no-unused-vars

Disallow unused variables.

✅

Extending "plugin:@typescript-eslint/recommended" in an ESLint configuration enables this rule.

Examples​

This rule extends the base eslint/no-unused-vars rule. It adds support for TypeScript features, such as types.

How to Use​

.eslintrc.cjs
module.exports = {
  "rules": {
    // Note: you must disable the base rule as it can report incorrect errors
    "no-unused-vars": "off",
    "@typescript-eslint/no-unused-vars": "warn"
  }
};

Options​

See eslint/no-unused-vars options.
