Get Node.js Command Line Arguments with yargs
Using command line arguments within Node.js apps is par for the course, especially when you're like me and you use JavaScript to code tasks (instead of bash scripts). Node.js provides process.argv but that doesn't provide a key: value object like you'd expect:
/*
$ node myscript.js --key1=value1 --key2=value2
[ 'node',
'/path/to/myscript.js',
'--key1=value1',
'--key2=value2' ]
*/
Bleh. If you want to work with a sane API for command line arguments, use yargs:
// Get the yargs resource
var yargs = require('yargs').argv;
// Check for arguments
if(yargs.someKey === expectedValue) {
// Do whatever
}
/*
yargs = {
key1: value1
key2: value2
};
*/
yargs provides a key:value object for arguments instead of the native process.argv mess. No hassle, no fuss, just access to command line arguments with a logical API. Happy noding!

Feature detection via JavaScript is a client side best practice and for all the right reasons, but unfortunately that same functionality hasn't been available within CSS. What we end up doing is repeating the same properties multiple times with each browser prefix. Yuck. Another thing we...

Keeping equal heights between elements within the same container can be hugely important for the sake of a pretty page. Unfortunately sometimes keeping columns the same height can't be done with CSS -- you need a little help from your JavaScript friends. Well...now you're...
![Pure CSS Slide Up and Slide Down]()
If I can avoid using JavaScript for element animations, I'm incredibly happy and driven to do so. They're more efficient, don't require a JavaScript framework to manage steps, and they're more elegant. One effect that is difficult to nail down with pure CSS is sliding up...
