### TypeScript Aware Rules

Type aware rules are enabled when a `tsconfig.eslint.json` is found in the project root. Refer to [this file](https://github.com/antfu/eslint-config/blob/main/packages/typescript/index.js#L17).
Type aware rules are enabled when a `tsconfig.eslint.json` is found in the project root. If you want to enable it while have no `tsconfig.eslint.json` in the project root, you can change tsconfig name by modifying `ESLINT_TSCONFIG` env.

```js
// .eslintrc.js
process.env.ESLINT_TSCONFIG = 'tsconfig.json'

module.exports = {
extends: '@antfu'
}
```
