微前端（无界）入门

主应用通过props给子应用传值

父子应用通过eventBus通信

通过路由同步实现记录子应用的路由状态

主应用

main.ts:

import './assets/main.css'

import { createApp } from 'vue'
import { createPinia } from 'pinia'
import WujieVue from 'wujie-vue3'

import App from './App.vue'
import router from './router'

const app = createApp(App)

app.use(createPinia())
app.use(router)
app.use(WujieVue)

app.mount('#app')

index.vue:

<script setup>
import { onMounted, ref } from 'vue'
import WujieVue from 'wujie-vue3'
import './index.css'

const { bus } = WujieVue

const url = ref('http://localhost:3003/')
const props = ref({
  count: 0
})

const handleAdd = () => {
  props.value.count++
  bus.$emit('msg', {
    count: props.value.count
  })
}

onMounted(() => {
  bus.$on('msg-from-child', (payload) => {
    props.value.count = payload.count
  })
})
</script>

<template>
  <div>
    <button @click="() => handleAdd()">{{ props.count }}</button>
  </div>
  <div class="m-wujie">
    <WujieVue
      width="100%"
      height="100%"
      name="child"
      :url="url"
      :props="props"
      :sync="true"
    ></WujieVue>
  </div>
</template>

子应用

Index.vue:

<script setup>
import { ref, onMounted } from 'vue'
import './index.css'

const count = ref(0)
const handleGetProps = () => {
  console.log(window, window.$wujie.props.count)
}

const handleGetAdd = () => {
  count.value++
  window.$wujie?.bus.$emit('msg-from-child', {
    count: count.value
  })
}

onMounted(() => {
  window.$wujie?.bus.$on('msg', function (payload) {
    count.value = payload.count
  })
})
</script>

<template>
  <div class="m-home-wrap">
    <div class="m-home-toolbar">
      <button @click="() => handleGetProps()">获取props</button>
      <button @click="() => handleGetAdd()">{{ count }}</button>
    </div>
    <div class="m-home-demo"></div>
  </div>
</template>

<style></style>

效果：
