Node developers API

v1.2.4: Extension API to register custom sidebar tab

Extensions now can call the following API to register a sidebar tab.

  app.extensionManager.registerSidebarTab({
    id: "search",
    icon: "pi pi-search",
    title: "search",
    tooltip: "search",
    type: "custom",
    render: (el) => {
      el.innerHTML = "<div>Custom search tab</div>";
    },
  });

The list of supported icons can be found here: https://primevue.org/icons/#list

We will support custom icons later.

  })

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.

What to be done

• Replace the existing ComfyUI front-end impl
• Remove @ts-ignores.
• 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.
• New extensions API for adding UI-related features.

Development

Git pre-commit hooks

Run npm run prepare to install Git pre-commit hooks. Currently, the pre-commit hook is used to auto-format code on commit.

Dev Server

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

• git clone https://github.com/comfyanonymous/ComfyUI_examples.git to tests-ui/ComfyUI_examples or the EXAMPLE_REPO_PATH location specified in .env
• npm i to install all dependencies
• npm run test:generate to fetch tests-ui/data/object_info.json
• npm run test:generate:examples to extract the example workflows
• npm run test to execute all unit tests.

LiteGraph

This repo is using litegraph package hosted on https://github.com/Comfy-Org/litegraph.js. Any changes to litegraph should be submitted in that repo instead.

Deploy

• Option 1: Set DEPLOY_COMFYUI_DIR in .env and run npm run deploy.
• Option 2: Copy everything under dist/ to ComfyUI/web/ in your ComfyUI checkout manually.
