Eslint no-unused-vars error shows for used interface in Vue
Solution:
EsLint default no-unused-vars has an bug, that reproduces like you explain. According to my source [1] it should be fixed by using @typescript-eslint/no-unused-vars like so:
overrides: [ // Fix no-used-vars when importing ts types in .vue files { files: ["*.vue"], rules: { 'no-unused-vars': 'off', '@typescript-eslint/no-unused-vars': 'error' } }]Source [2] is another question on same topic. There, my solution [1] is one option among others. In [2] and [3] it is said you need the @typescript-eslint/eslint-plugin and @typescript-eslint/parser installed like so:
npm install --save-dev eslint @typescript-eslint/parser @typescript-eslint/eslint-pluginSource:
