Backend servers for Obsidian plugins handle server-side processing that the browser cannot run. Use the provided starter templates in Express+TypeScript or Python Flask to scaffold a server with health checks and API endpoints, then deploy it alongside your plugin to process heavy computation, ML tasks, or database operations.

Yes. This Skill provides starter templates for both Express with TypeScript and Python Flask backends designed specifically for Obsidian plugin integration, letting you choose the framework and language that fit your tech stack.

Backend servers handle ML inference, embeddings, long-running computations, database operations, and other heavy processing unavailable in the browser. The plugin calls your backend API and receives results, keeping the client responsive.

Deploy backend servers using the included deployment scripts configured for your chosen framework. The templates include health checks and a '/health' endpoint to verify the server is running before your plugin makes API calls.

The starter templates include sample routes like '/api/process' and health endpoints out of the box. Extend them with your own routes and business logic, with configuration options and testing patterns already in place.

Plugins run in the browser and face resource and capability limits; backends run on your infrastructure with full database access, CPU, and memory. Backend servers let you offload computation-heavy or data-intensive work while the plugin handles UI and coordination.
