## README

# MVF Fetch

Isomorphic utilities for efficiently reading published MVF v2/v3 zip archives from the cloud via HTTP Range requests.

This package focuses on extracting and optionally validating individual zip entries. It does not render maps or convert between MVF versions.

## Usage

```ts
import { createMvfFetcher } from '@mappedin/mvf-fetch';
import { autoMvfValidator } from '@mappedin/mvf-fetch/validators';

const fetcher = createMvfFetcher({
  url: async () => ({
    url: signedZipUrl,
    cacheKey: `${venueId}:${updatedAt}`,
  }),
  validate: autoMvfValidator(),
});

const version = await fetcher.getVersion();
const { files } = await fetcher.getEntries(['manifest.geojson', 'floors.geojson']);
```
