Console.dir - Nodejs redirect to a file

Question

How can i redirect the console.dir(obj) output to a file instead of the console? I considered overwriting console.dir (with my custom fn.)to use file stream instead of stdout stream but the logic to walk down the object tree scares me.

Note: My node process is launched indirectly by emacs editor, so i cant use pipe to redirect any output.

i have said, i cant access stdout as my node process is a child process of emacs process — , Jan 07 '15 at 01:03

overwriting console.log is doable as what goes in as an arg, comes out... console.dir is not the same... — , Jan 07 '15 at 01:11

console.dir is just a wrapper around util.inspect that uses its default arguments.

console.log(util.inspect(myObj));

So you could simply do

var fs = require('fs');
function logToFile(input){
    fs.writeFile('.log', util.inspect(input));
}

had to use `fs.writeFileSync` with those arguments, but works great! – JL Peyret Aug 03 '22 at 19:29
