Using unused-imports plugin and unused-imports/no-unused-imports-ts rule, eslint --fix will remove the imports.

Here is an example repo which --fix removes the unused imports.

https://github.com/moshfeu/eslint-ts-unused-imports

Setup

yarn add -D eslint-plugin-unused-imports

// eslint.config.js

import tseslint from "typescript-eslint";
import unusedImports from "eslint-plugin-unused-imports";

export default tseslint.config(
  {
    plugins: {
      "unused-imports": unusedImports,
    },
    rules: {
      "unused-imports/no-unused-imports": "warn",
    },
  }
);

Old answer

eslint has a built-in fix option.

eslint ... --fix

If rules contains no-unused-vars, eslint will "fix" the unused import by removing them (along with other auto fixes).
