placeholder is visual-only hint, never returned as value (changed in v1.0); use defaultValue for the fallback return value source

const name = await text({
  message: 'Project name?',
  placeholder: 'my-app',    // visual hint only, NOT returned
  defaultValue: 'my-app',   // returned when user presses Enter without typing
})

✅ v1.0 is ESM-only — CJS require() no longer works; use dynamic import() or switch to ESM source

✅ Guard against empty options arrays in select/multiselect — passing ] throws TypeError: Cannot read properties of undefined [source

✅ Vim keybindings (h/j/k/l) and Escape → cancel are enabled by default since v0.9.0 — updateSettings cannot disable defaults, only add aliases source
