Configuration (Vite+)

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

export default defineConfig({
  vue: {
    linter: {
      "preset": "incremental",
      "rules": {
        "script/require-slots-as-functions": "error"
      }
    },
  },
});

vp run lint

Bad

render returns this.$slots.default without calling it, which was the Vue 2 vnode array.

<script lang="ts">
export default {
  render() {
    return this.$slots.default
  }
}
</script>

Good

render calls this.$slots.default() and uses the returned vnode.

<script lang="ts">
export default {
  render() {
    return this.$slots.default()
  }
}
</script>

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