I was tempted to poke around the Developers section of ArcGIS, in the hopes of perhaps fingaling my way to a widget that behaved the way I wanted it to.
The requirements included your own installation of the ExB Developer Edition ~for which there is a handy video that purports to 'walk the viewer through the installation steps.' There's a bit of a gap in the instructions 37 seconds in.
But I was able to download & install nodejs, and the various "necessary tools" for its use, including "Chocolatey."
I have opened cmd prompts to "clean install" the client and server, but typing npm ci does nothing.
So, I'm stuck on Step #8 of installing the Developer Edition.
Any ideas re: how to proceed?
This is probably a rookie mistake, and we'll all have a good laugh later, but I'm no where near starting the 15 minute 'Create a starter widget' tutorial.
