Question

I’ve noticed strange behavior when trying to redirect the output form a node.js script in Windows. The smallest reproducible example of this behavior is as follows:

From the Windows console (cmd.exe):

c:\> node -e console.log('hello')
hello

From Powershell:

PS C:\> node -e console.log('hello')
PS C:\> 

That is to say, it exits without writing anything to the console.

This is a problem because when I try to redirect the output to a file, nothing is written, eg

node -e console.log(123) > temp.txt

is creating an empty file named temp.txt.

Is there something about how node is writing console.out to stdio?

Answer 1

It seems that the problem is in the parenthesis.

Try this:

node -e "console.log('hello')"

As for the redirection, there is imho ne reason why this should not work. You may also try to pipe it to Out-File temp.txt.
