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 change event for an input type file 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);
});

Convert FileSystemFileHandle items to File objects:

import {fromEvent} from 'file-selector';

// Open file picker
const handles = await window.showOpenFilePicker({multiple: true});
// Get the files
const files = await fromEvent(handles);
console.log(files);

NOTE The above is experimental and subject to change.

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:

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