bun-css-modules
Allows you to import CSS Modules directly into Bun.
This loader uses the incredibly fast Rust based Lightning CSS under the hood.
Installation
To install dependencies:
bun add -D bun-css-modulesCreate cssLoader.ts:
import { plugin } from 'bun'
import { moduleCssLoader } from 'bun-css-modules'
plugin(moduleCssLoader())You can pass in options to customize some settings via moduleCssLoader({ [optionName]: <value> }). The defaults are:
{
filePattern = /\.module.css$/,
browserlistQuery = [
'last 4 chrome version',
'last 4 firefox version',
'last 2 safari version',
],
}Create a bunfig.toml if you don't have one and add:
preload = ["./cssLoader.ts"]Example Usage
Example using Hono JSX:
/* Button.module.css */
.buttonBase {
appearance: none;
font-family: inherit;
font-size: inherit;
color: inherit;
border-radius: 4px;
}
.primary {
composes: buttonBase;
background: blue;
color: white;
border: 1px solid purple;
}import styles from './Button.module.css'
export function PrimaryButton({ children }) {
return <button class={styles.primary}>{children}</button>
}Include styles once in your head via the special cssText property.
import buttonStyles from 'src/components/Button/Button.module.css'
import tableStyles from 'src/components/Table/Table.module.css'
export function Layout({ title, children }: LayoutProps) {
return (
<html>
<head>
<title>{title}</title>
<style>{buttonStyles.cssText}</style>
<style>{tableStyles.cssText}</style>
</head>
<body>{children}</body>
</html>
)
}import { PrimaryButton } from 'src/components/Button'
import styles from './SignUpPage.module.css'
function SignUpPage() {
return (
<div class={styles.container}>
<h1>Sign up</h1>
<PrimaryButton>Sign up</PrimaryButton>
{/* One-off page styling can just be included here */}
<style>{styles.cssText}</style>
</div>
)
}Typescript
Add an ambient file if you don't have one, e.g. app.d.ts:
declare module '*.module.css' {
const styles: {
cssText: string
[className: string]: string
}
export default styles
}And include it in your tsconfig.json:
{
"compilerOptions": {
"esModuleInterop": true,
"strict": true,
"baseUrl": ".",
"types": ["bun-types", "./app.d.ts"]
}
}
