ComfyUI Node Builder provides a powerful, type-safe framework for creating custom nodes in ComfyUI using Rust.

Built with performance in mind, this framework offers faster execution times and a more streamlined development experience compared to traditional Python-based node development.

Basic Node Example

use comfyui_plugin::prelude::*;

#[derive(NodeInput)]
pub struct Input {
    a: usize,
    b: usize,
}

#[derive(NodeOutput)]
pub struct Output {
    sum: usize,
}

#[node(
    category = "MyNode / Math",
    description = "Sums a + b inputs."
)]
pub struct Sum;

impl Node for Sum {
    type In = Input;
    type Out = Output;
    type Error = Box<dyn Error + Send + Sync>;

    fn execute(&self, input: Self::In) -> Result<Self::Out, Self::Error> {
        Ok(Output {
            sum: input.a + input.b
        })
    }
}

boostrap!(api_version: "latest");
