Craft Collaborative Apps with Realm (JP 🇯🇵 + EN 🇺🇸)

This talk will introduce into the open-source Realm Mobile Database and show how the Realm Mobile Platform completes it by server-side components. This allows you to treat synchronization and network as implementation detail in your technology stack. Features like live collaboration, which would have been a major undertaking, become all of the sudden easily available to every developer. This talk shows you how you can craft reactive apps with a database which takes care of the rest.
