• 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.
