VUE COMMAND LINE INTERFACE
run vue cli from anywhere

VUE GUI INTERFACE
run vue ui from project folder (or maybe anywhere not sure)


UPGRADING
1 First take a checkpoint snapshot commit to revert to if necessary
2 upgrade the vu ui cli tool: npm update -g @vue/cli
3 Then can do the upgrade inside it after running vue UI


LINTER ISSUES
=-=-=-=-=-=-=-
After an update I suddenly had a conflict between the linting in formatting document and the vue cli compiler:
....
TODO: LINTER ISSUES
	- On manual format of document with .vue extension the html template part shows multiple errors by linter
	- invoke the task vue-cli-service lint seems to fix the issues
	- Formatting the document ctrl-shift-i again reverses the fixes and seems to break it again
	- By break I mean these kinds of errors: Insert `·/` {
	"resource": "/c:/data/code/raven-client/ayanova/src/views/inventory-widget-edit.vue",
	"owner": "eslint",
	"code": "prettier/prettier",
	"severity": 4,
	"message": "Insert `·/`",
	"source": "eslint",
	"startLineNumber": 143,
	"startColumn": 16,
	"endLineNumber": 143,
	"endColumn": 16
}
....

I fucked with it a lot and surprisingly dont' think I've broken anything but the whole issue resolved (I think) when I changed the vetur setting:
from "js-beautify-html" or maybe it was "prettyhtml" to this:
"vetur.format.defaultFormatter.html": "prettier",

WORKING linter settings that keep both eslint and veture in sync even when formatting document:

todo: ONGOING search for memory leaks
	The 7 times system seems to work the best
	Excercise item a few times to settle it in memory, take heap snapshot, force gc, take total of 3 heap snapshots forcing gc each times
	Excercise item 7 times exactly, take 3 more heap snapshots forcing gc before each one
	Compare snapshot 6 to snapshot 3 look for Delta 7 times items to find leak
