useCoreStore

A small Pinia store (id 'core') for your own, non-server named loading flags: one place to track "is anything loading" for work that has no request behind it (a client-side computation, a multi-step wizard), instead of ad-hoc local refs per screen.

Server work does not go through this store. A REST resource knows its own loading state (loading / isLoading(key)), and useIsLoading answers "is any of these resources busy" across the app, both read straight from the shared TanStack cache.

Quickstart

import { useCoreStore } from '@guebbit/vue-toolkit'

const core = useCoreStore()

core.setLoading('onboardingWizard', true)
core.getLoading('onboardingWizard') // true
core.isLoading() // true: at least one key is active
core.isLoading(['cart']) // false: nothing under that prefix is

core.setLoading('onboardingWizard', false)
core.isLoading() // false

Scoping with prefixes

isLoading() with no argument is "is the app doing anything at all", which is rarely what a screen wants to render: an unrelated background flag lights the same indicator as the one you care about. Pass prefixes to ask a narrower question:

const isBootLoading = computed(() => core.isLoading(['onboarding']))
const isUploading = computed(() => core.getLoading('onboardingWizard:avatar-upload'))

A prefix matches from the start of the key, so 'onboarding' covers every flag under it. Keep that in mind when naming: an unrelated onboardingV2 flag would answer to it too.

isLoading is a plain function rather than a computed, so it does not come out of storeToRefs: take it from the store itself, and call it inside a computed to stay reactive.

API

Property / method	Purpose
loadings	Ref: Record<string, boolean> of every tracked key.
isLoading(prefixes?)	true when a key is active; only keys starting with one of prefixes, or any key when omitted.
setLoading(key, value)	Sets one key's loading state. Returns the value stored.
getLoading(key)	Reads one key's loading state; an unknown key reads false.
resetLoadings()	Clears every tracked key.
