Can I use Vue2 and Vue3 in same project ?

Yes, it is possible to use Vue2 and Vue3 in the same project. However, it is important to note that they are not compatible with each other, so you will need to use them separately.

To use Vue3 in your Laravel project, you can install it via npm:

npm install vue@next

Then, you can create a new Vue3 instance in your JavaScript file:

import { createApp } from 'vue';

const app = createApp({
  // your Vue3 code here
});

app.mount('#app');

To use Vue2 in the same project, you can continue to use the existing Vue2 instance:

import Vue from 'vue';

new Vue({
  // your Vue2 code here
}).$mount('#app');

Just make sure to keep the Vue2 and Vue3 code separate and avoid using them together in the same component.
