const mixin = {
  data() {
    return {
      message: "geyao",
    };
  },
  created(){
    console.log("我是mixin")
  }
};
export default {
  name: "App",
  mixins: [mixin],
  components: {
    HelloWorld,
  },
  data() {
    return {
     
    };
  },
   created(){
    console.log("我是app")
  }
};
</script>

<style>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
