### Generating Random Spinners in JavaScript

Source: https://context7.com/sindresorhus/cli-spinners/llms.txt

Shows how to use the `randomSpinner` function from `cli-spinners` to get a random spinner configuration. It then demonstrates implementing a basic animation using this random spinner, similar to other examples. Requires Node.js.

```javascript
import {randomSpinner} from 'cli-spinners';
import process from 'node:process';

// Get a random spinner
const spinner = randomSpinner();
console.log(spinner);
// Example output (varies each run):
// {
//   interval: 80,
//   frames: ['⠋', '⠙', '⠹', '⠸', '⠼', '⠴', '⠦', '⠧', '⠇', '⠏']
// }

// Use in an animation
let frameIndex = 0;
const interval = setInterval(() => {
  const frame = spinner.frames[frameIndex];
  process.stdout.write(`\r${frame} Random animation!`);
  frameIndex = (frameIndex + 1) % spinner.frames.length;
}, spinner.interval);

// Clean up after 2 seconds
setTimeout(() => {
  clearInterval(interval);
  process.stdout.write('\r✓ Complete!      \n');
}, 2000);
```

Provides a JavaScript code snippet to enumerate all available spinner names exported by the `cli-spinners` library. It uses `Object.keys()` to get an array of names and then prints them. Requires Node.js.

```javascript
import cliSpinners from 'cli-spinners';

// Get all spinner names
const spinnerNames = Object.keys(cliSpinners);
console.log(`Available spinners (${spinnerNames.length} total):`);
console.log(spinnerNames.join(', '));

### Get a Random Spinner using JavaScript

Source: https://github.com/sindresorhus/cli-spinners/blob/main/readme.md

Import the 'randomSpinner' function from the cli-spinners library to get a randomly selected spinner. The output demonstrates the structure of a spinner object, similar to accessing a specific one.

```javascript
import {randomSpinner} from 'cli-spinners';

console.log(randomSpinner());
/*
{
	interval: 80,
	frames: ['⠋', '⠙', '⠹', '⠸', '⠼', '⠴', '⠦', '⠧', '⠇', '⠏']
}
*/
```

### Interactive Spinner Demo with Node.js

Source: https://context7.com/sindresorhus/cli-spinners/llms.txt

Creates an interactive demo that cycles through all available spinners with user control. It uses Node.js built-in modules like 'process' and 'readline', along with the 'log-update' library for flicker-free rendering. User input (Enter key) advances to the next spinner, and Ctrl+C exits the application.

```javascript
import process from 'node:process';
import readline from 'node:readline';
import logUpdate from 'log-update';
import cliSpinners from 'cli-spinners';

const spinners = Object.keys(cliSpinners);
let frame = 0;
let spinner = 0;
let frameInterval;
let spinnerTimeout;

const showNextFrame = () => {
  const {frames} = cliSpinners[spinners[spinner]];
  logUpdate(frames[frame++ % frames.length] + ' ' + spinners[spinner]);
};

const showNextSpinner = () => {
  if (frameInterval) {
    clearInterval(frameInterval);
    spinner++;
  }

  if (spinner < spinners.length) {
    const s = cliSpinners[spinners[spinner]];
    frameInterval = setInterval(showNextFrame, s.interval);
    spinnerTimeout = setTimeout(showNextSpinner, Math.max(s.interval * s.frames.length, 1000));
  } else {
    process.exit(0);
  }
};

// Setup keyboard controls
readline.emitKeypressEvents(process.stdin);
process.stdin.setRawMode(true);

process.stdin.on('keypress', (string_, key) => {
  if (key.ctrl && key.name === 'c') {
    process.exit(130);
  }

  // Press Enter to skip to next spinner
  if (key.name === 'return' && spinnerTimeout) {
    clearTimeout(spinnerTimeout);
    showNextSpinner();
  }
});

console.log(`${spinners.length} spinners\n`);
showNextSpinner();

```

### Implementing a Basic Spinner Animation in JavaScript

Source: https://context7.com/sindresorhus/cli-spinners/llms.txt

Shows how to create a functional terminal spinner animation using `setInterval` and the `cli-spinners` data. It updates the terminal output in place using `process.stdout.write` and stops after a specified duration. Requires Node.js.

```javascript
import process from 'node:process';
import cliSpinners from 'cli-spinners';

// Simple spinner animation (without log-update)
const spinner = cliSpinners.dots;
let frameIndex = 0;

const interval = setInterval(() => {
  const frame = spinner.frames[frameIndex];
  process.stdout.write(`\r${frame} Loading...`);
  frameIndex = (frameIndex + 1) % spinner.frames.length;
}, spinner.interval);

// Stop after 3 seconds
setTimeout(() => {
  clearInterval(interval);
  process.stdout.write('\r✓ Done!          \n');
}, 3000);
```

--------------------------------

### Accessing Specific Spinners in JavaScript

Source: https://context7.com/sindresorhus/cli-spinners/llms.txt

Demonstrates how to import and access individual spinner configurations (frames and interval) from the `cli-spinners` library in JavaScript. This allows direct use of predefined animations like 'dots', 'line', or 'bouncingBall'.

```javascript
import cliSpinners from 'cli-spinners';

// Access the 'dots' spinner
const spinner = cliSpinners.dots;
console.log(spinner);
// Output:
// {
//   interval: 80,
//   frames: ['⠋', '⠙', '⠹', '⠸', '⠼', '⠴', '⠦', '⠧', '⠇', '⠏']
// }

// Use different spinners
console.log(cliSpinners.line);
// { interval: 130, frames: ['-', '\\', '|', '/'] }

console.log(cliSpinners.bouncingBall);
// { interval: 80, frames: ['( ●    )', '(  ●   )', '(   ●  )', '(    ● )', '(     ●)', '(    ● )', '(   ●  )', '(  ●   )', '( ●    )', '(●     )'] }
```

--------------------------------

### Direct JSON Access for Custom Spinner Processing

Source: https://context7.com/sindresorhus/cli-spinners/llms.txt

Shows how to access the raw spinner data directly from the 'spinners.json' file using dynamic import with the 'json' type. This allows for custom processing, filtering, and sorting of spinners based on their properties like interval speed and frame count.

```javascript
import spinners from './spinners.json' with {type: 'json'};

// Direct JSON access
console.log(spinners.dots);
// { interval: 80, frames: ['⠋', '⠙', '⠹', '⠸', '⠼', '⠴', '⠦', '⠧', '⠇', '⠏'] }

// Filter spinners by interval speed
const fastSpinners = Object.entries(spinners)
  .filter(([name, config]) => config.interval < 100)
  .map(([name]) => name);
console.log('Fast spinners:', fastSpinners);

// Find spinners with most frames
const complex = Object.entries(spinners)
  .sort((a, b) => b[1].frames.length - a[1].frames.length)
  .slice(0, 5)
  .map(([name, config]) => ({name, frameCount: config.frames.length}));
console.log('Most complex spinners:', complex);

```

--------------------------------

### TypeScript Integration for Type-Safe Spinners

Source: https://context7.com/sindresorhus/cli-spinners/llms.txt

Demonstrates how to use TypeScript definitions for type-safe spinner access and autocomplete support. It shows how to access spinner properties like 'interval' and 'frames' and utilize the 'randomSpinner' function. A 'displaySpinner' function is provided for type-safe spinner rendering.

```typescript
import cliSpinners, {randomSpinner, Spinner, SpinnerName} from 'cli-spinners';

// Type-safe spinner access
const spinnerName: SpinnerName = 'dots';
const spinner: Spinner = cliSpinners[spinnerName];

// Spinner object has typed properties
console.log(spinner.interval); // number
console.log(spinner.frames);   // string[]

// randomSpinner returns Spinner type
const random: Spinner = randomSpinner();

// Function to display any spinner with type safety
function displaySpinner(name: SpinnerName, message: string): void {
  const spinner = cliSpinners[name];
  let index = 0;

  const interval = setInterval(() => {
    const frame = spinner.frames[index];
    process.stdout.write(`\r${frame} ${message}`);
    index = (index + 1) % spinner.frames.length;
  }, spinner.interval);

  setTimeout(() => {
    clearInterval(interval);
    process.stdout.write('\r✓ Done!\n');
  }, 3000);
}

displaySpinner('earth', 'Saving planet...');

```

--------------------------------

### Access a Specific Spinner (dots) using JavaScript

Source: https://github.com/sindresorhus/cli-spinners/blob/main/readme.md

Import the cli-spinners library and access a specific spinner, such as 'dots'. The output shows the structure of a spinner object, including its interval and frames. This is useful for custom spinner implementations.

```javascript
import cliSpinners from 'cli-spinners';

console.log(cliSpinners.dots);
/*
{
	interval: 80,
	frames: ['⠋', '⠙', '⠹', '⠸', '⠼', '⠴', '⠦', '⠧', '⠇', '⠏']
}
*/
```

--------------------------------

### Animating Spinners with log-update in JavaScript

Source: https://context7.com/sindresorhus/cli-spinners/llms.txt

Integrates `cli-spinners` with the `log-update` package to provide flicker-free terminal spinner animations. It allows selecting a spinner by command-line argument or defaults to 'dots'. Requires Node.js and `log-update` package.

```javascript
import logUpdate from 'log-update';
import cliSpinners from 'cli-spinners';

// Choose spinner from command line argument or default to 'dots'
const spinnerName = process.argv[2] || 'dots';
const spinner = cliSpinners[spinnerName];
let index = 0;

setInterval(() => {
  const {frames} = spinner;
  logUpdate(frames[index = ++index % frames.length] + ' Processing unicorns...');
}, spinner.interval);

// Usage: node script.js dots
// Usage: node script.js arrow
// Usage: node script.js earth
```
