Which programming languages are supported by this skill?

The skill provides comprehensive templates and implementation logic for both TypeScript (using Express or Fastify) and Python (using Flask).

Can I deploy the backend using Docker?

Yes, the skill includes standardized Dockerfile and docker-compose.yml templates for easy containerization and deployment of your plugin's backend.

Does it include security best practices?

Yes, it provides guidance on CORS configuration, environment variable management, input validation, and secure communication patterns between the plugin and server.

Why would an Obsidian plugin need a backend server?

A backend is necessary for tasks that cannot run in a browser environment, such as utilizing Python-based machine learning libraries, performing heavy CPU-intensive computations, or accessing system-level Node.js packages.

How does the plugin communicate with the backend?

The skill generates a BackendService class for the Obsidian plugin that handles HTTP requests, includes automated health checks, and manages request timeouts.

API Development

Develops and manages robust backend servers for Obsidian plugins requiring server-side processing, machine learning, or complex computations.

About

Obsidian Plugin Backend Builder is a specialized Claude Code skill designed to bridge the gap between Obsidian's browser-based environment and powerful server-side capabilities. It provides standardized templates and implementation patterns for creating Node.js (Express/Fastify) or Python (Flask) backends, enabling plugins to leverage heavy computation, machine learning libraries, and database operations that are not natively possible within the Obsidian desktop or mobile application context.

Key Features

Standardized directory structures for seamless plugin-to-backend integration
1 GitHub stars
Robust health check and error handling service implementations for the plugin side
Docker deployment configurations for containerized server environments
Multi-language server templates including TypeScript/Express, Fastify, and Python/Flask
Pre-built patterns for file processing, batch operations, and streaming responses

Use Cases

Running heavy computational tasks that would otherwise freeze the Obsidian UI
Integrating local LLMs, embeddings, or NLP libraries for advanced note analysis
Executing Node.js or Python packages that require a full system environment rather than a browser
