Unstable
Usage in Deno
```typescript import { openAsBlob } from "node:node__fs.d.ts"; ```
openAsBlob(path: PathLike,options?: OpenAsBlobOptions,): Promise<Blob>
Returns a `Blob` whose data is backed by the given file.
The file must not be modified after the `Blob` is created. Any modifications
will cause reading the `Blob` data to fail with a `DOMException` error.
Synchronous stat operations on the file when the `Blob` is created, and before
each read in order to detect whether the file data has been modified on disk.
```js
import { openAsBlob } from 'node:fs';
const blob = await openAsBlob('the.file.txt');
const ab = await blob.arrayBuffer();
blob.stream();
```
