type/no-floating-promises

Disallow floating (unhandled) Promises

Bad · Good

Default severity: warning
Presets: nuxt, opinionated
Automatic fix: None; review the suggested change
Applies to: Type information in Vue SFC scripts and templates, for the constructs shown below
Options: No rule-specific options. Severity and preset selection are configurable.

Type-aware checks use the native Corsa runtime and the TypeScript project. typeAware alone does not enable an opt-in rule.

Configuration (Vite+)

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

export default defineConfig({
  lint: {
    vize: {
      "preset": "incremental",
      "rules": {
        "type/no-floating-promises": "warn"
      },
      "typeAware": true
    },
  },
});

vp run lint

Bad

The async save function returns a Promise, but the standalone save() call neither awaits nor returns it and does not explicitly mark intentional disposal.

<script setup lang="ts">
async function save(): Promise<void> {}
save();
</script>

Good

void save() explicitly marks the fire-and-forget intent accepted by this rule. This is an explicit disposal marker, not a rejection handler.

<script setup lang="ts">
async function save(): Promise<void> {}
void save();
</script>

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