To build a reactive backend for real-time data synchronization, you can use Convex serverless functions and its real-time database, which automatically pushes data updates instantly to all connected clients.

You write serverless backend functions for database mutations by using the Convex SDK to define TypeScript queries and mutations, automatically handling reactive data synchronization across your application.

Optimistic updates in a real-time collaborative application provide instant UI feedback during data mutations by immediately updating the client interface while the reactive backend synchronizes the actual database state.

Yes, you can use TypeScript to define database schemas, queries, mutations, and actions in a serverless backend by utilizing the Convex SDK for structured, type-safe reactive application development.

The best way to handle file uploads with a serverless backend is using Convex storage, which integrates directly with your reactive database schemas and TypeScript mutations to manage uploaded files.

Yes, a reactive backend supports building collaborative document editors by leveraging real-time data synchronization, ensuring changes made by one user are immediately visible to all other collaborators.
