Basic data handling

Basic Python functions for manipulating data that every programmer is used to.

These nodes are very lightweight and require no additional dependencies.

Note

This projected is in early development—do not use it in production, yet!

Quickstart

1. Install ComfyUI.
2. Install ComfyUI-Manager
3. Look up this extension in ComfyUI-Manager. If you are installing manually, clone this repository under ComfyUI/custom_nodes.
4. Restart ComfyUI.

Tests

This repo contains unit tests written in Pytest in the tests/ directory. It is recommended to unit test your custom node.

• build-pipeline.yml will run pytest and linter on any open PRs
• validate.yml will run node-diff to check for breaking changes
