Realm Web SDK
The Realm Web SDK lets browser-based applications access data stored in Atlas and interact with App Services services like Functions and authentication. The Web SDK supports both JavaScript and TypeScript.
Web apps built with Realm use the Atlas GraphQL API or query data stored in Atlas directly from the browser. Unlike the other Realm SDKs, the Web SDK does not support creating a local database or using Atlas Device Sync.
