Intellisense not working in template when not using "script setup"

[enodr]

Hi,

I have noticed that Intellisense is not working in template under two conditions:

• if the component doesn't have a <script setup></script> part but only <script></script>

with script setup (even if empty):

without script setup:

• if the component has a <script setup></script> part but props are defined then Intellisense stops working inside the template:

This is expected, Volar intellisense supports base on defineComponent, if you don't have, you can use experimentalImplicitWrapComponentOptionsWithDefineComponent option to tell Volar auto wrap component options by defineComponent.

tsconfig.json / jsconfig.json

{
  "compilerOptions": {
    // ...
  },
  "vueCompilerOptions": {
    "experimentalImplicitWrapComponentOptionsWithDefineComponent": true
  },
  "include": ["src/**/*.js", "src/**/*.ts", "src/**/*.d.ts", "src/**/*.vue"]
}

组件中，props不使用defineProps的形式还是会出现这个问题

The suggested solution by @johnsoncodehk is deprecated, and even though this is old I am still getting this issue.

The solution is to have both data option and a script with setup: vuejs/core#9296 (comment)
