How to send an event to a node

[xakslim]

Hello. I created custom nodes with a certain number of inputs and outputs. node fields are displayed in a separate dialog box. everything works here. at the moment I need to carry out the necessary checks. for example, I should not have unconnected nodes. and it is necessary to highlight this node and display an error under it. How can I send an event to a node? using vue2? vue-render-plugin, area-plugin

do you need to display an error inside the node block or outside? In the first case definitely you need a custom node

needed outside. The custom element already has a class and an error text. I get a list of invalid nodes, but somehow I need to pass either an event or this class to them

but somehow I need to pass either an event or this class to them

const node = editor.nodes.find(node => ... // find particular node
node.data /// put error identifier or whatever into this object
node.update()

Respectively, your custom node should retrieve error info from node.data
