How are form values processed in Vuex?

In Vuex, form values are usually handled through data binding between the component and the store.

The component commits changes to form values via mutations. Mutations are synchronous functions that directly modify the store's state.

For asynchronous operations, such as saving form data to a server, actions are used. Actions can contain asynchronous code and call mutations to change the state.

Component -> Dispatch action -> Commit mutation -> Change state

Example:

In the component:

<template>
  <input v-model="name">
</template>

<script>
export default {
  computed: {
    name: {
      get() {
        return this.$store.state.form.name;
      },
      set(value) {
        this.$store.commit('updateName', value);
      }
    }
  }
}
</script>

In Vuex store:

const store = new Vuex.Store({
  state: {
    form: {
      name: ''
    }
  },
  mutations: {
    updateName(state, value) {
      state.form.name = value;
    }
  }
});

Alternatively, you can use the component's local state to manage the form and then send the final form data to Vuex with a single action. This approach is often preferable for more complex forms to avoid excessive mutations and Vuex state updates.
