Vue store loading state

Installation

npm i @schoolmouv/vuex-awesome-async

Dans le main.js:

import VueState from '@schoolmouv/vuex-awesome-async';

Vue.use(VueState);

Usage

1. Wrap a store

import Vue from 'vue';
import { wrapStore } from '@schoolmouv/vuex-awesome-async';

const { wrapMutations, wrapActions, wrapGetters, wrapState } = wrapStore(
  'store',
);

const state = wrapState({});

const getters = wrapGetters({});

const actions = wrapActions({});

const mutations = wrapMutations({});

export default {
  state,
  getters,
  actions,
  mutations,
};

2. Use a loader component to display loading or error (exemple)

<template>
  <div class="loader" :class="{ 'is-loading': isLoading }">
    <slot :name="slotName">
      <div class="loading">
        <div class="icon-spinner3" v-if="isLoading"></div>
      </div>
      <div class="error" v-if="hasError">{{ errorMessage }}</div>
    </slot>
  </div>
</template>

<script>
export default {
  name: 'Loader',

  props: {
    store: {
      type: [Array, String],
      default: () => [],
    },
    errorMessage: {
      type: String,
      default: '',
    },
  },

  computed: {
    slotName() {
      if (this.isLoading) return 'loading';
      if (this.hasError) return 'error';
      return 'default';
    },

    storeArray() {
      return Array.isArray(this.store) ? this.store : [this.store];
    },

    isLoading() {
      if (this.$isServer) return false;
      return this.storeArray.reduce((loading, store) => {
        return loading || this.isStoreLoading(store);
      }, false);
    },

    hasError() {
      return (
        this.storeArray.reduce((loading, store) => {
          return loading || this.storeHasError(store);
        }, false)
      );
    },
  },
};
</script>

<Loader :store="['store1', 'store2']">
  <div>
    Async content to display
  </div>
  <div slot="error">
    An error occurred
  </div>
  <div slot="loading">
    Display custom logger
  </div>
</Loader>
