type/no-mixed-enums

Disallow mixing string and numeric enum members.

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 enum mixes a numeric member with a string member.

<script setup lang="ts">
enum Mixed {
  A = 0,
  B = "b",
}
</script>

Good

Both members are numeric, so the enum has one value domain.

<script setup lang="ts">
enum Mixed {
  A = 0,
  B = 1,
}
</script>

Configuration (Vite+)

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

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

Then run vp run lint.
