How can I pretty-print JSON using node.js?

Question

This seems like a solved problem but I am unable to find a solution for it.

Basically, I read a JSON file, change a key, and write back the new JSON to the same file

If you don't want to store this anywhere, but just view the object for debugging purposes.

console.log(JSON.stringify(object, null, "  "));

You can change the third parameter to adjust the indentation.
