👨‍💻Usage

Use Vue2 components in Vue3

1. Create an empty element and define its id for mounting the Vue2 component
2. Use Vue2InVue3 to convert Vue2 component to Vue3
3. Mount the component to Vue3

<template>
  <div>
    <h1>VUE 3 Project</h1>
    <!-- Create an empty element to mount the Vue2 component, and assign a value to the element’s id -->
    <div id="content"></div>
    <!-- Components from Vue 2 to Vue 3 -->
    <conent-in-vue3
      :dataProps="num"
      :methodProps="propsFunc"
      @myEvent="emitFunc"
    />
  </div>
</template>

<script>
// Vue2 components Content
import Content from "@v2b/Content";
// use Vue2InVue3
import {Vue2InVue3} from "emp-vuett";
// Pass in Vue2 component and empty element id to Vue2InVue3
const ContentInVue3 = Vue2InVue3(Content, "content");

export default {
  name: "App",
  components: {
    // Mount the converted Vue2 component
    "conent-in-vue3": ContentInVue3,
  },
  data() {
    return {
      component: Content,
      num: 0,
    };
  },
  methods: {
    propsFunc() {
      console.log("Vue3 to Vue2 Method Props");
    },
    emitFunc() {
      this.num++;
    },
  },
  setup() {},
  mounted() {},
};
</script>

Precautions for using Vue2 components by Vue3:

Vue2 Use the custom event passed by Vue3 to change the function name kebab-case to camelCase and add the prefix on For example: calling @my-event needs to be written as onMyEvent

The Vue2 component used above:

<template>
  <div>
    <div class="v2box">{{ title }}</div>
    <button class="button" @click="add">Vue2 Add Button</button>
    <div class="v2box">Prop: {{ dataProps }}</div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      title: "Vue2 Component",
    };
  },
  props: {
    dataProps: { type: Number, required: false },
    methodProps: { type: Function, required: false },
  },
  methods: {
    add() {
      // Vue2 uses the custom event passed by Vue3 to change the function name kebab-case to camelCase and add the prefix on
      // For example: calling @my-event needs to be written as onMyEvent
      this.$emit("onMyEvent");
    },
  },
  mounted: function () {
    this.methodProps && this.methodProps();
  },
};
</script>

<style>
.v2box {
  font-size: 38px;
  color: green;
  font-weight: bold;
}
.button {
  width: 200px;
  padding: 20px 0;
}
</style>
