I come up with another weired question. Ages ago I started to develop a node. With the time, more and more parameters were added and now (with a major version bump) I'm going to move these parameters to a configSet. The scenario I'm considering only deals with users who updates the node. They proba…

Yep you have to leave the property in default and remove value to not create one So: default: { toggleTopic: {} // may contains validator and label }

[image] danube: I see no possibility to automatically create a new configSet with the prior settings (please oh please correct me if I'm wrong). Why not? You have the old data and all you need is to transfer to the new config and set a flag to say you've done it - and probably then blank the …

[image] TotallyInformation: Why not? You have the old data and all you need is to transfer to the new config and set a flag to say you've done it - and probably then blank the old data. That was EXACTLY my idea :star_struck: But how to generate a new configSet automatically? :thinking:

Oh damn, of course, that's it... :face_with_peeking_eye:

[image] danube: But how to generate a new configSet automatically? It is not that hard. You would check whether your new fields contained anything and if not, run a function to copy from the old to the new. The complexity is in the time period between installing the new version with the new …

That's valuable information, many thanks. Basically, all the things around work already. I'm still unsure about one thing: The previous version of the node had only some plain parameters. No configSet. The new version has that. But afaik, the user must first create a configuration node to be able to…

[image] danube: the user must first create a configuration node Ah, yes. That is indeed a bit of an issue. I've fallen foul of this myself in UIBUILDER. It should be possible to automate the creation of a config node? I've never worked it out though I'm afraid and I can't immediately find an…

[image] TotallyInformation: It should be possible to automate the creation of a config node? Yes, I have an example from Victron: victronenergy/node-red-contrib-victron/blob/ac5e383b727a13d7f613cb02c183f5b205408c1b/src/nodes/victron-nodes.html#L357-L374 onadd:…

Thanks for that. Maybe I'll finally get round to re-factoring UIBUILDER to use a config node! :wink:

[image] GogoVega: Yes, I have an example from Victron: That's a sweet reference and I'd like to discuss it with you. victron seems to deal with strings as the id, am I getting this wrong? It then creates the object victronClientNode and writes id: "victron-client-id". But isn't the ID always…

[image] danube: But isn't the ID always some 16 digit random hex thing? It's not an error, it's a choice to explicitly recognize this node. Victron systems have mdns (discovery) and therefore the config node does not need configurations to be deployed. [image] danube: What to write in t…

I believe this is an oversight, plugins and nodes have an onadd property.

This property is old and was internally used for the feature: Allow node name to be auto-generated when added by knolleary · Pull Request #3478 · node-red/node-red · GitHub
