var file = require('file'); var input = document.querySelector('input'); input.onchange = function(){ var img = file(input.files[0]); if (!img.is('image/*')) { alert('Images only!'); return; } var reader = img.toDataURL(function(err, str){ if (err) throw err; var img = document.createElement('img'); img.src = str; img.height = 300; document.body.appendChild(img); }); reader.on('progress', function(e){ console.log(e.percent); }); }; API file(file)

Wraps a File object:

var file = require('file'); file(input.files[0]); File#is(type)

Returns a boolean if the file's mime type matches type:

var file = require('file'); file(input.files[0]); file.is('image/*'); file.is('image/jpeg'); file.is('*/json'); File#toArrayBuffer(fn)

Convert to an ArrayBuffer and invoke fn(err, result), returns a Reader.

Convert to text and invoke fn(err, result), returns a Reader.

Convert to a data uri string and invoke fn(err, result), returns a Reader.
