Usage

---

ES6

Convert a DragEvent to File objects:

import {fromEvent} from 'file-selector';
document.addEventListener('drop', async evt => {
    const files = await fromEvent(evt);
    console.log(files);
});

Convert a file input to File objects:

import {fromEvent} from 'file-selector';
const input = document.getElementById('myInput');
input.addEventListener('change', async evt => {
    const files = await fromEvent(evt);
    console.log(files);
});

CommonJS

Convert a DragEvent to File objects:

const {fromEvent} = require('file-selector');
document.addEventListener('drop', async evt => {
    const files = await fromEvent(evt);
    console.log(files);
});

Browser Support

---

Most browser support basic File selection with drag 'n' drop or file input:

• File API
• Drag Event
• DataTransfer
• <input type="file">

For folder drop we use the FileSystem API which has very limited support:

• DataTransferItem.getAsFile()
• DataTransferItem.webkitGetAsEntry()
• FileSystemEntry
• FileSystemFileEntry.file()
• FileSystemDirectoryEntry.createReader()
• FileSystemDirectoryReader.readEntries()
