Node.js Alert Causes Crash

gtmtg picture gtmtg · Jul 23, 2012 · Viewed 49.7k times · Source

I'm trying to create a node.js app and

alert('Sample Alert');

is causing my program to crash. Node says

ReferenceError: alert is not defined

and then quits. I can use the alert function when running javascript on a regular html page, so I'm at a loss to understand why this is... Is this a separate module that I have to use with node.js?

The alert() function is a property of browser window objects. It is not really part of JavaScript; it's just a facility available to JavaScript code in that environment.

Try console.log("Hello World");
