Is it possible to use vue3(vue_next) in intellij (or webstorm)?

Yes, it's possible

The IDE uses Vue CLI to create a project; the default setup is a result of running npx --package @vue/cli vue create --default. If you'd like to create a Vue 3 app, please make sure to uncheck the Use the default project setup checkbox in the New Project dialog - you will be prompted in the Run tool window to choose the desired options, including the Vue.js version

I tried this but IntelliJ 2001.3 is not working with Vue 3.2.29 very well? Has anyone figured this out? Below the context doesn't work in a .js file.

Vue.createApp({data(){}}).mount('#myApp');

Please could you elaborate on this? What doesn't work namely?

I can run the app and it works but there seems to be an issue with context? The package JSON is also provided for your review.

Hmm... The global Vue object is normally only available when using CDN builds. And you are using Vue cli, aren't you? In this case, you need importing modules, like

import { createApp } from 'vue'


createApp({...}).mount('#app')

I'm using the CDN?
