Configuration (Vite+)

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

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

vp run lint

Bad

setup() calls onMounted() after await loadData(); with no current component instance at that point, the hook is never registered.

<script lang="ts">
import { onMounted } from 'vue'
export default {
  async setup() {
    await loadData()
    onMounted(() => {})
  },
}
</script>

Good

onMounted() is registered before the first await, while setup() still runs synchronously for the component.

<script lang="ts">
import { onMounted } from 'vue'
export default {
  async setup() {
    onMounted(() => {})
    await loadData()
  },
}
</script>

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