type/no-unsafe-enum-assignment

Disallow assigning a non-enum value to an enum.

Applies to: Type information in Vue SFC scripts and templates, for the constructs shown below.

This rule reads type information from your TypeScript project (tsconfig.json), so the configuration sets typeAware: true. typeAware does not turn on opt-in rules by itself.

Bad

The binding is annotated as Color, but it is initialized with the number 1.

<script setup lang="ts">
enum Color {
  Red = 0,
  Green = 1,
}
const color: Color = 1;
</script>

Good

Color.Red is a member of the Color enum.

<script setup lang="ts">
enum Color {
  Red = 0,
  Green = 1,
}
const color: Color = Color.Red;
</script>

Configuration (Vite+)

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

export default defineConfig({}).withVue({
  linter: {
    "preset": "incremental",
    "rules": {
      "type/no-unsafe-enum-assignment": "warn"
    },
    "typeAware": true
  },
});

Then run vp run lint.
