Vue provides a special file format to combine the template, logic, and styling of a component in a single file. This format is called Single-File Component (SFC) also known as *.vue file.
Component.vue
<script setup>
import { ref } from 'vue'
const count = ref(0)
</script>
<template>
<p class="greeting">{{ count }}</p>
</template>
<style scoped>
.counter {
color: orangered;
}
</style>
This format is very convenient for small components, but it can become a bit overwhelming for larger components. In this case, you can split your SFC into multiple files using the src attribute to import an external file for a language block:
Component.vue
<script src="./script.js"></script>
<template src="./template.html"></template>
<style scoped src="./styles.css"></style>
This approach doesn't work with the
<script setup> block. Compiler macros like defineProps or defineEmits are compiler macros only usable inside <script setup>.But you can import any JavaScript/Typescript file:Component.vue
<script setup lang="ts">
defineProps<{ msg: string }>()
import { msg } from './script.ts'
</script>
<template src="./template.html"></template>
<style scoped src="./styles.css"></style>
Try it yourself:
I personally never needed and used this feature, but I think it's good to know that it exists.Instead, I prefer to use Composition API to extract shared logic in a separate file or split the component into multiple components.
