Package Exports

stylesh
stylesh/dist/cjs/index.js
stylesh/dist/esm/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (stylesh) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

📦 Installation

npm install stylesh

🚀 Quick Start

import 'stylesh';

// Simple colored text
console.log('Hello World'.color('red'));

// Text with background
console.log('Success!'.color('white').bg('green'));

// Bordered text
console.log('Important'.createSolidBorder('blue'));

// Gradient text
console.log('Rainbow Text'.gradient('red'));

// Themed box
console.log('Error Message'.themeBox('error'));

🎯 Getting Started

Two Ways to Use Stylesh

Method 1: Using the StringStyler Class

import { StringStyler } from 'stylesh';

const text = new StringStyler('Hello World')
  .color('cyan')
  .bg('darkBlue')
  .toString();

console.log(text);

Method 2: Using String Extensions (Recommended for Quick Styling)

import 'stylesh';

console.log('Hello World'.color('cyan').bg('darkBlue'));

Note: String extensions are more convenient and the examples below will primarily use this approach.

🎨 Text Colors

Basic Text Coloring

Apply colors to your text using the .color() method:

import 'stylesh';

// Single color
console.log('Red text'.color('red'));
console.log('Blue text'.color('blue'));
console.log('Green text'.color('green'));

Output:

Red text      (in red color)
Blue text     (in blue color)
Green text    (in green color)

🖼️ Background Colors

Basic Background Colors

Apply background colors using the .bg() method:

console.log('White on Red'.color('white').bg('red'));
console.log('Black on Yellow'.color('black').bg('yellow'));
console.log('White on Blue'.color('white').bg('blue'));
console.log('Yellow on Black'.color('yellow').bg('black'));

Output:

White on Red     (white text on red background)
Black on Yellow  (black text on yellow background)
White on Blue    (white text on blue background)
Yellow on Black  (yellow text on black background)

All Background Colors

All the color names that work with .color() also work with .bg():

// Examples
console.log('Text'.bg('darkRed'));
console.log('Text'.bg('lightBlue'));
console.log('Text'.bg('paleGreen'));
console.log('Text'.bg('lavender'));
console.log('Text'.bg('gold'));

🎭 Combining Colors

Text + Background

You can chain .color() and .bg() methods:

console.log('Success Message'.color('white').bg('darkGreen'));
console.log('Error Message'.color('white').bg('darkRed'));
console.log('Warning'.color('black').bg('yellow'));
console.log('Info'.color('white').bg('darkBlue'));

Example Output:

Success Message  (white text on dark green background)
Error Message    (white text on dark red background)
Warning          (black text on yellow background)
Info             (white text on dark blue background)

Creating Highlights

console.log('This is '.color('white') + 'IMPORTANT'.color('yellow').bg('red') + ' information'.color('white'));

Output:

This is IMPORTANT information  (with "IMPORTANT" highlighted in yellow on red)

🌈 Gradients

Text Gradients

Apply gradient colors to your text using predefined color groups:

// Predefined gradient groups
console.log('Red Gradient'.gradient('red'));
console.log('Orange Gradient'.gradient('orange'));
console.log('Yellow Gradient'.gradient('yellow'));
console.log('Green Gradient'.gradient('green'));
console.log('Blue Gradient'.gradient('blue'));
console.log('Purple Gradient'.gradient('purple'));
console.log('Pink Gradient'.gradient('pink'));
console.log('Cyan Gradient'.gradient('cyan'));
console.log('Brown Gradient'.gradient('brown'));
console.log('Gray Gradient'.gradient('gray'));

Output:

Red Gradient     (each character gradually changes through red shades)
Orange Gradient  (each character gradually changes through orange shades)
...

Custom Gradients

Create custom gradients with specific colors:

// Custom color array
console.log('Custom Colors'.gradient(['red', 'orange', 'yellow', 'green', 'blue']));

// Sunset gradient
console.log('Beautiful Sunset'.gradient(['orange', 'coral', 'salmon', 'pink']));

// Ocean gradient
console.log('Deep Ocean Waves'.gradient(['darkBlue', 'blue', 'dodgerBlue', 'skyBlue', 'lightBlue']));

// Fire gradient
console.log('FIRE!'.gradient(['darkRed', 'red', 'orangeRed', 'orange', 'gold']));

How it works: Each character in the text gets colored with the next color in the gradient array, cycling through the colors.

Background Gradients

Apply gradient backgrounds using .bgGradient():

// Predefined background gradient groups
console.log('Background Gradient'.bgGradient('blue'));
console.log('Colorful Background'.bgGradient('purple'));

// Custom background gradient
console.log('Custom BG'.bgGradient(['darkGreen', 'green', 'lime', 'lightGreen']));

Combining Text and Background Gradients

// Text gradient with solid background
console.log('Rainbow on Dark'.gradient('red').bg('black'));

// Solid text with background gradient
console.log('White on Gradient'.color('white').bgGradient('blue'));

📦 Borders

│ Solid Border │
└──────────────┘

Rounded Border

console.log('Rounded Border'.createRoundedBorder());

Output:

╭────────────────╮
│ Rounded Border │
╰────────────────╯

Double Border

console.log('Double Border'.createDoubleBorder());

Output:

╔════════════════╗
║ Double Border  ║
╚════════════════╝

Dashed Border

console.log('Dashed Border'.createDashedBorder());

Output:

+----------------+
| Dashed Border  |
+----------------+

Dotted Border

console.log('Dotted Border'.createDottedBorder());

•••••••••••••••••

Colored Borders

Add color to any border style:

console.log('Red Border'.createSolidBorder('red'));
console.log('Green Border'.createRoundedBorder('green'));
console.log('Blue Border'.createDoubleBorder('blue'));
console.log('Yellow Border'.createDashedBorder('yellow'));
console.log('Cyan Border'.createDottedBorder('cyan'));

Output:

┌────────────┐  (in red)
│ Red Border │
└────────────┘

╭──────────────╮  (in green)
│ Green Border │
╰──────────────╯
...

Borders with Colored Text

Combine text styling with borders:

console.log('Success'.color('white').bg('green').createSolidBorder('green'));
console.log('Error'.color('white').bg('red').createRoundedBorder('red'));
console.log('Warning'.color('black').bg('yellow').createDoubleBorder('orange'));

Output:

┌─────────┐
│ Success │  (white text on green background, green border)
└─────────┘

╭───────╮
│ Error │  (white text on red background, red border)
╰───────╯
...

Multi-line Borders

Borders automatically handle multi-line text:

const multiLine = `Line 1
Line 2
Line 3`;

console.log(multiLine.createSolidBorder('blue'));

Output:

┌────────┐
│ Line 1 │
│ Line 2 │
│ Line 3 │
└────────┘

Custom Border Directions

Control which sides of the border to show:

import { StringStyler } from 'stylesh';

// All sides (default)
console.log(new StringStyler('All Sides').border('solid', 'blue', 'all'));

// Only top and bottom
console.log(new StringStyler('Horizontal').border('solid', 'blue', 'horizontal'));

// Only left and right
console.log(new StringStyler('Vertical').border('solid', 'blue', 'vertical'));

// Only top
console.log(new StringStyler('Top Only').border('solid', 'blue', 'top'));

// Only bottom
console.log(new StringStyler('Bottom Only').border('solid', 'blue', 'bottom'));

// Only left
console.log(new StringStyler('Left Only').border('solid', 'blue', 'left'));

// Only right
console.log(new StringStyler('Right Only').border('solid', 'blue', 'right'));

Output:

┌────────────┐
│ All Sides  │
└────────────┘

┌──────────────┐
  Horizontal
└──────────────┘

│ Vertical │

┌────────────┐
  Top Only

  Bottom Only
└────────────┘

│ Left Only

  Right Only │

Advanced Border Usage with StringStyler

For more control, use the StringStyler class directly:

import { StringStyler } from 'stylesh';

const text = new StringStyler('Custom Border')
  .color('yellow')
  .bg('darkBlue')
  .border('rounded', 'cyan', 'all', 'center');

console.log(text);

🎯 Text Alignment

Alignment Options

When creating borders, you can specify text alignment:

// Center aligned (default)
console.log('Center'.createSolidBorder('blue', 'center'));

// Left aligned
console.log('Left Aligned Text'.createSolidBorder('blue', 'left'));

// Right aligned
console.log('Right Aligned Text'.createSolidBorder('blue', 'right'));

Output:

┌────────┐
│ Center │  (centered)
└────────┘

┌────────────────────┐
│ Left Aligned Text  │  (left aligned)
└────────────────────┘

┌────────────────────┐
│  Right Aligned Text│  (right aligned)
└────────────────────┘

Multi-line Alignment

Alignment works with multi-line text too:

const multiLine = `Short
Medium line
This is a longer line`;

console.log(multiLine.createSolidBorder('green', 'left'));
console.log(multiLine.createSolidBorder('blue', 'center'));
console.log(multiLine.createSolidBorder('red', 'right'));

Output:

┌───────────────────────┐
│ Short                 │
│ Medium line           │
│ This is a longer line │
└───────────────────────┘

┌───────────────────────┐
│        Short          │
│     Medium line       │
│ This is a longer line │
└───────────────────────┘

┌───────────────────────┐
│                 Short │
│           Medium line │
│ This is a longer line │
└───────────────────────┘

🎨 Themes

What are Themes?

Themes are predefined combinations of colors, borders, and styles that you can apply instantly.

Using Built-in Themes

Applying a Theme (without border)

console.log('Success!'.theme('success'));
console.log('Error occurred'.theme('error'));
console.log('Warning message'.theme('warning'));
console.log('Information'.theme('info'));

Output:

Success!         (white text on dark green background)
Error occurred   (white text on dark red background)
Warning message  (black text on yellow background)
Information      (white text on dark blue background)

Applying a Theme with Border (themeBox)

console.log('Success!'.themeBox('success'));
console.log('Error occurred'.themeBox('error'));
console.log('Warning message'.themeBox('warning'));
console.log('Information'.themeBox('info'));

Output:

╭───────────╮
│ Success!  │  (white on dark green with green rounded border)
╰───────────╯

┌─────────────────┐
│ Error occurred  │  (white on dark red with red solid border)
└─────────────────┘

╔═══════════════════╗

// List all available themes
console.log(ThemeManager.listThemes());
// Output: ['error', 'success', 'warning', 'info', 'danger', 'primary', 'secondary', 'rainbow', 'dark', 'light', 'ocean', 'sunset', 'forest']

// Check if a theme exists
console.log(ThemeManager.has('ocean')); // true
console.log(ThemeManager.has('space'));  // false

// Get theme details
const theme = ThemeManager.get('error');
console.log(theme);
// Output: { textColor: 'white', backgroundColor: 'darkRed', borderStyle: 'solid', borderColor: 'red', alignment: 'center' }

// Remove a custom theme
ThemeManager.remove('ocean');

// Clear all custom themes (keeps built-in themes)
ThemeManager.clearCustomThemes();

🎬 Animations

Animation Basics

Stylesh includes a powerful animation system. Import the animator:

import { animator } from 'stylesh';

Important: All animations return a stop function that you can call to stop the animation.

1. Typing Animation

Reveals text character by character, like a typewriter effect:

// Basic typing
await animator.typing('Hello, World!');

// With styling
await animator.typing('Loading complete!', (text) => text.color('green'));

// With options
await animator.typing('Processing...', (text) => text.color('cyan'), {
  speed: 'slow',        // 'slow' | 'normal' | 'fast'
  clearOnComplete: false // Keep text visible after completion
});

Options:

speed: 'slow' (200ms), 'normal' (100ms), 'fast' (50ms)
clearOnComplete: If true, clears the line after animation completes

Example with different speeds:

await animator.typing('Slow typing...', (text) => text.color('red'), { speed: 'slow' });
await animator.typing('Normal typing...', (text) => text.color('yellow'), { speed: 'normal' });
await animator.typing('Fast typing!', (text) => text.color('green'), { speed: 'fast' });

2. Blinking Animation

Makes text blink on and off:

// Basic blinking
const stopBlink = animator.blink('ALERT!');

// With styling
const stopBlink = animator.blink('WARNING', (text) => text.color('red').bg('yellow'));

// With iterations (blink 5 times then stop)
const stopBlink = animator.blink('Notice', (text) => text.color('cyan'), {
  speed: 'fast',
  iterations: 5
});

// Stop after 3 seconds
setTimeout(() => stopBlink(), 3000);

Options:

speed: Animation speed
iterations: Number of times to blink (-1 for infinite, default)

Practical example:

// Alert that blinks 10 times
const stopAlert = animator.blink('🚨 CRITICAL ALERT 🚨', (text) => text.color('yellow').bg('red'), {
  speed: 'fast',
  iterations: 10
});

3. Rainbow Animation

Cycles through rainbow colors:

// Basic rainbow
const stopRainbow = animator.rainbow('Rainbow Text!');

// With speed control
const stopRainbow = animator.rainbow('Colorful', {
  speed: 'normal',
  iterations: 20  // Cycle 20 times
});

// Infinite rainbow (stop manually)
const stopRainbow = animator.rainbow('∞ Infinite Colors ∞', {
  speed: 'fast',
  iterations: -1
});

setTimeout(() => stopRainbow(), 5000); // Stop after 5 seconds

Colors cycled: Red → Orange → Yellow → Green → Cyan → Blue → Purple → Magenta

4. Pulse Animation

Fades between two colors:

// Default pulse (white ↔ gray)
const stopPulse = animator.pulse('Pulsing Text');

// Custom colors
const stopPulse = animator.pulse('Heartbeat', 'red', 'darkRed', {
  speed: 'slow'
});

// Ocean wave effect
const stopPulse = animator.pulse('Ocean Waves', 'cyan', 'blue', {
  speed: 'normal',
  iterations: 15
});

// Breathing effect
const stopPulse = animator.pulse('Breathe...', 'lightBlue', 'darkBlue', {
  speed: 'slow',
  iterations: -1
});

5. Spinner Animation

Shows a loading spinner:

// Basic spinner
const stopSpinner = animator.spinner('Loading...');

// Different messages
const stopSpinner = animator.spinner('Fetching data', { speed: 'fast' });
const stopSpinner = animator.spinner('Processing files', { speed: 'normal' });
const stopSpinner = animator.spinner('Installing packages', { speed: 'slow' });

// Stop after operation completes
setTimeout(() => {
  stopSpinner();
  console.log('Done!'.color('green'));
}, 3000);

Spinner frames: ⠋ ⠙ ⠹ ⠸ ⠼ ⠴ ⠦ ⠧ ⠇ ⠏

Practical example:

async function fetchData() {
  const stopSpinner = animator.spinner('Downloading data...');
  
  // Simulate async operation
  await new Promise(resolve => setTimeout(resolve, 3000));
  
  stopSpinner();
  console.log('✓ Download complete!'.color('green'));
}

fetchData();

6. Progress Bar Animation

Shows a progress bar that fills up:

// Create progress bar updater
const updateProgress = await animator.progressBar(100, {
  width: 40,      // Width of the bar
  char: '█'       // Character to use for filled portion
});

// Update progress
for (let i = 0; i <= 100; i += 10) {
  updateProgress(i);
  await new Promise(resolve => setTimeout(resolve, 200));
}

Output:

████████████░░░░░░░░░░░░░░░░░░ 40%  (updates in place)

Different styles:

// Thin progress bar
const updateProgress = await animator.progressBar(100, {
  width: 20,
  char: '▓'
});

// Block progress bar
const updateProgress = await animator.progressBar(100, {
  width: 50,
  char: '■'
});

Practical example:

async function processFiles(files) {
  const total = files.length;
  const updateProgress = await animator.progressBar(total, {
    width: 40,
    char: '█'
  });
  
  for (let i = 0; i < files.length; i++) {
    // Process file
    await processFile(files[i]);
    updateProgress(i + 1);
  }
  
  console.log('All files processed!'.color('green'));
}

7. Wave Animation

Creates a wave effect across the text:

// Basic wave
const stopWave = animator.wave('Wave Effect!');

// Faster wave
const stopWave = animator.wave('~~ Ocean Waves ~~', {
  speed: 'fast',
  iterations: 30
});

// Slow wave
const stopWave = animator.wave('Smooth Sailing', {
  speed: 'slow',
  iterations: -1
});

setTimeout(() => stopWave(), 5000);

How it works: Each character lights up in cyan as the wave passes through.

8. Matrix Animation

Creates a Matrix-style falling characters effect:

// Basic matrix effect
const stopMatrix = animator.matrix('The Matrix', {
  speed: 'fast',
  iterations: 20
});

// Longer matrix effect
const stopMatrix = animator.matrix('Follow the white rabbit...', {
  speed: 'fast',
  iterations: 50
});

// Stop manually
const stopMatrix = animator.matrix('CODE RAIN', {
  speed: 'fast',
  iterations: -1
});

setTimeout(() => stopMatrix(), 10000);

How it works: Random characters (in green) rapidly replace your text, creating a Matrix-like effect. When stopped, your original text is displayed.

Practical example:

// Hacker-style loading
const stopMatrix = animator.matrix('ACCESSING DATABASE...', {
  speed: 'fast',
  iterations: 30
});

setTimeout(() => {
  stopMatrix();
  console.log('✓ Access granted'.color('green'));
}, 3000);

9. Glitch Animation

Creates a glitch/distortion effect:

// Basic glitch
const stopGlitch = animator.glitch('Glitch Effect');

// Fast glitch
const stopGlitch = animator.glitch('ERROR', {
  speed: 'fast',
  iterations: 15
});

// Slow glitch
const stopGlitch = animator.glitch('System Unstable', {
  speed: 'slow',
  iterations: 10
});

How it works: Text randomly changes colors and positions, creating a glitchy, corrupted appearance. Colors cycle through: red, cyan, magenta, yellow, white.

Practical example:

// Simulate system error
const stopGlitch = animator.glitch('⚠ SYSTEM MALFUNCTION ⚠', {
  speed: 'fast',
  iterations: 20
});

setTimeout(() => {
  stopGlitch();
  console.log('System recovered'.color('green'));
}, 2000);

Stopping All Animations

Stop all running animations at once:

// Start multiple animations
const stop1 = animator.rainbow('Text 1');
const stop2 = animator.pulse('Text 2');
const stop3 = animator.wave('Text 3');

// Stop all at once
animator.stopAll();

Animation Combinations

Combine animations with styling:

// Typing with gradient
await animator.typing('Gradient Typing', (text) => text.gradient('blue'), {
  speed: 'normal'
});

// Blinking with background
const stop = animator.blink('URGENT', (text) => text.color('yellow').bg('red'), {
  speed: 'fast',
  iterations: 10
});

// Pulse with border
const stop = animator.pulse('Loading', 'cyan', 'blue', {
  speed: 'normal'
});

Practical Animation Examples

Loading Sequence

async function loadingSequence() {
  // Typing intro
  await animator.typing('Initializing system...', (text) => text.color('cyan'), {
    speed: 'fast'
  });
  
  // Spinner during operation
  const stopSpinner = animator.spinner('Loading modules', {

Progress Indicator

async function downloadFiles() {
  console.log('Starting download...'.color('cyan'));
  
  const updateProgress = await animator.progressBar(100, {
    width: 50,
    char: '█'
  });
  
  for (let i = 0; i <= 100; i += 5) {
    updateProgress(i);
    await new Promise(resolve => setTimeout(resolve, 100));
  }
  
  console.log('Download complete!'.color('green').createRoundedBorder('green'));
}

downloadFiles();

Alert System

function showAlert(message, type = 'warning') {
  const colors = {
    error: { text: 'white', bg: 'red' },
    warning: { text: 'black', bg: 'yellow' },
    info: { text: 'white', bg: 'blue' }
  };
  
  const { text, bg } = colors[type];
  
  const stop = animator.blink(
    message,
    (text) => text.color(text).bg(bg),
    { speed: 'fast', iterations: 6 }
  );
  
  return stop;
}

// Usage
showAlert('⚠ Low disk space!', 'warning');
showAlert('❌ Connection lost', 'error');
showAlert('ℹ New update available', 'info');

🔧 Advanced Usage

Method Chaining

Chain multiple styling methods together:

console.log(
  'Advanced Styling'
    .color('yellow')
    .bg('darkBlue')
    .createRoundedBorder('cyan')
);

Combining Features

Mix and match all features:

import { StringStyler } from 'stylesh';

// Complex styling
const styled = new StringStyler('Production Server')
  .color('white')
  .bg('darkGreen')
  .border('double', 'green', 'all', 'center');

console.log(styled);

Dynamic Content

Create dynamic styled content:

function createStatusBox(status, message) {
  const themes = {
    online: 'success',
    offline: 'error',
    maintenance: 'warning'
  };
  
  return `[${status.toUpperCase()}] ${message}`.themeBox(themes[status]);
}

console.log(createStatusBox('online', 'Server is running'));
console.log(createStatusBox('offline', 'Server is down'));
console.log(createStatusBox('maintenance', 'Scheduled maintenance'));

Output:

╭──────────────────────────────╮
│ [ONLINE] Server is running   │  (success theme)
╰──────────────────────────────╯

┌──────────────────────────────┐
│ [OFFLINE] Server is down     │  (error theme)
└──────────────────────────────┘

╔════════════════════════════════╗
║ [MAINTENANCE] Scheduled...     ║  (warning theme)
╚════════════════════════════════╝

  console.log();
  
  // Status indicators
  console.log('Status:'.color('cyan').toString().padEnd(20) + 'ONLINE'.color('green'));
  console.log('CPU Usage:'.color('cyan').toString().padEnd(20) + '45%'.color('yellow'));

💡 Tips and Best Practices

Performance Tips

Reuse StringStyler instances when applying the same style multiple times:

const errorStyle = new StringStyler('');
console.log(errorStyle.text = 'Error 1'; errorStyle.theme('error'));
console.log(errorStyle.text = 'Error 2'; errorStyle.theme('error'));

Use string extensions for one-off styling:

console.log('Quick style'.color('red'));

Stop animations when done to free resources:

const stop = animator.rainbow('Text');
// ... later
stop();

Styling Tips

Contrast is key - ensure text is readable:

// Good
console.log('Readable'.color('white').bg('darkBlue'));

// Bad (hard to read)
console.log('Hard to read'.color('yellow').bg('lightYellow'));

Use themes for consistency:

// Consistent error handling
console.log('Error 1'.themeBox('error'));
console.log('Error 2'.themeBox('error'));

Gradients work best with longer text:

// Good
console.log('This is a longer piece of text for gradient'.gradient('blue'));

// Less effective
console.log('Hi'.gradient('blue'));

Debugging Styled Output

If colors don't appear:

Check terminal supports ANSI colors
Test with simple example: console.log('Test'.color('red'))
Some CI/CD environments disable colors
