Make an AngularJS directive to remotely validate an email field in a form. This example can also be applied to remotely validate any field in a form.
I’ve recently been dabbling on Node.js and it’s been a really awesome server platform. So naturally, I've needed to use Express.js for scripting. This also means that I’ve been dealing with parameters and query strings. They’re very important if you’re a server-side developer no matter which scripting language you use. They help accomplish many things like web service API’s. Although these are common and straightforward for server-side development, I’d like to share my understanding of them.
