Almog Koren gave a presentation on Meteor, an open source platform for building web and mobile apps in JavaScript. Meteor allows for real-time updates, latency compensation, and hot code pushes. It uses a single programming language (JavaScript) and provides packages that handle tasks like live queries and synchronization. Businesses like Workpop have been built using Meteor due to its support for rapid prototyping. Meteor is growing in popularity, with over 150 meetup groups and 2000 community packages. Koren recommended resources like Meteor.com and Discover Meteor for learning how to develop apps with Meteor.

METEORJS

8. 238Presentation by Almog Koren  Apr 14, 2015
WHAT IS METEOR?
• Open source platform for building web and mobile apps in
JavaScript
• Built to power the next generation of apps
• Rich user interfaces
• Collaborative multi-user applications
• Cross-platform apps (web, IOS, Android)
• Fast development

9. 239Presentation by Almog Koren  Apr 14, 2015
HOW MODERN APPS LOOK & FEEL
• Focus on your app’s unique features instead of wrangling
network code, websocket, etc.
• Meteor’s Goal: Facebook-quality apps without Facebook’s
money

10. 2310Presentation by Almog Koren  Apr 14, 2015
OLD TOOLS DON’T WORK
• Modern apps serve data, not html
• Modern apps shouldn’t need a refresh button
• Rails, Django, PHP, ASP.net etc. are difficult to adapt to the new
model

11. 2311Presentation by Almog Koren  Apr 14, 2015
WHY?
PURE JAVASCRIPT
Write your entire app in pure
JavaScript.
LIVE PAGE UPDATES
Just write your templates.
DATA SYNCHRONIZATION
No more loading your data from
REST endpoints.

12. 2312Presentation by Almog Koren  Apr 14, 2015
WHY CONTINUED?
LATENCY
COMPENSATION
Immediate updates no waiting
for the server.
HOT CODE PUSHES
Update your app while users are
connected.
PRIVILEGED
ENVIRONMENT
Write all of your code in
JavaScript.

13. 2313Presentation by Almog Koren  Apr 14, 2015
WHY CONTINUED?
APPLICATION BUNDLES
One command to compile your
entire application into a tarball..
INTEROPERABILITY
You can connect anything to
Meteor.
SMART PACKAGES
Tempting, testing, or DOM
manipulation frameworks.
