Vue component architecture

Just started exploring Vue last night, so the answer might be obvious.

I came across components with this layout:

<template>
  <Slider v-model="value"/>
</template>

<script>
import Slider from '@vueform/slider'

export default {
  components: { Slider },
}
</script>

<style src="@vueform/slider/themes/default.css" />

and also components structured like a JS object:

app.component('button-counter', {
  data() {
    return {
      count: 0
    }
  },
  template: `
    <button @click="count++">
      You clicked me {{ count }} times.
    </button>`
})

Is there any practical difference between them? Is one preferred over the other? Does it relate more to Vue2 or Vue3?

Answer №1

The specific structure known as SFC single file component :

<template>
...
</template>

<script>
...
</script>

<style src="@vueform/slider/themes/default.css" />

This format needs a bundler like webpack or vue cli for compilation, whereas the alternative syntax (as seen in your Vue 3 example) is suitable for defining global components when using Vue through CDN.

For larger projects, it is recommended to use the first syntax.
