vue import组件的使用

1新建/src/component/firstcomponent.vue

<template>
  <div id="firstcomponent">
    <h1>I am a title.</h1>
    </div>
</template>

2在app.vue引入组件 并且注册

<script>
import firstcomponent from './component/firstcomponent.vue'

export default {
  components: { firstcomponent }
}

</script>

3 在app.vue的在<template></template>内加上<firstcomponent></firstcomponent>

<template>
  <div id="app">
        <firstcomponent></firstcomponent>
  </div>
</template>
