What are the differences between local and global mixins in Vue.js?

Local mixins are defined within a specific component and only affect that component, while global mixins are applied to all components in the application.

Can you give me an example of a local mixin?

Sure! A local mixin can be defined in a component like this:

const localMixin = {
  data() {
    return { message: 'Hello from local mixin!' };
  },
  created() {
    console.log(this.message);
  }
};

export default {
  mixins: [localMixin],
  // other component options
};

What about a global mixin?

A global mixin can be defined like this:

Vue.mixin({
  created() {
    console.log('Global mixin created hook!');
  }
});

This will run the created hook for every component.

Are there any downsides to using global mixins?

Yes, global mixins can lead to conflicts and make debugging harder since they affect all components. It's best to use them sparingly.
