@maa/monkey-css v0.1.1

Monkey.js + CSS

Import .css files in your Monkey.js project

Installation

npm install --save @maa/monkey-css

or

yarn add @maa/monkey-css

Usage

The stylesheet is compiled to .next/static/css. Monkey.js will automatically add the css file to the HTML. In production a chunk hash is added so that styles are updated when a new version of the stylesheet is deployed.

Without CSS modules

Create a next.config.js in the root of your project (next to pages/ and package.json)

// next.config.js
const withCSS = require('@maa/monkey-css');
module.exports = withCSS({
	/* config options here */
});

Create a CSS file style.css

.example {
	font-size: 50px;
}

Create a page file pages/index.js

import '../style.css';

export default () => <div className="example">Hello World!</div>;

With CSS modules

// next.config.js
const withCSS = require('@maa/monkey-css');
module.exports = withCSS({
	cssModules: true
});

Create a CSS file style.css

.example {
	font-size: 50px;
}

Create a page file pages/index.js

import css from '../style.css';

export default () => <div className={css.example}>Hello World!</div>;

With CSS modules and options

You can also pass a list of options to the css-loader by passing an object called cssLoaderOptions.

For instance, to enable locally scoped CSS modules, you can write:

// next.config.js
const withCSS = require('@maa/monkey-css');
module.exports = withCSS({
	cssModules: true,
	cssLoaderOptions: {
		importLoaders: 1,
		localIdentName: '[local]___[hash:base64:5]'
	}
});

Create a CSS file styles.css

.example {
	font-size: 50px;
}

Create a page file pages/index.js that imports your stylesheet and uses the hashed class name from the stylesheet

import css from '../style.css';

const Component = props => {
	return <div className={css.example}>...</div>;
};

export default Component;

Your exported HTML will then reflect locally scoped CSS class names.

For a list of supported options, refer to the webpack css-loader README.

PostCSS plugins

Create a next.config.js in your project

// next.config.js
const withCSS = require('@maa/monkey-css');
module.exports = withCSS({
	/* config options here */
});

Create a postcss.config.js

module.exports = {
	plugins: {
		// Illustrational
		'postcss-css-variables': {}
	}
};

Create a CSS file style.css the CSS here is using the css-variables postcss plugin.

:root {
	--some-color: red;
}

.example {
	/* red */
	color: var(--some-color);
}

When postcss.config.js is not found postcss-loader will not be added and will not cause overhead.

You can also pass a list of options to the postcss-loader by passing an object called postcssLoaderOptions.

For example, to pass theme env variables to postcss-loader, you can write:

// next.config.js
const withCSS = require('@maa/monkey-css');
module.exports = withCSS({
	postcssLoaderOptions: {
		parser: true,
		config: {
			ctx: {
				theme: JSON.stringify(process.env.REACT_APP_THEME)
			}
		}
	}
});

Configuring Monkey.js

Optionally you can add your custom Monkey.js configuration as parameter

// next.config.js
const withCSS = require('@maa/monkey-css');
module.exports = withCSS({
	webpack(config, options) {
		return config;
	}
});
