Atlas Device SDK for C++

Install the C++ SDK

Use Swift Package Manager or Cmake to Install the C++ SDK in your project.

Include the header in the translation unit where you want to use it to get started.

Define an Object Schema

Use C++ to idiomatically define an object type.

Open a Database

The SDK's database - Realm - stores objects in files on your device. Configure and open a database to get started reading and writing data.

Read and Write Data

Create, read, update, and delete objects from the database. Filter data using the SDK's query engine.

React to Changes

Live objects mean that your data is always up-to-date. You can register a notification handler to watch for changes and perform some logic, such as updating your UI.

Connect to an Atlas App Services App

Configure Device Sync in an App Services App. Define data access rules. Use Development Mode to infer your schema from your C++ data model.

Then, connect to the backend from your client.

Authenticate a User

Use one of our authentication providers to authenticate a user. App Services provides access to popular authentication providers, such as Apple, Google, or Facebook. Use our built-in email/password provider to manage users without a third-party, or use custom JWT authentication to integrate with other authentication providers. Anonymous authentication provides access without requiring a login or persisting user data.

Open a Synced Database

Configure and open a synced database. Subscribe to a query to determine what data the synced database can read and write.

Read and Write Synced Data

The APIs to read and write data are the same whether you're using a synced or non-synced database. Data that you read and write to the device is automatically kept in sync with your Atlas cluster and other clients. Apps keep working offline and deterministically sync changes whenever a network connection is available.
