In the current configuration, eslint cannot deal with TypeScript. The following steps enable TypeScript support.

• Run npm install --save-dev @vue/eslint-config-typescript
• Adapt the ESLint config:
  • Remove "parser": "@babel/eslint-parser" from the parserOptions
  • Add "@vue/typescript/recommended" to the extends key

Based on your file above, it would look like this:

{
  "root": true,
  "env": {
    "node": true
  },
  "extends": [
    "plugin:vue/essential",
    "eslint:recommended",
    "@vue/typescript/recommended"
  ],
  "parserOptions": {},
  "rules": {}
}

Depending on your ESLint version, the installation of @vue/eslint-config-typescript might result in a dependency conflict. With ESLint < 9 you'll have to install @vue/eslint-config-typescript@10
