Use Vuex With Composition API Helpers
Robert Shaw
Posted on December 10, 2020
Recently, I'm focus on build a new wheel, I implement useXXX helpers for Vuex, and I'm consider about to contribute in Vuex, then i found that, the useXXX helpers proposal already exist nearly eight months.
checkout https://github.com/vueblocks/vue-use-utilities#vuex
@vueblocks/vue-use-vuex
- Use Vuex With Composition API Easily. It build on top of vue-demi
& @vue/compostion-api
. It works both for Vue 2 & 3, TypeScript Supported too.
useVuex
-
useState
- same asmapState
-
useGetters
- same asmapGetters
-
useMutations
- same asmapMutations
-
useActions
- same asmapActions
useStore
-
useStore
- same as Vuex 4.x composition api useStore
Usage
useState
import { useVuex } from '@vueblocks/vue-use-vuex'
export default {
// ...
setup () {
// Use the useState as you would use mapState
const { useState } = useVuex()
return {
// mix this into the outer object with the object spread operator
...useState({
// arrow functions can make the code very succinct!
count: state => state.count,
// passing the string value 'count' is same as `state => state.count`
countAlias: 'count',
// to access local state with `this`, a normal function must be used
countPlusLocalState (state) {
return state.count + this.localCount
}
}),
...mapState([
// map count<ComputedRef> to store.state.count
'count'
])
}
}
}
useGetters
import { useVuex } from '@vueblocks/vue-use-vuex'
export default {
// ...
setup () {
// Use the useGetters as you would use mapGetters
const { useGetters } = useVuex()
return {
// mix the getters into outer object with the object spread operator
...useGetters([
'doneTodosCount',
'anotherGetter',
// ...
]),
// if you want to map a getter to a different name, use an object:
...mapGetters({
// map `doneCount<ComputedRef>` to `this.$store.getters.doneTodosCount`
doneCount: 'doneTodosCount'
})
}
}
}
useMutations
import { useVuex } from '@vueblocks/vue-use-vuex'
export default {
// ...
setup () {
// Use the useMutations as you would use mapMutations
const { useMutations } = useVuex()
return {
...useMutations([
'increment', // map `increment()` to `this.$store.commit('increment')`
// `mapMutations` also supports payloads:
'incrementBy' // map `incrementBy(amount)` to `this.$store.commit('incrementBy', amount)`
]),
...useMutations({
add: 'increment' // map `add()` to `this.$store.commit('increment')`
})
}
}
}
useActions
import { useVuex } from '@vueblocks/vue-use-vuex'
export default {
// ...
setup () {
// Use the useActions as you would use mapActions
const { useActions } = useVuex()
return {
...useActions([
'increment', // map `increment()` to `this.$store.dispatch('increment')`
// `mapActions` also supports payloads:
'incrementBy' // map `incrementBy(amount)` to `this.$store.dispatch('incrementBy', amount)`
]),
...useActions({
add: 'increment' // map `add()` to `this.$store.dispatch('increment')`
})
}
}
}
namespacing
also support
// Get namespaced component binding helpers in useVuex
import { useVuex } from '@vueblocks/vue-use-vuex'
export default {
setup () {
const { mapState, mapActions } = useVuex('some/nested/module')
return {
// look up in `some/nested/module`
...mapState({
a: state => state.a,
b: state => state.b
})
// look up in `some/nested/module`
...mapActions([
'foo',
'bar'
])
}
}
}
It seems familiar right? Yeah, You could think of @vueblocks/vue-use-vuex
as a wrapper of Vuex Helpers
But, I'm didn't think too much about type safety, and i am still learning TypeScript. If you're interested it, Please help me improve it.
