lmstudio-extensions

A starter monorepo for building LM Studio extensions.

Recommended stack

• Language: TypeScript
• Package layout: Bun workspaces
• Repo workflow: jj with Git compatibility

Why TypeScript?

For an LM Studio extension monorepo, TypeScript is the safest default because it gives you:

• Shared types across packages
• Easier refactors as the repo grows
• Good support in the Node.js ecosystem
• Cleaner boundaries between extensions and shared utilities

If you later need model helpers, data processing, or automation scripts, you can add a Python package alongside the TypeScript packages.

Layout

• apps/example-extension — a starter extension package
• packages/shared — shared utilities used by multiple packages
• tsconfig.base.json — shared compiler configuration
• tsconfig.json — root project references

Commands

After installing dependencies:

• bun install — install dependencies
• bun run build — build all packages
• bun run clean — remove build output

Notes about jj

This repo was initialized with jj in colocated mode, so normal Git-compatible workflows still work.

A simple day-to-day flow is:

• Make your changes
• Check status
• Commit with jj
• Push to the GitHub remote

If you want, I can next turn this starter into a real LM Studio extension package structure with a manifest, API wiring, and a proper dev/build pipeline.
