Not sure what the issue has to do with IDEA - it comes from visionmedia where this property is deprecated and is going to be removed.

Not sure what they mean saying that IDEA doesn't support colors on stderr... Actually stderr output is colored according to 'Error output' preferences (Preferences | Editor | Colors & Fonts | Console Colors, Console).

May be, the actual issue is that Node.js console in IDEA is non-tty, as node process is started with input/output streams redirection (https://youtrack.jetbrains.com/issue/WEB-1933).


The visionmedia debug module correctly reports a deprecation warning whenever process.env.DEBUG_FD is used. The reason this is an IDEA issue is because WebStorm sets the deprecated DEBUG_FD environment variable before running a NodeJS configuration.

Expect a lot of traffic on this because the warning comes from the debug module, a dependency of the connect module, a dependency of the express module. Everyone running an express app will see this deprecation warning when running within WebStorm, and not when running outside of WebStorm.


I've just opened a PR to fix that issue with debug package. hoping maintainers accept that :))
