eslint-plugin-modularity

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 DDD and architecture enforcement  |
|

strict

      | All rules as errors for strict enforcement |
---
🏢 Usage Example

js
// eslint.config.js
import modularity from 'eslint-plugin-modularity';
export default [
  modularity.configs.recommended,

// Apply strict DDD enforcement to domain layer { files: ['src/domain/*/.ts'], ...modularity.configs.strict, }, ];`

`Why These Rules?`


$3
Detects domain entities that are just data containers without behavior — a common anti-pattern.

`ts // ❌ Bad: Anemic model, no behavior class Order { id: string; items: OrderItem[]; status: OrderStatus; }

// ✅ Good: Rich domain model with behavior class Order { id: string; private items: OrderItem[]; private status: OrderStatus;

addItem(item: OrderItem): void { / ... / } submit(): void { / ... / } cancel(reason: string): void { / ... / } }`

`$3`

Value objects should be immutable. This rule catches mutable value objects.

`ts // ❌ Bad: Mutable value object class Money { amount: number; // Can be mutated! }

// ✅ Good: Immutable value object class Money { readonly amount: number; readonly currency: string;

add(other: Money): Money { return new Money(this.amount + other.amount, this.currency); } }`

`$3`

Utility modules should be pure functions without side effects like API calls.

`ts // ❌ Bad: Utils with external dependencies // src/utils/formatters.ts import axios from 'axios';

export async function fetchAndFormat(id: string) { const data = await axios.get(/api/${id}); // External API call! return format(data); }

// ✅ Good: Pure utility function export function format(data: Data): FormattedData { return { / pure transformation / }; }`
