type/no-deprecated

Disallow use of deprecated declarations.

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

legacy is marked @deprecated, and the call still uses that declaration.

<script setup lang="ts">
/** @deprecated use current() */
function legacy(): number {
  return 1;
}
const legacyValue = legacy();
</script>

Good

current has no deprecation mark, so the call uses a supported declaration.

<script setup lang="ts">
function current(): number {
  return 1;
}
const currentValue = current();
</script>

Configuration (Vite+)

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

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

Then run vp run lint.
