vuex-help

a plugin offers more natural API for Vuex.

Requirements

• Vue.js (v2.0.0+)
• Vuex (v2.0.0+)
• Vue.use(Vuex) is installed
• All Vuex state, getters and actions are organized into Vuex modules.

Motivations

Improve some of the difficulties of the existing api and mapXXX helpers.

1. bad readability
2. magic strings are hard to maintain and refactor
3. can't navigate to the source in the IDE

Usage

minimal example how to access actions and mutations without using mapXX helpers and magic string

export default {
  computed: {
    cart () {
      const { cartProducts: products, cartTotalPrice: total } = this.$h.getters.cart
      const { checkoutStatus } = this.$h.state.cart
      return {
        products,
        total,
        checkoutStatus
      }
    }
  },
  methods: {
    checkout (products) {
      this.$h.dispatch.cart.checkout(products)
    }
  }
}

note: v0.2.4 supports two different helper formats. see Api documentation for more detail.

<div class="cart">
    <h2>Your Cart</h2>
    <p v-show="!cart.products.length"><i>Please add some products to cart.</i></p>
    <ul>
      <li
        v-for="product in cart.products"
        :key="product.id">
        {{ product.title }} - {{ product.price | currency }} x {{ product.quantity }}
      </li>
    </ul>
    <p>Total: {{ cart.total | currency }}</p>
    <p><button :disabled="!cart.products.length" @click="checkout(cart.products)">Checkout</button></p>
    <p v-show="cart.checkoutStatus">Checkout {{ cart.checkoutStatus }}.</p>
  </div>
