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.
![JavaScript Promise API]()
While synchronous code is easier to follow and debug, async is generally better for performance and flexibility. Why "hold up the show" when you can trigger numerous requests at once and then handle them when each is ready? Promises are becoming a big part of the JavaScript world...
![Detect DOM Node Insertions with JavaScript and CSS Animations]()
I work with an awesome cast of developers at Mozilla, and one of them in Daniel Buchner. Daniel's shared with me an awesome strategy for detecting when nodes have been injected into a parent node without using the deprecated DOM Events API.
![CSS Filters]()
CSS filter support recently landed within WebKit nightlies. CSS filters provide a method for modifying the rendering of a basic DOM element, image, or video. CSS filters allow for blurring, warping, and modifying the color intensity of elements. Let's have...
![Multiple Backgrounds with CSS]()
Anyone that's been in the web development industry for 5+ years knows that there are certain features that we should have had several years ago. One of those features is the HTML5 placeholder; we used JavaScript shims for a decade before placeholder came...
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!
