13. The web in 2014
• Rich applications
– Real time updates
– Single page
• Short development cycles

18. Seven Principles of Meteor
Data on the Wire. Send data, not HTML, over the network. Let the client
decide how to render it.
One Language. Write both the client and the server parts of your
interface in JavaScript.
Database Everywhere. Use the same transparent API to access your
database from the client or the server.
Latency Compensation. On the client, use prefetching and model
simulation to make it look like you have a zero-latency connection to the
database.

19. Seven Principles of Meteor
Full Stack Reactivity. Make realtime the default. All layers, from
database to template, should make an event-driven interface available.
Embrace the Ecosystem. Meteor is open source and integrates, rather
than replaces, existing open source tools and frameworks.
Simplicity Equals Productivity. The best way to make something
seem simple is to have it actually be simple. Accomplish this through clean,
classically beautiful APIs.

20. Getting Started
Install Node and Meteor
(Mac / Linux) curl https://install.meteor.com | /bin/sh
(Windows) http://win.meteor.com/

21. 1. Create an example
2. Run the app

22. File Structure
• /server - runs on the server
• /client - runs on the client
• /, /common - runs on both
• static assets (fonts, images, etc.) go
in /public
