## Overview

The `@verdaccio/tarball` package provides utilities for converting tarball URLs between remote and local registry formats, and for extracting metadata from tarball archives.

## Installation

```

## Usage

```typescript
import {
  convertDistRemoteToLocalTarballUrls,
  convertDistVersionToLocalTarballsUrl,
  getTarballDetails,
} from '@verdaccio/tarball';

// Convert all remote tarball URLs in a package manifest to local URLs
const localPkg = convertDistRemoteToLocalTarballUrls(pkg, request, urlPrefix);

// Convert a single version's tarball URL
const localVersion = convertDistVersionToLocalTarballsUrl(name, version, request, urlPrefix);

// Extract tarball metadata
const details = await getTarballDetails(tarballBuffer);
// { fileCount: 42, unpackedSize: 102400 }
```
