[Bug]: TypeScript syntax error when installing sidebar component in JavaScript project

[YYelf]

Reproduction

npm create vite@latest my-project

Describe the bug

I'm trying to install the shadcn-vue sidebar component in a pure JavaScript project. Although I've set "typescript": false in my components.json , the installation still fails with the following error:

[@vue/compiler-sfc] Failed to resolve import source ".". 

ui/sidebar/Sidebar.vue                                              
12 |  })                                                            
13 |                                                                
14 |  const props = withDefaults(defineProps<SidebarProps>(), {     
   |                                         ^^^^^^^^^^^^           
15 |    side: "left",                                               
16 |    variant: "sidebar",

The error is clearly due to the generated component using TypeScript syntax defineProps() , while my project is a pure JavaScript project.

I'm using the latest version of shadcn-vue (installed via npx shadcn-vue@latest add sidebar ).

I've already checked similar issues ( #1060 and #1144 ), but these didn't provide an effective solution.

Environment Information

• shadcn-vue version: latest
• Vue version: ^3.5.22
• Project type: JavaScript (not TypeScript)
• Operating System: Windows

Steps to Reproduce

1. Create a new Vue JavaScript project (not TypeScript)
2. Install shadcn-vue and configure "typescript": false in components.json
3. Run npx shadcn-vue@latest add sidebar
4. Observe installation failure with the error message shown above
   Expected Behavior When "typescript": false is set in components.json , the generator should create JavaScript versions of components without TypeScript syntax.

Possible Solution Could the component generator be modified to ensure that components generated in JavaScript mode do not contain TypeScript syntax?
