Development

Tech Stack

• Vue 3 with TypeScript
• Pinia for state management
• PrimeVue with TailwindCSS for UI
• Litegraph for node editor
• zod for schema validation

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

Unit 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.

Component Test

Component test verifies Vue components in src/components/.

• npm run test:component to execute all component tests.

Playwright Test

Playwright test verifies the whole app. See https://github.com/Comfy-Org/ComfyUI_frontend/blob/main/browser_tests/README.md for details.

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.

Test litegraph changes

• Run npm link in the local litegraph repo.
• Run npm link @comfyorg/litegraph in this repo.

This will replace the litegraph package in this repo with the local litegraph repo.

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.

Publish release to ComfyUI main repo

Run following command to publish a release to ComfyUI main repo. The script will create a new branch and do a commit to web/ folder by checkout dist.zip from GitHub release.

• python scripts/main_repo_release.py <path_to_comfyui_main_repo> <version>
