💡 Real-World Examples

Creating a Logger with Color-Coded Severity

import * as consolecolor from '@push.rocks/consolecolor';

class ColorLogger {
  info(message: string) {
    console.log(consolecolor.coloredString(`ℹ INFO: ${message}`, 'cyan'));
  }
  
  success(message: string) {
    console.log(consolecolor.coloredString(`✔ SUCCESS: ${message}`, 'green'));
  }
  
  warning(message: string) {
    console.log(consolecolor.coloredString(`⚠ WARNING: ${message}`, 'orange', 'black'));
  }
  
  error(message: string) {
    console.log(consolecolor.coloredString(`✖ ERROR: ${message}`, 'red', 'white'));
  }
}

const logger = new ColorLogger();
logger.info('Application started');
logger.success('Database connected');
logger.warning('Memory usage above 80%');
logger.error('Failed to write to disk');

Progress Indicator with Colors

import * as consolecolor from '@push.rocks/consolecolor';

function showProgress(step: number, total: number, status: 'pending' | 'running' | 'done') {
  const percentage = Math.round((step / total) * 100);
  const progressBar = '█'.repeat(percentage / 5) + '░'.repeat(20 - percentage / 5);
  
  let statusColor: 'orange' | 'blue' | 'green' = 'orange';
  if (status === 'running') statusColor = 'blue';
  if (status === 'done') statusColor = 'green';
  
  const output = consolecolor.coloredString(
    `[${progressBar}] ${percentage}% - ${status}`,
    statusColor
  );
  
  process.stdout.write('\r' + output);
}

// Usage
showProgress(5, 10, 'running');

Colorful Data Table

import * as consolecolor from '@push.rocks/consolecolor';

function printColorfulTable(data: Array<{name: string, status: string, value: number}>) {
  // Header
  console.log(consolecolor.coloredString('━'.repeat(50), 'cyan'));
  console.log(
    consolecolor.coloredString('Name', 'white') + '\t\t' +
    consolecolor.coloredString('Status', 'white') + '\t\t' +
    consolecolor.coloredString('Value', 'white')
  );
  console.log(consolecolor.coloredString('━'.repeat(50), 'cyan'));
  
  // Data rows
  data.forEach(row => {
    const statusColor = row.status === 'active' ? 'green' : 
                       row.status === 'pending' ? 'orange' : 'red';
    const valueColor = row.value > 80 ? 'green' : 
                      row.value > 40 ? 'orange' : 'red';
    
    console.log(
      row.name + '\t\t' +
      consolecolor.coloredString(row.status, statusColor) + '\t\t' +
      consolecolor.coloredString(row.value.toString(), valueColor)
    );
  });
  
  console.log(consolecolor.coloredString('━'.repeat(50), 'cyan'));
}

// Example usage
printColorfulTable([
  { name: 'Service A', status: 'active', value: 95 },
  { name: 'Service B', status: 'pending', value: 60 },
  { name: 'Service C', status: 'failed', value: 15 }
]);

🔧 TypeScript Support

This module is written in TypeScript and provides full type definitions out of the box:

import type { TColorName, IRGB } from '@push.rocks/consolecolor';

// TColorName type for color validation
const myColor: TColorName = 'blue'; // ✅ Valid
// const invalid: TColorName = 'purple'; // ❌ TypeScript error

// IRGB interface for RGB values
const customRGB: IRGB = { r: 5, g: 3, b: 1 }; // Used internally

🎯 Use Cases

• CLI Tools: Make your command-line tools more user-friendly with color-coded output
• Logging Systems: Differentiate log levels with distinct colors
• Build Scripts: Highlight errors, warnings, and success messages
• Development Tools: Color-code test results, linting output, or deployment statuses
• Data Visualization: Create simple colored charts and graphs in the terminal
• Interactive CLIs: Guide users with colored prompts and responses

🚦 Best Practices

1. Use colors consistently - Establish a color scheme (e.g., red for errors, green for success)
2. Consider accessibility - Not everyone can distinguish all colors equally
3. Provide non-color alternatives - Use symbols alongside colors (✔, ✖, ⚠)
4. Test in different terminals - Colors may appear differently across terminal emulators
5. Keep it readable - Avoid color combinations that are hard to read
