Let’s talk about how vuex modularizes coding + namespace

How does vuex modularize coding + namespace? Let’s take a brief look at this article, I hope it will be helpful to everyone!

Modular coding + namespace

Little a: "Why do you want to enable this? "Shan Yu: "Of course it is to make the code easier to maintain and to make the classification of various data more clear."

小a: "Then how can we achieveModular coding + namespace"

Shanyu: "That's all it takes"

namespaced: true

Put all the things in the Count component and Person component into the store

// Count的相关配置
export default {
    namespaced: true,
    actions: {
        // 奇数加法
        jiaodd(context, value) {
            if (context.state.sum % 2) {
                context.commit('JIA', value)
            }
        },
        // 延迟加
        jiaWait(context, value) {
            setTimeout(() => {
                context.commit("JIA", value)
            }, 500);
        },
    },
    mutations: {
        JIA(state, value) {
            state.sum += value
        },
        JIAN(state, value) {
            state.sum -= value
        },
    },
    state: {
        sum: 0, // 当前和
        school: '山鱼小学',
        subject: '前端',
    },
    getters: {
        bigSum(state) {
            return state.sum * 10
        }
    }
}

2. After opening the namespace, read the state data

  computed: {
     // 自己读取
    personList() {
      returnthis.$store.state.personAbout.personList;
    },
    sum() {
      returnthis.$store.state.countAbout.sum;
    },
  },
  // 借助mapState读取
computed: {
    ...mapState("countAbout", ["sum", "subject", "school"]), 
    ...mapState("personAbout", ["personList"]) 
  },

3. After opening the namespace, read the getters data in the component

  computed: {
      // 自己读取
    firstName() {
      returnthis.$store.getters["personAbout/firstPersonName"];
    }
  },
  methods: {
    // 借助mapGetters读取
    // 借助mapMutations生成对应的方法，方法种会调用相应的commit去联系mutations
    ...mapMutations('countAbout',{ increment: "JIA", decrement: "JIAN" }), // 对象式

    ...mapActions('countAbout',{ incrementOdd: "jiaodd", incrementWait: "jiaWait" }) //对象式

  },

4. After opening the namespace, call dispatch

methods: {
     // 直接dispath
    addWang() {
      constpersonObj= { id: nanoid(), name: this.name };
      this.$store.dispatch("personAbout/addNameWang", personObj);
      this.name="";
    },
  },
//借助mapGetters读取:
  computed: {
    ...mapGetters('countAbout',['bigSum'])
  },

5. After opening the namespace, call commit## in the component #

methods: {
    // 直接调用
    add() {
      constpersonObj= { id: nanoid(), name: this.name };
      this.$store.commit("personAbout/ADD_PERSON", personObj);
      this.name="";
    },
 }
  methods: {
    // 借助mapMutations生成对应的方法，方法种会调用相应的commit去联系mutations
    ...mapMutations('countAbout',{ increment: "JIA", decrement: "JIAN" }), // 对象式
      },
  }

I can only say that the modularization is very fragrant, the code is clearer and the data is more distinct, and the later maintenance is also very niue
