Overview

A suite of custom nodes for ComfyUI aimed at enhancing user experience with more interactive and visually engaging widgets.

Whether you're after quality-of-life improvements or specific functionalities, LF Nodes has you covered. The nodes are designed to be user-friendly and intuitive, making them accessible to users of all skill levels.

Most UI elements used by the frontend belong to the LF Widgets webcomponents library, a modern collection of modular and customizable webcomponents built on Stencil.js specifically to integrate with LF Nodes.

What kind of nodes does it offer?

That's a tough one—the nodes span quite a few categories. Here's a quick breakdown:

• Analytics nodes: Visualize and track data, like checkpoint/LoRA usage or image histograms.
• Configuration nodes: Manage CivitAI metadata, and control the suite via the Control Panel.
• Image manipulation nodes: Tools to manipulate images, such as filter and resize nodes.
• IO Operations nodes: Load and save files to/from the file system.
• JSON nodes: Tools to manipulate and display JSON data.
• LLM nodes: Interface with locally running LLMs, like the Messenger node, which also manages characters.
• Logic nodes: Control flow using simple switches.
• Primitive nodes: Work with primitive data types, offering features like history.
• Seed generation nodes: Generate seeds for complex workflows.
• Selector nodes: Resource selection widgets with metadata display for models.

Notes

The LLM nodes were tested with Koboldcpp, but any Open AI-compatible endpoint that does not require authentication/an API key should work. The model used in the workflows samples is UCLA-AGI/Llama-3-Instruct-8B-SPPO-Iter3 with ChaoticNeutrals/LLaVA-Llama-3-8B-mmproj-Updated.

pip install -r requirements.txt

This will install all the required dependencies for the Python backend.

To build the frontend, you will need to have Node.js and Yarn installed, then run the command

yarn setup

This command will install all the dependencies. Note that the repository includes the compiled frontend sources, so you can skip this step if you don't plan to modify the frontend.

yarn build

This command will compile all the frontend sources and generate/refresh the actual web directory.
