A reactive backend with TypeScript uses serverless functions for automatic data synchronization. Convex provides queries, mutations, and actions that instantly update data across all connected clients, enabling collaborative application features.

Implementing optimistic updates in a serverless backend involves applying local UI changes immediately while the backend mutation syncs in the background. Convex supports this pattern to ensure smooth user experiences without waiting for network round-trips.

Yes, you can manage file uploads and user authentication directly within a Convex backend. The platform provides built-in storage for file handling and supports Convex Auth to integrate secure user authentication into your reactive application.

Yes, Convex supports schema design for real-time data synchronization. You define your database schema in TypeScript, which allows the integrated database to instantly push synchronized data updates to all active clients.

The best way to create a collaborative document editing tool with instant updates is using a reactive backend. Convex enables real-time data synchronization, immediately propagating changes made by one user to all other active collaborators.
