index.html

<form class="mediaForm" enctype="multipart/form-data">
    <input name="file" type="file" class="media" />
    <input type="submit" name="submit" class="submit" />
</form>

main.js

web.js

// NodeJS server using expressJS

    var errors = new Array();
    
    fs.readFile(file.path, function (err, data) {
        if(err) throw err;

        var newPath = __dirname + "/uploads/" + file.name;

        fs.writeFile(newPath, data, function (err) {
            if(err) {
                throw err;
                errors.push(err);
