jss-camel-case

What is jss-camel-case?

The jss-camel-case npm package is a plugin for JSS (JavaScript Style Sheets) that converts camelCased property names to dash-separated (kebab-case) names. This is useful for writing CSS-in-JS styles in a more JavaScript-friendly syntax while ensuring compatibility with CSS standards.

What are jss-camel-case's main functionalities?

Convert camelCase to kebab-case

This feature allows you to write styles in camelCase and have them automatically converted to kebab-case. In the example, `backgroundColor` and `fontSize` are converted to `background-color` and `font-size` respectively.

const jss = require('jss').default;
const camelCase = require('jss-camel-case').default;

jss.use(camelCase());

const styles = {
  button: {
    backgroundColor: 'blue',
    fontSize: '14px'
  }
};

const sheet = jss.createStyleSheet(styles).attach();
console.log(sheet.toString());
