Wim Pool presented on building an email client using Meteor. Meteor is a platform for building JavaScript apps that was first previewed in 2011 and officially released in 2014. It uses reactive programming to simplify development. Key Meteor components include Blaze for reactive UIs, Tracker for reactivity, DDP for data protocol, and Livequery for live database connections. Meteor aims to make development simple with a unified JavaScript language, data query language, and publish/subscribe model for client-server communication.
