Plugin Frameworks
Build extensible applications where plugins run in isolated contexts. Each plugin registers its commands, and the host can call them by ID. Plugins can be loaded/unloaded dynamically without affecting the main application.
Use Cases
cmd-ipc is designed for applications that need reliable, type-safe communication across process boundaries.
Examples
Section titled “Examples” Web Workers Offload heavy computation to background threads while keeping the main thread responsive. Perfect for image processing, data analysis, and CPU-intensive tasks.
Electron Type-safe IPC between main and renderer processes. No more manual message type definitions or serialization boilerplate.
Cloudflare Workers Build HTTP APIs with automatic schema discovery. Clients generate types from your server's command schemas.
MCP Agent Expose commands as tools for AI agents via the Model Context Protocol. Claude, GPT, and other models can discover and call your commands.
Other Use Cases
Section titled “Other Use Cases”Unit Testing
Decouple services without dependency injection. Commands provide natural boundaries for mocking—swap out command handlers in tests for predictable, isolated unit tests without complex DI containers.
Microservices
Share types across services in a monorepo. The HTTPChannel works well for backend-for-frontend patterns, API gateways, and edge functions calling origin servers.
Node.js Workers
Use worker_threads with the same API as Web Workers. The MessagePortChannel works identically in both environments, so code is portable between browser and Node.js.
