At WordCamp Norway I presented about why Javascript matters when developing for WordPress. The amount of Javascript grows and it's time that developers look more into Javascript.

The focus is around the example I build for WordSesh to show what you can do with Javascript and Node.js

Why Javascript matters WordCamp Norway - 2014

Who I am? • Marko Heijnen - @markoheijnen • Working at 1&1 Internet as their WordPress specialist • WordPress core contributor • GlotPress core developer - @GlotPress • Co-author of WP_Image_Editor

Agenda • Why, we as PHP developers, should focus more on the Javascript side • Showing features of Javascript you didn’t know • Ending with an awesome example

WordPress has grown • PHP - 69.1 % • Javascript - 18.4 % • CSS 12.5 %

Current libraries we use • • • • jQuery Backbone.js MediaElement.js TinyMCE ! ! • • • • jQuery UI Underscore.js Plupload zxcvbn

History • WordPress 2.2 starts using jQuery • 3.5 using Backbone/Underscore for the media dialog • 3.6 • MediaElements for audio/video control • Heartbeat API • Revisions started to use Backbone

Future • 3.9 will add playlists for audio & video • TinyMCE 4 • Image editor UI

The things you want to do often, now requires understanding of Javascript

Opening a new media dialog // Create the media frame. image_frame = wp.media.frames.formatImage = wp.media({ // Set the title of the modal. title: $el.data('choose'), // Tell the modal to show only images. library: { type: 'image' }, // Customize the submit button. button: { // Set the text of the button. text: $el.data('update') } }); image_frame.open();

Cool stuff you
 have in Javascript

getUserMedia / WebRTC for live streaming

Using Javascript to build almost native apps


Node.js • Javascript platform • Uses an event-driven, non-blocking I/O model • Lightweight and efficient • Ideal for real time application • http://nodejs.org/

Running a webserver with Node.js

var http = require('http'); http.createServer(function (req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); res.end('Hello Worldn'); }).listen(1337, '');

The awesome example WordSesh needs NodeJS

WordSesh - Problems • Needs to be refreshed every hour • Has 15 minutes of silence • Results in accidentally playing the previous session

WordSesh - Idea • NodeJS lets you push new sessions • When the session is over, it will be removed • Be able to use YouTube files as wait music • Create a hangout through WordPress

Control panel - two channels
