console.error enhancement #4452
Description
I'm not sure exactly how this works and if this is the right place to raise the issue but:
In the browser (chrome)
console.error(new Error);
// Logs the error and an expandable stack trace.
Error(…)
(anonymous function) @ VM297:2
InjectedScript._evaluateOn @VM174:878
InjectedScript._evaluateAndWrap @ VM174:811
InjectedScript.evaluate @ VM174:667In node:
console.error(new Error)
[Error]
// To properly show the stack trace I would have to console.error the stack.
// In the browser this causes the stack to be visible twice.
console.error((new Error).stack)Is it possible to make it so that node will automatically add stack traces on console.error?

I like this suggestion

This will impact behaviour of
console.warnas well since in the browser, even that prints the stack trace.Also, so does
console.login chrome/firefox/etc.So, from what I gather, it's the way
util.formathandlesErrorobjects that needs to change.evanlucas commentedon Jan 8, 2016
I always forget to add the check for
err.stack || errand it drives me nuts. I would be +1 on this, but it would be a semver-major change.targos commentedon Jan 8, 2016
I would also like this, but on the other hand I'm sure there are a lot of libraries out there that use
console.errorto output text tostderr(I often do it myself in my utility scripts) so it would definitely be semver-major.evanlucas commentedon Jan 8, 2016
Yea I think it should be a change to util.inspect though for Errors. I think that would make the change less breaking to the ecosystem (although still a major change)

I agree that the change should be in
util.inspect. The way Errors are displayed could be changed informatError.Edit: I can pick this up and make the changes in
formatErrorif someone hasn't already picked this up.Edit 2: Had some time so got it done.

Certainly
util.inspectis the right place. +1 this change for the next major version.util: Change how Error objects are formatted
