A reactive , data-synchronizing,
Latency-compensating, time-saving platform.
for building fast, interactive web apps

A full-stack, open source platform for building web and mobile apps in JavaScript
Fast and fun development
What is Meteor…
What's different ?
Traditional App• Browser makes a request to server,
http://example.com/items.html
•server responds with html code <html>
<p>Item 1</p>
<p>Item 2</p>
</html>
What's different ?Meteor App
•Browser subscribes (to items) from Server
Subscribe to items
•Also browser knows when new items added on
server.•Response is :<p>Item 1</p><p>Item 2</p>
What's different ?
Meteor AppLatency Compensation
When adding new item by browser, •local storage updated first, •then send to server for update.•Server then updates client “Everything
went OK” .Hence Reactive.

Browser Mobile
Refresh button Live updates
Individual sessions Multiuser collaboration
Links and forms Native-style GUI
Updates without refreshing the browser
Real-time collaboration
Result: Complex stack
HTML Templates App Logic
Reactive UI update system
Native mobile container
Speculative client-side updates
Client-side data store
Custom data sync protocol
Realtime database monitoring
