You can dispatch actions in components with this.$store.dispatch('action name'), or use the mapActions helper which maps component methods to store.dispatch calls.
For example, you can dispatch increment actions in counter component as below,
import { mapActions } from 'vuex'
export default {
// ...
methods: {
...mapActions([
'increment', // map `this.increment()` to `this.$store.dispatch('increment')`
// `mapActions` also supports payloads:
'incrementBy' // map `this.incrementBy(amount)` to `this.$store.dispatch('incrementBy', amount)`
]),
...mapActions({
add: 'increment' // map `this.add()` to `this.$store.dispatch('increment')`
})
}
}
