Description

This plugin provides Security-focused ESLint plugin. By using this plugin, you can proactively identify and mitigate security risks across your entire codebase.

Philosophy

Interlace fosters strength through integration. Instead of stacking isolated rules, we interlace security directly into your workflow to create a resilient fabric of code. We believe tools should guide rather than gatekeep, providing educational feedback that strengthens the developer with every interaction.

⚙️ Configuration Presets

| Preset | Description | | :------------ | :---------------------------------------------- | | recommended | Balanced operability checks for production code |

🏢 Usage Example

// eslint.config.js
import operability from 'eslint-plugin-operability';

export default [
  operability.configs.recommended,

  // Be extra strict in production code
  {
    files: ['src/**/*.ts'],
    ignores: ['**/*.test.ts', '**/*.spec.ts'],
    rules: {
      'operability/no-console-log': 'error',
    },
  },
];

Why These Rules?

no-console-log

console.log statements are for debugging and shouldn't ship to production.

// ❌ Bad: Debug logging in production
function processPayment(card: Card) {
  console.log('Processing payment:', card); // Exposes sensitive data!
  return paymentService.charge(card);
}

// ✅ Good: Use proper logging
function processPayment(card: Card) {
  logger.info('Processing payment', { cardLast4: card.last4 });
  return paymentService.charge(card);
}

no-debug-code-in-production

Catches debugger statements and debug-only code paths.

// ❌ Bad: Debugger statement left in code
function calculateTotal(items: Item[]) {
  debugger; // Will pause execution in production!
  return items.reduce((sum, item) => sum + item.price, 0);
}

// ✅ Good: No debug statements
function calculateTotal(items: Item[]) {
  return items.reduce((sum, item) => sum + item.price, 0);
}

no-verbose-error-messages

Prevents detailed error messages that could expose system internals.

// ❌ Bad: Verbose error exposes internals (CWE-209)
throw new Error(
  `Database connection failed at ${host}:${port} with user ${dbUser}`,
);

// ✅ Good: Generic error with internal logging
logger.error('Database connection failed', { host, port, user: dbUser });
throw new Error('Service temporarily unavailable');
