Link to minimal reproduction

No response

Any additional comments?

it happends when I update the extension to version 2.1.x, and disappears using version 2.0.x.

Could you provide a minimal reproduction for it?

[GnaugGnay]

@KazariEX here is a demo for you

[KazariEX]

This is a known limitation, we deliberately do not support decorators to avoid overly complex code. However, since I don't know if it can obtain the correct type (or any) before 2.1, I don't know how to fix it.

@KazariEX
I think, you guys should at least provide an option like "suppressTemplateIndexError" for us old-vue-version users. I really appreciate your works on it, but this error lints almost drive me crazy.

[KazariEX]

How about skipTemplateCodegen?

[GnaugGnay]

@KazariEX Better name than mine!

[KazariEX]

This is an existing feature, you can configure it in your tsconfig.json:

"vueCompilerOptions": {
	"skipTemplateCodegen": true
}

Could you tell me if using components imported with decorators in template before 2.1 can obtain the correct types?

The answer is No. I thought it's a limitation of vue2 or whatever at the first time and ignore this inconvenience.

As for the "skipTemplateCodegen" option, I have tried it and turns out it brings more disadvantages.
e.g., I can no longer using cmd + mouseLeft in template to locate the defination of variables and functions.

This is what I want to know, If we just infer it as unknown, fixing it will become easier.

Seems like our opinions finally come up together, hope ur update as soon as posible. I have to use version 2.0.x for a while.
