 - [WebStorm](https://www.jetbrains.com/webstorm/) also provides out-of-the-box support for both TypeScript and Vue. Other JetBrains IDEs support them too, either out of the box or via [a free plugin](https://plugins.jetbrains.com/plugin/9442-vue-js). As of version 2023.2, WebStorm and the Vue Plugin come with built-in support for the Vue Language Server. You can set the Vue service to use Volar integration on all TypeScript versions, under Settings > Languages & Frameworks > TypeScript > Vue. By default, Volar will be used for TypeScript versions 5.0 and higher.
