> Example showing how to migrate an existing eslinrc.json to new flat file config for using ESLint v9 and above in a CommonJS project
This is the accompanying example project for the article on [migrating eslintrc to flat file config in a CommonJS project](https://tsmx.net/migrating-eslintrc-to-flat-config-in-commonjs/).
To follow along with the guide, clone this repo an inspect the branches for ESLint v8 (old eslintrc config) and v9 (new flat-file config).
**Note:** Since the needed dependencies change when migrating from ESLint v8 to v9 or vice versa, you'll need to do a `npm install` after switching the branch.
```bash
# clone the example project
git clone https://github.com/tsmx/eslintrc-to-flatfile.git
# check out/switch to the original ESLint v8 branch using eslintrc.json
git checkout eslint-v8
npm install
# check out/switch to the migrated ESLint v9 branch using new eslint.config.js
git checkout eslint-v9
npm install
```
