Out of the box, gun makes data synchronization effortless, handling offline changes and gruesome merge conflicts seamlessly. Every time a client recieves data, gun makes a local copy for speed and efficiency, meaning that your most crucial data is backed up on every peer that uses it, making loss of important information nearly impossible. With gun's graph database architecture, every form of data can be expressed, allowing for emergent, flexible, and powerful data structures in your application. While functionality can be customized, gun comes with defaults that make getting started just about as simple it gets.
