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).

Install the no-unused-imports plugin

Add unused-imports to the plugins section of your .eslintrc file

{
  "plugins": ["...", "unused-imports"]
}

add the following rules

"no-unused-vars": "off",
"unused-imports/no-unused-imports": "error",
"unused-imports/no-unused-vars": [
  "warn",
  { "vars": "all", "varsIgnorePattern": "^_", "args": "after-used", "argsIgnorePattern": "^_" }
    ],

Then add script to your package.json file

"scripts": {
   ...
   "fix-lint-errors": "eslint nx --fix"
},

from command line run the script

npm run fix-lint-errors

or

yarn fix-lint-errors
