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.

Image reflection is a great way to subtly spice up an image. The first method of creating these reflections was baking them right into the images themselves. Within the past few years, we've introduced JavaScript strategies and CANVAS alternatives to achieve image reflections without...

I've said it over and over but I'll say it again: JavaScript's main role in web applications is to enhance otherwise boring, static functionality provided by the browser. One perfect example of this is the Javascript/AJAX-powered star rating systems that have become popular over the...
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!
