Node.js: printing to console without a trailing newline?

Question

Is there a method for printing to the console without a trailing newline? The console object documentation doesn't say anything regarding that:

console.log()

Prints to stdout with newline. This function can take multiple arguments in a printf()-like way. Example:

console.log('count: %d', count); 

If formating elements are not found in the first string then util.inspect is used on each argument.

Answer 1

You can use process.stdout.write():

process.stdout.write("hello: "); 

See the docs for details.

Answer 2

Also, if you want to overwrite messages in the same line, for instance in a countdown, you could add \r at the end of the string.

process.stdout.write("Downloading " + data.length + " bytes\r");
