> **Note:** This package is mostly for internal use by Verdaccio and is only intended to be used with Verdaccio 6.x.

## Overview

The `@verdaccio/url` package provides URL validation, manipulation, and protocol detection utilities for the Verdaccio registry. It handles public URL generation, proxy header parsing, and URL prefix normalization.

## Installation

```bash
npm install @verdaccio/url
```

## Usage

```typescript
import {
  combineBaseUrl,
  getPublicUrl,
  getWebProtocol,
  isHost,
  isURLhasValidProtocol,
  validateURL,
  wrapPrefix,
} from '@verdaccio/url';

// Get the public URL for the registry
const publicUrl = getPublicUrl('/verdaccio/', requestOptions);

// Validate URL protocol
isURLhasValidProtocol('https://registry.npmjs.org/'); // true

// Combine base URL components
const baseUrl = combineBaseUrl('https', 'localhost:4873', '/prefix/');
```

### API

- **`getPublicUrl(urlPrefix, requestOptions)`** - Gets public URL from environment variable `VERDACCIO_PUBLIC_URL` or request headers
- **`isURLhasValidProtocol(uri)`** - Checks if URL starts with `http://`, `https://`, or `//`
- **`isHost(url, options)`** - Validates if a string is a valid host
- **`getWebProtocol(headerProtocol, protocol)`** - Detects running protocol from headers (supports HAProxy)
- **`wrapPrefix(prefix)`** - Normalizes URL prefix to `/prefix/` format
- **`combineBaseUrl(protocol, host, prefix)`** - Creates full base registry URL
- **`validateURL(publicUrl)`** - Validates a full URL with protocol
