jss-plugin-rule-value-function

What is jss-plugin-rule-value-function?

The jss-plugin-rule-value-function package is a plugin for JSS (JavaScript Style Sheets) that allows you to use functions as values in your style rules. This can be particularly useful for dynamic styling based on props or other runtime conditions.

What are jss-plugin-rule-value-function's main functionalities?

Dynamic Styling

This feature allows you to define styles that can change dynamically based on the properties passed to the component. In this example, the button's color and background color are determined by the props `color` and `bgColor`.

const styles = {
  button: {
    color: props => props.color,
    backgroundColor: props => props.bgColor
  }
};

const useStyles = createUseStyles(styles);

function Button(props) {
  const classes = useStyles(props);
  return <button className={classes.button}>Click me</button>;
}

Conditional Styling

This feature allows you to apply conditional styling based on the properties. In this example, the button's color and background color change based on whether the `isPrimary` prop is true or false.

const styles = {
  button: {
    color: props => props.isPrimary ? 'blue' : 'gray',
    backgroundColor: props => props.isPrimary ? 'lightblue' : 'lightgray'
  }
};

const useStyles = createUseStyles(styles);

function Button(props) {
  const classes = useStyles(props);
  return <button className={classes.button}>Click me</button>;
}
