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 modernization for most projects | | strict | All rules as errors for aggressive modernization |

🏢 Usage Example

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

export default [
  modernization.configs.recommended,

  // Or be strict about modernization
  // modernization.configs.strict,
];

Why These Rules?

no-instanceof-array

instanceof Array fails across different realms (iframes, workers). Array.isArray() is the correct, reliable check.

// ❌ Bad: Fails across realms
if (value instanceof Array) {
}

// ✅ Good: Works everywhere
if (Array.isArray(value)) {
}

prefer-at

Array.at() provides cleaner negative index access (ES2022+).

// ❌ Bad: Verbose negative index access
const last = arr[arr.length - 1];

// ✅ Good: Clean ES2022+ syntax
const last = arr.at(-1);

prefer-event-target

EventTarget is the native browser API and doesn't require Node.js polyfills.

// ❌ Bad: Requires polyfill in browsers
import { EventEmitter } from 'events';

// ✅ Good: Native browser API
const target = new EventTarget();
