using @DaveF indication, I get this working process.stdout.clearLine(); process.stdout.cursorTo(0); process.stdout.write("Downloading " + i + " bytes\r")

This didn't work for me. I used: process.stdout.clearLine(); process.stdout.cursorTo(0);. I'm not certain if using the carriage return is a hack, but clearLine() and cursorTo() are found within the node.js documentation

With ANSI escape codes as mentioned above, you can clear the line with .write("\x1b[0G\x1b[K");. Or without changing cursor position .write("\x1b[2K").

You could first write spaces, for instance you could write ''.padEnd(str.length) where str is your original string to overwrite, then do your hello.

This is great but how do you make it clear the contents of the line first? .write("goodbye\r") followed by .write("hi\r") results in hiodbye

To make the ansi escape code given above in a comment by @GarciadelCastillo to work in strict mode, replace the octal literal \033 with the hex literal \x1b like this: \x1b[0G. (that works with both strict and non-strict code)

For Windows, you can use the equivalent code '\033[0G', as in: process.stdout.write("Downloading " + data.length + " bytes\033[0G");
