Ora
Elegant terminal spinner library for Node.js CLI applications. Displays animated loading spinners with text in the terminal during async operations. Supports multiple spinner styles (dots, line, arc, etc.), success/failure/warning state changes with icons, persistent lines, and concurrent spinner management with ora.all(). Ora v8+ is ESM-only. The go-to library for CLI UX feedback in Node.js tools like deployment scripts, build tools, and agent CLIs.

⚙ Agent Friendliness
🔒 Security
Terminal UI library — no network, no secrets, no auth. Zero security surface area.
⚡ Reliability
Best When
You're building Node.js CLI tools that have async operations (network calls, file processing) and want to show professional terminal spinners with status feedback.
Avoid When
You're running in CI/CD environments where spinner output isn't useful, or need actual percentage-based progress bars (use cli-progress).
Use Cases
- • Show loading spinners during long async operations in Node.js CLIs (API calls, file processing, installs) to communicate progress to users
- • Indicate success/failure state after operations complete with spinner.succeed() or spinner.fail() with colored output
- • Display multiple concurrent operation statuses in CLI tools using separate spinner instances for parallel tasks
- • Build professional-looking CLI tools with terminal UX that communicates operation state without verbose logging
- • Show indeterminate progress for agent operations where duration is unknown (LLM calls, file uploads)
Not For
- • Web applications — Ora is terminal-only; use CSS animations or progress bars for web UIs
- • Deterministic progress bars — use cli-progress for percentage-based progress tracking
- • Non-interactive terminals (CI/CD) — Ora detects TTY and disables animations automatically, but consider this in CI output

Known Gotchas
- ⚠ Ora v8+ is ESM-only — cannot require() in CommonJS; use v7 for CJS compatibility or migrate to ESM
- ⚠ Console.log during active spinner corrupts terminal output — use spinner.text to update text, or spinner.stop() before logging, or use spinner.info()/warn() for inline messages
- ⚠ Ora auto-disables in non-TTY environments (CI/CD pipes) — check isEnabled flag if you need different behavior in CI vs terminal
- ⚠ Spinner persistence with persistSpinners option must be configured for final state to remain visible after stop() — by default spinner is replaced by succeed/fail symbol
- ⚠ Import path changed in v8: use 'ora' not 'ora/index.js' — some older code uses path-specific imports that broke in the ESM-only version
- ⚠ When using multiple concurrent spinners, they each manage their own terminal line — on narrow terminals or when too many spinners run simultaneously, output can become cluttered
