Show Images in Console with Node.js console-png
Introducing colors into the command line makes console reading much easier which is why finding Chalk was a life-changing event for me. I started digging deeper into making the console more graphical and I found another module that could bring the console to life: console-png!
The JavaScript
Assuming you've installed console-png or grabbed it from GitHub, it doesn't take much to output an image to the console:
// Attach module to the console
require('console-png').attachTo(console);
// Read the image, let console-png output it to console
console.png(require('fs').readFileSync(__dirname + '/logo.png'));
As for the use case of such a module, there probably aren't a ton. It would be useful to show a command line splash screen when an app starts up, and it may be useful as a feedback mechanism as the user follows app flow.

![Detect Vendor Prefix with JavaScript]()
Regardless of our position on vendor prefixes, we have to live with them and occasionally use them to make things work. These prefixes can be used in two formats: the CSS format (-moz-, as in -moz-element) and the JS format (navigator.mozApps). The awesome X-Tag project has...
After your article on promises, I’m sad this is using callbacks!
Agreed (I didn’t create it). But they could add https://davidwalsh.name/promises-callbacks-promisifynode !
Instead of joining the dirname and filename with string concatenation, you should use the node path joiner so it will work on windows too :)
I like where this is going!
