var fs = require('fs'),
    http = require('http'),
    express = require('express'),
    NodeWebcam = require("node-webcam");

var opts = {

    width: 1280,
    height: 720,
    delay: 0,
    quality: 100,
    output: "jpeg",
    verbose: false

}

var Webcam = NodeWebcam.create(opts);

app = express();

var server = http.createServer(app);
app.use(express.static('app'));

app.get('/', function(req, res) {
    res.writeHead(200, {
        'Content-Type': 'multipart/x-mixed-replace; boundary=myboundary'
    });

    var capture = function() {
        Webcam.capture("my_picture");
        fs.readFile('./' + 'my_picture.jpg', function(err, content) {

            if (err) {
                console.log(err);
                return;
            }

            res.write("--myboundary\r\n");
            res.write("Content-Type: image/jpeg\r\n");
            res.write("\r\n");
            res.write(content, 'binary');
            res.write("\r\n");

        });
        setTimeout(capture, 100);
    };

    capture();

});

var port = process.env.PORT || 8080;

server.listen(port, function() {
    console.log('Listening on ' + port);
});
