Realm is now Atlas Device SDK – Learn More
Explore engineering and expert-provided example projects to learn best practices and common development patterns for the Atlas Device SDKs, Atlas Device Sync, and Realm database.
Core Projects
Learn about the core features of the Atlas Device SDKs with Atlas Device Sync and Realm database.
Project Name | Description | Source Code for Available SDKs |
|---|---|---|
Template Apps | A todo list mobile app that syncs data with App Services using Device Sync. See
the App Services Getting Started page for more information
and detailed tutorials. | |
Connection State Change & Error Handling | Learn best practices around handling Sync errors and client reset strategies. | |
Offline Support and Realm Access | Log in a Device Sync user, open a synced realm, and perform local-first reads and writes, all while offline. | |
Split Data into Multiple Realms | Build a Netflix-like app for browsing movies from
MongoDB's Mflix sample dataset.
Use multiple realms to allow registered users to sync and manage movies in their own private list. |
