I use the node node-red-contrib-sun-position to have data of sun and moon position but I would like not use this node but an http request ....

How can I sniff the http request sent by the node node-red-contrib-sun-position?

I don't think it does send a request. I think it just calculates it using [suncalc3 - npm](https://www.npmjs.com/package/suncalc3)

Here is an example of how to use [suncalc3](https://www.npmjs.com/package/suncalc3) in a function node. You add the module in the function nodes setup tab.

```auto
[{"id":"c15cbedc83d28648","type":"inject","z":"d1395164b4eec73e","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"{}","payloadType":"json","x":235.9541015625,"y":4859.02734375,"wires":[["3c3dfdd83b03e76b"]]},{"id":"3c3dfdd83b03e76b","type":"function","z":"d1395164b4eec73e","name":"function 157","func":"const lat = 50.8015;\nconst lon = 0.3170;\nconst dateValue = new Date();\nmsg.payload.moon = suncalc.getMoonPosition(dateValue, lat, lon)\nmsg.payload.sun = suncalc.getPosition(dateValue, lat, lon)\nreturn msg;","outputs":1,"timeout":0,"noerr":0,"initialize":"","finalize":"","libs":[{"var":"suncalc","module":"suncalc3"}],"x":425.9541015625,"y":4859.02734375,"wires":[["7229b6af4a0552b4"]]},{"id":"7229b6af4a0552b4","type":"debug","z":"d1395164b4eec73e","name":"debug 429","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":450,"y":4780,"wires":[]}]

```

p.s could you also change the title to `how to get sun and moon positions` or similar, as the title does not help others search for what this topic is about.
