I'm loading the [day.js module](https://day.js.org/docs/en/installation/installation) in the function node setup tab, and it works fine for basic date/time functions, however for more advanced functions, it requires additional plugins to be loaded as per the readme - [Loading plugin in NodeJS · Day.js](https://day.js.org/docs/en/plugin/loading-into-nodejs)

![plugin](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/8/7/87a953643cc0cca405a2b3e3718d3b5c1ff8507e.jpeg)

The dayjs plugins have been installed by default when dayjs is added, and are at `/home/pi/.node-red/externalModules/node_modules/dayjs/plugin` but adding the plugin as per the screenshot above results in a node-RED crash.  
Can these supplementary modules also be added in the function node setup by adding the path somehow?

No, I don't think the externalModules stuff will work with that. It isn't a scenario that has been considered.

Ah well, I'll look for a different solution instead of dayjs.  
Thanks
