Vue3+TS+Vite 개발 기술: 상태 관리에 Vuex를 사용하는 방법

// store/index.ts
import { createStore } from 'vuex';

const store = createStore({
  // 定义state
  state: {
    count: 0,
  },
  // 定义mutations
  mutations: {
    increment(state) {
      state.count++;
    },
  },
  // 定义actions
  actions: {
    incrementAsync(context) {
      setTimeout(() => {
        context.commit('increment');
      }, 1000);
    },
  },
});

export default store;

// main.ts
import { createApp } from 'vue';
import App from './App.vue';
import store from './store';

createApp(App)
  .use(store)
  .mount('#app');

<template>
  <div>
    <p>Count: {{ count }}</p>
    <button @click="increment">Increment</button>
    <button @click="incrementAsync">Increment Async</button>
  </div>
</template>

<script>
import { mapState, mapMutations } from 'vuex';

export default {
  computed: {
    ...mapState(['count']),
  },
  methods: {
    ...mapMutations(['increment']),
    incrementAsync() {
      this.$store.dispatch('incrementAsync');
    },
  },
};
</script>
