How can I implement CSS-in-JS with Vue for reactivity?

You can use libraries like Vue styled-components or Emotion to implement CSS-in-JS in Vue. They allow you to write CSS directly in your JavaScript files, making styles reactive.

Can you give me an example of how to use styled-components in Vue?

Sure! First, install the library using npm. Then, you can create styled components like this:

import styled from 'vue-styled-components';

const Button = styled.button`
  background-color: ${props => props.primary ? 'blue' : 'gray'};
  color: white;
`;

You can then use <Button primary> in your template.

What are the benefits of using CSS-in-JS over traditional CSS?

CSS-in-JS allows for scoped styles, dynamic styling based on props, and easier maintenance since styles are co-located with components.

Are there any performance concerns with CSS-in-JS?

Yes, there can be performance concerns, especially with large applications. It's important to optimize and avoid excessive re-renders.
