Using only one node

[sercancetin]

Hello, in node red tabs only one node will be used and the other node created will remain non-functional. For example, let there be a node named node a in the system, and the other added node a should not be used. what is the way to do this? So I don't want to have n nodes named a. Or let me ask the question this way. How do I know how many nodes have been created?

Hi,
Could you be clearer

You can disable a node by going to Manage Palette - once disabled, this node will no longer appear in the left bar.

How do I know how many x nodes have been created when coding nodes?

with counter incremented by RED.nodes.eachNode

[GogoVega]

Are you developing a node or is this a question related to default nodes? You added the function-node tag.

I think I added the wrong place. Yes, I'm creating a node.

So I don't want to have n nodes named a

Do you want each node to have a different name?

How can I avoid duplicate configuration node names?

Hi, I'm not sure I understood everything. The node name is purely visual and should not be used to identify a node in the code. This is the job of the id. It's possible to increment but only if you have developed the node. Otherwise you have to add an "nodes:add" event which when you add this node, updates the name by modifying the node properties. RED.events.on("nodes:add", (node) => { // Skip if not your node if (node.type !== "your-type") return; // check if name exist with // RE…

and the other added node a should not be used

Why would your users not use the node in the flow?
If you are using a Node as some sort of Configuration, then you need to define a configuration Node.

If a node in the flow is not designed for users to interact with - you really need to be using Config Nodes.

As mentioned by @GogoVega its not really clear what you are trying to achieve.
If you want to know if a node is not being used - Simply don't try and engineer it, its for the user to manage their estate.
