ts-loader message is outputted when webpack is run with '--json'

[jumpinjackie]

When I run webpack --json and redirect its output to a json file, the following string is on the first line of the file, rendering it an invalid json file.

ts-loader: Using [email protected] and /path/to/tsconfig.json

You can turn it off with silent / log levels I believe

I have never had any ts-loader settings applied and circa v0.8.2 at least (this was the version I upgraded ts-loader from) that message never snuck to stdout when I ran webpack --json

You may also want to check out: logInfoToStdOut

Just ran across this as well. More normal in the UNIX world would be to log this kind of message to stderr. On my system (macOS) that message was on stdout, even without the logInfoToStdOut option. Would it be possible to change the default to stderr?

Hi @joerick - the details of how we landed where we are can be found here: #313

I'm open to change subject to the concerns raised in the linked issue still being addressed

[joerick]

Hm... so the default is for 'info' logs to go to stderr. Not sure why I was having that problem then. I've combed through the ts-loader code and I can't see any obvious reason why that would be. I'll let you know if I find anything definitive, otherwise, sorry for the noise!

No bother!
