npx @eslint/migrate-config .eslintrc.json 
Need to install the following packages:
@eslint/[email protected]
Ok to proceed? (y) y


Migrating .eslintrc.json
Also importing your .eslintignore file

Wrote new config to ./eslint.config.mjs

You will need to install the following packages to use the new config:
- globals
- @eslint/js
- @eslint/eslintrc

You can install them using the following command:

npm install globals @eslint/js @eslint/eslintrc -D

The following messages were generated during migration:
- The 'node' environment is used, but the sourceType is 'module'. Using sourceType 'module'. If you want to use CommonJS modules, set the sourceType to 'commonjs'.

✗ npm run lint

> [email protected] lint
> eslint . --ext .ts

(node:551532) ESLintIgnoreWarning: The ".eslintignore" file is no longer supported. Switch to using the "ignores" property in "eslint.config.js": https://eslint.org/docs/latest/use/configure/migration-guide#ignoring-files
(Use `node --trace-warnings ...` to show where the warning was created)

Oops! Something went wrong! :(
