ora
Add terminal spinners with Ora. Use when showing loading indicators in CLI tools, displaying progress during async operations, or building polished command-line interfaces with status feedback.
What this skill does
# Ora
## Overview
Ora creates elegant terminal spinners. Show progress during async operations (API calls, file processing, builds), then succeed/fail with a final status. Used by create-next-app, Vercel CLI, Angular CLI.
## Instructions
### Step 1: Basic Spinner
```typescript
import ora from 'ora'
const spinner = ora('Installing dependencies...').start()
try {
await exec('npm install')
spinner.succeed('Dependencies installed')
} catch (err) {
spinner.fail('Installation failed')
process.exit(1)
}
```
### Step 2: Multi-Step Operations
```typescript
async function deploy(env: string) {
const spinner = ora()
spinner.start('Building project...')
await build()
spinner.succeed('Build complete')
spinner.start('Running tests...')
const results = await runTests()
spinner.succeed(`${results.passed} tests passed`)
spinner.start(`Deploying to ${env}...`)
const url = await deployToCloud(env)
spinner.succeed(`Deployed to ${url}`)
spinner.start('Verifying deployment...')
await healthCheck(url)
spinner.succeed('Deployment verified ✓')
}
```
### Step 3: With Other Libraries
```typescript
import ora from 'ora'
import chalk from 'chalk'
const spinner = ora({
text: 'Processing files...',
color: 'cyan',
spinner: 'dots', // or 'line', 'arc', 'bouncingBar'
})
spinner.start()
spinner.text = `Processing ${chalk.bold('image-001.png')}...`
// ... after processing
spinner.text = `Processing ${chalk.bold('image-002.png')}...`
spinner.stopAndPersist({
symbol: chalk.green('✓'),
text: `Processed ${chalk.bold('42')} files in ${chalk.gray('3.2s')}`,
})
```
## Guidelines
- `succeed()` / `fail()` / `warn()` / `info()` stop the spinner with a status icon.
- `stopAndPersist()` for custom symbols/text when the built-in statuses don't fit.
- Update `spinner.text` during long operations to show progress.
- Ora is ESM-only since v6. Use `import ora from 'ora'`.
- In CI environments, ora falls back to static text (no animation).
