Vue Tip: Use Two Script Blocks

If you are using the new <script setup> syntax, you may run into a case where you need some Options API functionality. In this case, it’s possible to add an additional <script> block to your component. Vue will mix the two together for you, so the Composition API code and Options API code can remain separate.

You may need a regular <script> block in these cases:

  • Use the Options API to declare options that cannot be expressed in <script setup>, for example, inheritAttrs or custom options enabled via plugins.
  • Run side effects or create objects that should only execute once because setup() is run for every component.
  • Declare named exports which allow exporting multiple things from one file.
<script>
// Normal <script> using Options API, executed in module scope (only once)
runSideEffectOnce()

// Here you can declare additional options
export default {
  name: 'MyComponent',
  inheritAttrs: false,
  customOptions: {}
}
</script>

<script setup>
// Composition API: executed in setup() scope (for each instance)
import { ref } from 'vue';
console.log('Setting up new component instance');
const count = ref(0);
</script>

This feature is officially supported and documented.
