How wide is the node.js console?

Question

How wide is the node.js console?

In node.js, how do I get the current width of the console window and/or buffer?

The analog in .net is Console.BufferWidth and/or Console.WindowWidth.

I want to exercise more control over my line wrapping.

node.js
console

Answer 1

Looks like the current best way is this property:

process.stdout.columns

And for height (rows):

process.stdout.rows

Also note that there is a "resize" event, which might come in handy:

process.stdout.on('resize', function() {
  console.log('screen size has changed!');
  console.log(process.stdout.columns + 'x' + process.stdout.rows);
});

Answer 2

if (process.stdout.isTTY) {
  console.log("The console size is:", process.stdout.getWindowSize());
} else {
  console.log("stdout is not a console");
}
