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 reliability checks for most projects |

🏢 Usage Example

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

export default [reliability.configs.recommended];

Why These Rules?

no-silent-errors

Empty catch blocks hide errors, making debugging impossible.

// ❌ Bad: Silent error swallowing
try {
  await processPayment(order);
} catch (e) {
  // Error is silently ignored!
}

// ✅ Good: Handle or log the error
try {
  await processPayment(order);
} catch (e) {
  logger.error('Payment processing failed', { orderId: order.id, error: e });
  throw new PaymentError('Payment failed', { cause: e });
}

no-missing-null-checks

Catches potential null or undefined dereferences.

// ❌ Bad: Potential runtime error
function greet(user: User | null) {
  return `Hello, ${user.name}`; // TypeError if user is null!
}

// ✅ Good: Null-safe access
function greet(user: User | null) {
  return user ? `Hello, ${user.name}` : 'Hello, guest';
}

require-network-timeout

Network requests without timeouts can hang indefinitely.

// ❌ Bad: No timeout, can hang forever
const response = await fetch('/api/data');

// ✅ Good: Request with timeout
const controller = new AbortController();
const timeoutId = setTimeout(() => controller.abort(), 5000);

const response = await fetch('/api/data', {
  signal: controller.signal,
});
clearTimeout(timeoutId);

no-await-in-loop

Sequential awaits in loops cause N+1 performance issues.

// ❌ Bad: Sequential requests (slow)
for (const id of userIds) {
  const user = await fetchUser(id); // N sequential requests
  results.push(user);
}

// ✅ Good: Parallel requests (fast)
const results = await Promise.all(userIds.map((id) => fetchUser(id)));
