ComfyUI_frontend

Front-end of ComfyUI modernized. This repo is fully compatible with the existing extension system.

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.

What to be done

• Replace the existing ComfyUI front-end impl.
• Turn on strict on tsconfig.json.
• Introduce react to start managing part of the UI.
• Introduce a UI library to add more widget types for node developers.
• LLM streaming node.
• Linear mode (Similar to InvokeAI's linear mode).
• Invoke AI canvas.
• Better node search. Sherlock https://github.com/Nuked88/ComfyUI-N-Sidebar.
• Keybinding settings management. Register keybindings API for custom nodes.
• New extensions API for adding UI-related features.

Development

Note: The dev server will NOT load any extension from the ComfyUI server. Only core extensions will be loaded.

• Run npm install to install the necessary packages
• Start local ComfyUI backend at localhost:8188
• Run npm run dev to start the dev server

Test

• npm i to install all dependencies
• npm run test:generate to fetch tests-ui/data/object_info.json
• npm run test to execute all unit tests.

Deploy

Copy everything under dist/ to ComfyUI/web/ in your ComfyUI checkout.

Breaking changes

• api.api_url now adds a prefix api/ to every url going through the method. If the custom node registers a new api endpoint but does not offer the api/ prefixed alt endpoint, it will have issue. Luckily there aren't many extensions that do that. We can perform an audit before launching to resolve this issue.
