A style loader for esbuild, support for CSS, SCSS, LESS, Stylus, and CSS Modules.

## Features

- [x] Zero configuration
- [x] Support for CSS Modules
- [x] Support for LESS `builtin`
- [x] Support for CSS
- [x] Autoprefixer for CSS
- default: `ios >= 11, android >= 5, chrome >= 54`
- [x] Support sourceMap
- [x] Fast compiler engine by [lightningcss](https://lightningcss.dev/)

## Default behavior

The following rules enable css-modules

1. The file name ends with `/.modules?\.(css|less|scss|sass|styl)/`
2. The file query contains `modules` or `modules=true`
- Can be used with plugins [esbuild-plugin-auto-css-modules](https://www.npmjs.com/package/esbuild-plugin-auto-css-modules)

```ts
import styles from './style.css?modules';
import styles from './style.module.css';
import styles from './style.modules.css';
import styles from './style.less?modules';
import styles from './style.module.less';
import styles from './style.modules.less';
```

Normal CSS files are not treated as CSS Modules

```ts
import './style.css';
import './style.less';
import styles from './style.css';
import styles from './style.less';
```

## Usage

```ts
import { build } from 'esbuild';
import { styleLoader } from 'esbuild-style-loader';

const buildOptions = {
plugins: [
styleLoader({
filter: /\.(css|less|scss|sass|tyss)(\?.*)?$/,
/**
* Process file results from other plugins namespace
*/
namespace: ['native-component', 'file'],
/**
* The browser setting for lightningcss
*/
browsers: 'ios >= 11, android >= 5, chrome >= 54',
cssModules: {
pattern: process.env.CI_TEST === 'test' ? '[name]__[local]' : '[local]__[hash]',
},
/**
* The public path for absolute paths in css
*/
publicPath: __dirname,
}),
],
};
```

if you want to use absolute paths, you can specify the `publicPath` option
