# ComfyUI v2 Frontend Extension API
The v2 extension API is the published npm package `@comfyorg/extension-api`. It
replaces the legacy `app.registerExtension()` / `nodeType.prototype` monkey-patching
model with a typed, tree-shakeable, import-based API.
> If you are converting an existing v1 extension, read
> [`references/migrate-v1-to-v2.md`](references/migrate-v1-to-v2.md) for a
> pattern-by-pattern mapping.
## Mental model
| v1 (legacy) | v2 (`@comfyorg/extension-api`) |
