What steps should be taken to configure ESLint properly when encountering unnecessary warnings in <script setup>?

After transitioning to Vue3 from a traditional <script> setup to <script setup>, I am encountering numerous warnings from ESLint. Specifically, any declarations that are not utilized within the <script setup> section trigger the

@typescript-eslint/no-unused-vars
warning.

One particular instance is:

WARNING in src/layouts/Infinote.vue:105:8
@typescript-eslint/no-unused-vars: 'NoteComponent' is defined but never used.
    103 | import { DateTime } from 'luxon'
    104 | import { useQuasar } from 'quasar'
  > 105 | import NoteComponent from 'components/Note.vue'
        |        ^^^^^^^^^^^^^
    106 | import _ from 'lodash'
    107 |

This occurs for components that are actually being utilized in the <template>.

The suggested "solution" of globally disabling

@typescript-eslint/no-unused-vars
is not ideal. Is there a proper method to inform ESLint about the functionality of <script setup>?

Answer №1

If you're looking to activate the vue/script-setup-uses-var feature, you can do so with the help of the eslint vue plugin known as eslint-plugin-vue.
