YO CAM

README.md

instructions

1. deploy server.js somewhere (i just used heroku)
2. create an API yo account on http://developer.justyo.co/, set the callback URL to http://<server url>/yo
3. run client.js on your computer (make sure you've edited the socket.io URL)
4. send yo's to your API account

notes

this is very specific to my usecase: sending a photo of me from my webcam to a group chat i have with my friends on facebook. because facebook doesn't have a chat API for group chats, i use selenium to control a browser to upload stuff. it's ugly, but it works!

if you use this for your own craziness, you don't need any of the selenium/notifier stuff, just the socket.io stuff.

i used socket.io since it was super easy to set up, and very fast. it triggers pretty much instantly after the yo is sent, so that's cool. have fun!

client.js

var io = require('socket.io-client')('http://xxxxxxxxxxxx.herokuapp.com/');
var exec = require('child_process').exec;
var webdriver = require('selenium-webdriver');
var Notification = require('node-notifier');
var notifier = new Notification();

var driver = new webdriver.Builder().
    withCapabilities(webdriver.Capabilities.chrome()).
    build();

driver.get('https://m.facebook.com/messages/read/?tid=id.xxxxxxxxxxxxxxxxx'); // mobile fb loads a lot faster

driver.findElement(webdriver.By.css('[name=email]')).sendKeys('email');
driver.findElement(webdriver.By.css('[name=pass]')).sendKeys('password');
driver.findElement(webdriver.By.css('[name=pass]')).submit();

io.on('connect', function () {
    console.log('yocam: connected to socket.io');
});

// the code inside this is very specific to what i was doing, you don't need it
io.on('yo', function (username) {
    // http://iharder.sourceforge.net/current/macosx/imagesnap/
    exec('imagesnap -w 1', function (err) {
        notifier.notify({
            title: 'YOCAM',
            message: username + ' TOOK YO PICTURE'
        });
        console.log('yocam: ' + username + ' sent a yo');

        if (err) throw err;

        var msg;
        if (username === 'BRUGGIE') {
            msg = 'zach, you\'re using this to take a selfie, stop';
        } else {
            msg = 'hi ' + username + '! ';
        }
        driver.findElement(webdriver.By.css('textarea[name=body]')).sendKeys(msg);
        driver.findElement(webdriver.By.css('[type=file]')).sendKeys(process.cwd() + '/snapshot.jpg');

        // hecka unstable, sometimes it can't find the el and it crashes
        // i run the client with `forever` so it just restarts
        // i could actually catch the exception but nahh
        driver.wait(function () {
            return driver.isElementPresent(webdriver.By.css('.btnC[name=send]:not([disabled])')).then(function (element) {
                driver.findElement(webdriver.By.css('.btnC[name=send]')).click();
            });
        });
    });
});
