react: Error line number in Error Boundary

Hey,

As I can not reopen issue #13790, I opened this.

If you don’t like to fix/add my request, simply say won't fox, but don’t close the issue with simple/not related answer, as @aweary did. React is pro library, you are pro, so act like pros.

Thanks.

@gaearon any update? do you need more info?

I believe it fetches a sourcemap and then finds the information in it. I don’t see us including a sourcemap parser into React itself, and definitely not in production.

Do you want this in development or in production?

I think in general, the browsers are best-positioned to fix this by providing a stack trace with sourcemaps applied. I don’t know if there is an existing proposal for this.

@dehghani-mehdi this information is only available when providing a sourcemap to the browser via your compiler (I assume webpack). You will not be able to access this information on a production site, as no sourcemap is provided when compiling for production.
