How can I manage async requests in Vue with state management?
You can use Vuex for state management along with async actions to handle requests. Would you like a code example?
Yes, please provide a code example for making an async request.
Sure! Here's a simple example using Vuex:
// store.js
import Vue from 'vue';
import Vuex from 'vuex';
Vue.use(Vuex);
export default new Vuex.Store({
state: {
data: null,
loading: false,
},
mutations: {
SET_DATA(state, payload) {
state.data = payload;
state.loading = false;
},
SET_LOADING(state, payload) {
state.loading = payload;
},
},
actions: {
async fetchData({ commit }) {
commit('SET_LOADING', true);
const response = await fetch('https://api.example.com/data');
const data = await response.json();
commit('SET_DATA', data);
},
},
});
This code sets up a Vuex store with async actions to manage loading state and data.
How do I call the fetchData action in my component?
You can call the action in your component's lifecycle hook like this:
// MyComponent.vue
<template>
<div>
<button @click="loadData">Load Data</button>
<div v-if="loading">Loading...</div>
<div v-else>{{ data }}</div>
</div>
</template>
<script>
import { mapState, mapActions } from 'vuex';
export default {
computed: {
...mapState(['data', 'loading']),
},
methods: {
...mapActions(['fetchData']),
loadData() {
this.fetchData();
},
},
};
</script>
