-## Road Map

-### What has been done
-
-- Migrate all code to TypeScript with minimal change modification to the original logic.
-- Bundle all code with Vite's rollup build.
-- Added a shim layer to be backward compatible with the existing extension system. <https://github.com/huchenlei/ComfyUI_frontend/pull/15>
-- Front-end dev server.
-- Zod schema for input validation on ComfyUI workflow.
-- Make litegraph a npm dependency. <https://github.com/Comfy-Org/ComfyUI_frontend/pull/89>
-- Introduce Vue to start managing part of the UI.
-- Easy install and version management (<https://github.com/comfyanonymous/ComfyUI/pull/3897>).
-- Better node management. Sherlock <https://github.com/Nuked88/ComfyUI-N-Sidebar>.
-- Replace the existing ComfyUI front-end implementation. <https://github.com/comfyanonymous/ComfyUI/pull/4379>
-
-
-### What to be done
-
-- Remove `@ts-ignore`s.
-- Turn on `strict` on `tsconfig.json`.
-- Add more widget types for node developers.
-- LLM streaming node.
-- Linear mode (Similar to InvokeAI's linear mode).
-- Keybinding settings management. Register keybindings API for custom nodes.
