I am developing a config node X that needs to find a list of other nodes that uses it. This list is needed during config node initialization.

Any convenient way to do it?

Thanks

In the editor or in the runtime?

Not sure if this is the _correct_ way, but it works.

```javascript
const configId = this.id;

RED.nodes.eachNode((n) => {
  if (n.config === configId) {
    // Node `n` is using this config node
  }
});

```
