Should we use v-model to modify Vuex store?

https://vuex.vuejs.org/guide/forms.html

When using Vuex in strict mode, it could be a bit tricky to use v-model on a piece of state that belongs to Vuex.

The “Vuex way” to deal with it is binding the <input>‘s value and call an action on the input or change event.

Be sure to check out the simple “Two-way Computed Property” example on that page:

<input v-model="message">

computed: {
  message: {
    get () {
      return this.$store.state.obj.message
    },
    set (value) {
      this.$store.commit('updateMessage', value)
    }
  }
}
