Security-focused ESLint plugin.

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

js
// 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?`

$3

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

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

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

`$3`

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

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

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

`$3`

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

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

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