Connect to a PULSAR broker instead of MQTT

General
1

Hello,

I'm new to this forum. I manipulate a little Node-red for my home automation.
For my TUYA components, I will need to connect to a PULSAR broker instead of MQTT.
I've seen MQTT nodes but not Pulsar. Does anyone know how to use pulsar with Node-red?

Thanks

I would start here on the documentation from PULSAR
https://pulsar.apache.org/docs/3.1.x/client-libraries-node/
It looks like they have a nodeJS client on npm.
https://www.npmjs.com/package/pulsar-client

You may be able to add it to the function node.

I assume that you already have access to a PULSAR server? I note that, in typical (and annoying) Apache fashion, it requires Java and does not talk about memory/cpu resource constraints. If you need to run your own server, be warned that it might push a limited device such as a 1GB RAM Pi over the edge.

Thank you 2

The purpose of my request is not to set up a PULSAR server. I'm just looking for a node to connect to a PULSAR server on the WAN. TUYA provides the server.

@meeki007: I must admit I'm not sure of my programming skills. But I'll give it a try.

If I understand correctly, node.js code is Javascript if I use it more or less raw I should be able to use it in node Function Node-red. Is that it?

You use the npm client module @meeki007 suggested in a function node.

Here is an article that might help: Use any npm module in Node-RED • FlowFuse

Thank you very much,

I'll look into it. I just hope that my installation with HomeAssistant won't give me any trouble.

Thanks again

Hello and thank you

I was able to look at your posts I'll have to dig into nodejs node-red interaction a bit later.

In the meantime Tuya got back to me about using Pulsar and given the prices I'm going to go back to something more basic.

Thanks again
