Rules

@synbydesign-eslint/restrict-asset-import

Requires that CSS assets are co-located with a component and the CSS asset matches the same name. By default, the rule will match files with the extension .css, .scss, .module.css, and .module.scss.

// App.tsx
import "./App.css"; // OK!
import "./App.scss"; // OK!
import styles from "./App.module.css"; // OK!
import scssStyles from "./App.moulde.scss"; // OK!

export const App = () => {
  return <div>Hello world</div>;
};

Incorrect

// App.tsx
import "./Foo.css"; // Fail: different name
import "./Foo.scss"; // Fail: different name
import styles from "./Foo.module.css"; // Fail: different name
import scssStyles from "./Foo.moulde.scss"; // Fail: different name

import "./other/directory/App.css"; // Fail: different directory
import "./other/directory/App.scss"; // Fail: different directory
import styles from "./other/directory/App.module.css"; //Fail: different directory
import scssStyles from "./other/directory/App.moulde.scss"; // Fail: different directory

export const App = () => {
  return <div>Hello world</div>;
};
