How can I implement theme switching in my Vue.js application?

You can implement theme switching in Vue.js by using a combination of Vue's reactive data properties and CSS classes.

Can you show me a simple example?

Sure! You can create a data property for the theme and toggle it based on user input. Here's a basic example:

data() {
  return {
    theme: 'light'
  };
},
methods: {
  toggleTheme() {
    this.theme = this.theme === 'light' ? 'dark' : 'light';
  }
}

Then, bind the theme to your class in the template.

What about saving the user's theme preference?

You can use localStorage to save the user's theme preference. When the app loads, check localStorage and set the theme accordingly.
