Configuration (Vite+)

import { defineConfig } from "@vizejs/vite-plugin/vite-plus";

export default defineConfig({
  vue: {
    linter: {
      "preset": "incremental",
      "rules": {
        "script/no-watch-after-await": "error"
      }
    },
  },
});

vp run lint

Bad

watch() is created after await loadData() and its stop handle is discarded, so the watcher is never stopped with the component.

<script lang="ts">
import { watch } from 'vue'
export default {
  async setup(props) {
    await loadData()
    watch(() => props.id, reload)
  },
}
</script>

Good

The watcher is created before the first await, so Vue stops it when the component unmounts.

<script lang="ts">
import { watch } from 'vue'
export default {
  async setup(props) {
    watch(() => props.id, reload)
    await loadData()
  },
}
</script>

Good avoids this rule's finding under the configuration above; other rules may still report diagnostics.
