npm installed packages do not show up in Manage Palette > Install

[Andrej Falout]

Hi all,

I have two nodes that I installed with npm:

npm install -g mmcontrol
npm install -g flick-electric-api

Sources:

https://github.com/lennyby93/node-mmcontrol
https://github.com/madleech/FlickElectricApi

... that do not show in the Node-red Manage Palette > Install

running node-red -v does not show any issues

I installed pushbullet using same procedure, and it shows in Manage Palette without any issues.

Being a complete beginner in both npm packaging and node-red, I dont really know where to find what exactly the packages need to look like. Tried to replicate some alternative installation methods I found in this group (such as "npm install /tmp/my-node") but nothing worked.

Is there a way to debug why node-red "see" some npm installed packages, but not others?

Any suggestion very much appreciated.

Cheers,
Andrej

Hi,

the palette manager in Node-RED only knows about npm modules that contain Node-RED nodes. These are the ones that are indexed on https://flows.nodered.org. It is not a generic npm install tool.

Oh-uh... thanks Nick!

Maybe someone should mention that fact in Node-red documentation... explicitly.

So node-red has special rules for npr packages? Where can I find these rules?

And can anyone possibly take a look at these GIT repositories to see what is missing?

https://github.com/lennyby93/node-mmcontrol
https://github.com/madleech/FlickElectricApi

My intention is to create a simple workflow that would control my heat pump/aircon (node-mmcontrol) according to the current electricity price (FlickElectricApi)

Much appreciated!

Cheers,
Andrej

Hi Andrej,

The modules you've linked to are general node.js modules.

You'd need to create Node-RED nodes that wrap them: https://nodered.org/docs/creating-nodes/

Thanks Nick.

I wonder if you are aware of some Node-RED nodes that are comparable in function, that I can use as a template / starting point?

- First one is a simple web service that takes username/password as an input, and returns current cost of electricity

- Second one is a device control that takes username/password, and sets carious functions of the device (power state, operation mode, speed of fans, temperature etc), and can read current states of device (power mode, standby mode, operation mode, fan speed, room temperature and target temperature)

Is anyone aware of similar working nodes?

Alternatively - is there a way to invoke general node.js modules from Node-RED?


Thanks,
Andrej
