How to ignore console.error and still use js_errors: true

vemv opened this issue 7 years ago · comments

Hi!

Let's say a JS library outside of my control likes to console.error on warnings. They don't break my app in any way.

In that case, the js_errors: true option would cause my build to fail. So I have to set it to false, which is quite undesirable.

Is there a way to observe only actual errors, disregarding console.error output?

Cheers - Victor

Nope, ask the library to stop outputting non-errors to console.error or check if the library has a production mode that doesn't output non-errors to console.error

Alright, mind to clarify why is this not possible? Phantomjs thing or poltergeist implementation detail?

Poltergeist relies on the PhantomJS onError callback which is called when console.error is called - The name console.error is pretty self explanatory, not sure why "some" libraries choose to use it for warnings.
