Form validation with AngularJS
Client-side form validations are one of the coolest features inside of AngularJS. AngularJS form validation enables you to write a modern HTML5 form that is interactive and responsive from the start. There are many form validation directives available in AngularJS. We’ll talk about a few of the most popular ones here and then we’ll get into how to build your own validations. AngularJS makes it pretty easy for us to handle client-side form validations without adding a lot of extra effort. To use form validations, we first must ensure that the form has a name associated with it, like in the above example. All input fields can validate against some basic validations, like minimum length, maximum length, etc. It is usually a great idea to use the novalidate flag on the form element. Let’s look at all the validation options we have that we can place on an input field: Required To validate that a form input has been filled out, simply add the html5 tag: required to the input field: Minimum length

AngularJS Tutorial - AngularJS in 30 minutes
I started using AngularJS over 3 years ago when it was new and relatively unknown. Since then AngularJS has become one of the most popular JavaScript frameworks and for good reason. The AngularJS team have done superb work and are very dedicated to ensuring AngularJS is the best it can be. This AngularJS tutorial will be using version 1.3.4 and will cover just the basics and follow the best practices recommended by Google and by me through my own experience. To get started create a folder called angularjs-tutorial and create the following files copying the directory structure below. - angularjs-tutorial | - main.ctrl.js | - app.js | - index.html Open index.html and add the following simple HTML to create a basic web page that includes AngularJS and Twitter Bootstrap from a CDN. <! This HTML document also includes app.js and main.ctrl.js which you have just created. Within our app.js file we need to instantiate an AngularJS module which we will use for our app. angular.module('app', []); Info
Authentication in Single Page Applications with Angular.js - A Modest Proposal
9/2/2014 update:The GitHub repo now uses UI-router instead of the standard ngRoute routing module. This blog post will still illustrate the original technique utilizing ngRoute, while information regarding the UI-router approach can be found in the GitHub repo as well as this blogpost. The example app in the repo has been deployed to Heroku, so now you can test it out live for yourself right here. A separate blogpost discussing the complementing server-side code can be found here. I have been working a lot with Angular.js lately, and love how easy it makes it to create web applications with rich client-side functionality. It's an extremely useful asset in keeping your own client-side code lean, making it easy to separate business logic and declarative markup for anything view specific. How do I deal with authentication and authorization in single page applications? The server needs to communicate what permissions/role the client has on inital page load. Setting up client-side routing

AngularJS and Twitter Bootstrap playing nicely? | Will Vincent
It seems a large contingent of people have an inordinately difficult time getting AngularJS and Twitter Bootstrap to play nice together. Maybe I'm lucky, maybe I'm doing something right, or maybe I'm doing something wrong, but for me.. it just works. I'm still pretty new to Angular, so I won't presume to tell you how to do things. But having read about all the various struggles people have working with some of the Twitter Bootstrap UI pieces, drop downs, tabs, and modals for example, I guess I expected my mileage not to vary much. As it turns out, my mileage does vary. So, when I ran across this question External Links icon on stack overflow regarding getting modals to work without polluting the DOM with excessive instances of the modal markup, I decided I'd share my experience and approach. Any AngularJS gurus who may stumble across this, please be gentle if I'm way off here -- remember, I'm still a noob :)
