## Node Registration Patterns

ComfyUI uses two main patterns for registering nodes:

### 1. Legacy Pattern (NODE_CLASS_MAPPINGS)

```python
NODE_CLASS_MAPPINGS = {
    "NodeName": NodeClass,
}
```

### 2. New Pattern (ComfyExtension + io.Schema)

```python
class MyNode(io.ComfyNode):
    @classmethod
    def define_schema(cls):
        return io.Schema(
            node_id="MyNodeName",
            category="category/subcategory",
            inputs=[...],
            outputs=[...]
        )

class MyExtension(ComfyExtension):
    async def get_node_list(self):
        return [MyNode]
```
