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>
