comfyui how to install custom nodes

Integrating custom nodes into ComfyUI projects involves creating classes extending the Node class and implementing the init() and render() methods. These classes can be added to the ComfyUI configuration and used like built-in nodes. Detailed steps a

Steps for Installing Custom Nodes

The steps for installing custom nodes in ComfyUI are as follows:

1. Create a new project.
2. Add the ComfyUI library to your project.
3. Create a new class that extends the Node class.
4. Implement the init() and render() methods in your custom node class.
5. Add your custom node class to the ComfyUI configuration.
6. Build and run your project.

1. Create a new project

First, you need to create a new project. You can do this by opening your favorite development environment and creating a new project.

2. Add the ComfyUI library to your project

Next, you need to add the ComfyUI library to your project. You can do this by adding the following lines to your project's package.json file:

<code>{
  ...
  "dependencies": {
    "comfyui": "^1.0.0"
  }
  ...
}</code>

3. Create a new class that extends the Node class

Next, you need to create a new class that extends the Node class. This class will define the custom behavior of your node.

<code class="javascript">export class MyNode extends Node {
  constructor(props) {
    super(props);
  }

  init() {
    // Your initialization code goes here.
  }

  render() {
    // Your rendering code goes here.
  }
}</code>

4. Implement the init() and render() methods in your custom node class

The init() method is called when the node is first created. This is where you should perform any initialization logic, such as setting up event listeners or fetching data from a server.

The render() method is called when the node is rendered. This is where you should return the HTML for your node.

5. Add your custom node class to the ComfyUI configuration

Next, you need to add your custom node class to the ComfyUI configuration. You can do this by adding the following line to your project's comfyui.config.js file:

<code class="javascript">// comfyui.config.js
import { MyNode } from "./MyNode";

export default {
  ...
  nodes: {
    myNode: MyNode
  }
  ...
};</code>

6. Build and run your project

Finally, you can build and run your project. To do this, run the following command:

<code class="bash">npm run build</code>

Once your project is built, you can run it by running the following command:

<code class="bash">npm start</code>

How can I integrate custom nodes into my comfyui project?

To integrate custom nodes into your ComfyUI project, you can follow the steps outlined in the previous section. Once you have created your custom node class and added it to the ComfyUI configuration, you can use it in your project like any other built-in node.

For example, the following code creates a new instance of the MyNode class and adds it to the ComfyUI canvas:

<code class="javascript">const myNode = new MyNode({
  x: 100,
  y: 100
});

canvas.addNode(myNode);</code>

Where can I find documentation or tutorials on installing custom nodes in comfyui?
