# ngWhatsappFormat Angular Pipe

Format WhatsApp-style text in your Angular applications!

This package provides the `NgWhatsappFormatPipe`, a powerful Angular pipe for parsing and rendering WhatsApp-like formatted text (bold, italic, strike, inline code, quotes, and links) as styled HTML.

## Features

- **Bold**, _Italic_, ~Strike-through~, `Inline Code`
- WhatsApp-style > blockquotes
- Recognizes and autolinks URLs and plain domains (`google.com`)
- Injects CSS styles dynamically
- Standalone Angular pipe (Angular 14+ compatible)
- Secure output: only intended for controlled text inputs (trusted sources)

## Installation

```bash
npm install ng-whatsapp-format
```

## Usage

### 1. Import the Pipe

In your Angular module or component:

```typescript
import { NgWhatsappFormatPipe } from "ng-whatsapp-format-pipe";
```

If using the pipe stand-alone (Angular 14+), simply register it in your component:

```typescript
@Component({
  selector: "your-component",
  standalone: true,
  imports: [NgWhatsappFormatPipe],
})
export class YourComponent {}
```

### 2. Use the Pipe in Templates

```html
<div [innerHTML]="yourTextValue | ngWhatsappFormat"></div>
```

> **Tip:** Always bind to `innerHTML` for styled output! Do not use `{{ text | ngWhatsappFormat }}`.
