@wire or imperative? The decision in four minutes
The shortest useful answer to the most-asked LWC question, with one demo component built both ways.
On this page
One component, built twice. The @wire version is nine lines shorter, caches
for free, and refreshes reactively when the tracked parameter changes. The
imperative version fires exactly when told, which is the only version that
works for a button click, a confirm dialog, or anything that must not run on
render.
The rule that falls out: @wire for reading state the page is about,
imperative for actions the user takes. If you are calling refreshApex on a
timer to make a wire behave imperatively, you wanted the other one.
