## Usage
```js
import { file, dir, write } from 'opfs-tools';
// --------- Create / Write ---------
await dir('/test-dir').create(); // create a directory
await write('/dir/file.txt', ''); // empty file
await write('/dir/fetch-file', (await fetch('//example.com')).body);
// inputFile from the input element picked by the user
await write('/dir/input-file', inputFile.stream());
// For incremental file writes, please refer to the API documentation.
const writer = await file('/dir/file').createWriter();
// --------- Read ---------
await file('/dir/file.txt').text();
await file('/dir/input-file').arrayBuffer();
await file('/dir/input-file').stream();
// If you want to read file fragments, please refer to the API documentation.
const reader = await file('/dir/input-file').createReader();
await dir('/test-dir').children();
// --------- Remove ---------
await dir('/test-dir').remove();
await file('/dir/file.txt').remove();
// --------- copyTo / moveTo ---------
await file('/dir/file').copyTo(file('/dir/file copy1'));
await dir('/dir').moveTo(dir('/.Trash'));
// --------- import/export file -----------
const [impHandle] = await window.showOpenFilePicker();
write('/import-file', (await impHandle.getFile()).stream());
const expHandle = await window.showSaveFilePicker({
suggestedName: `opfs-export-file`,
});
(await file('/export-file').stream()).pipeTo(await expHandle.createWritable());
// --------- upload -------------
const formData = new FormData();
formData.append('file', await file('/upload-file').getOriginFile());
await fetch('/upload', {
method: 'post',
headers: { 'Content-Type': 'multipart/form-data' },
body: formData,
});
