AngularJS

-
AngularJs is a JavaScript-based open source front-end web application framework mainly maintained by Google. The JavaScript components complement Apache Cordova, the framework used for developing cross-platform mobile apps.

The AngularJS framework works by first reading the HTML page, which has embedded into it additional custom tag attributes. Angular interprets those attributes as directives to bind input or output parts of the page to a model that is represented by standard JavaScript variables. The values of retrieved from static or dynamic JSON resources.

AngularJS Exteds HTML with ng-directives.
The ng-app directive defines an AngularJS application.
The ng-model directive binds the value of HTML controls to application data.
The ng-bind directive binds application data to the HTML view.

AngularJS Expressions
           
AngularJS expressions are written inside double braces: {{ expression }}
AngularJS will “output” data exactly where the expression is written

Example:

<!DOCTYPE html>
<html>
<scriptsrc="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>

<div ng-app="">
  <p>expression: {{ 2+2 }}</p>
</div>

</body>
</html>

AngularJS Applications

AngularJS modules define AngularJS applications.
AngularJS controllers control AngularJS Napplications.
The ng-appp directive defines the application, the ng-controller directive defines the controller.

Double Submit Cookies Pattern

Image
Cross-Site Request Forgery (CSRF) Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they're currently authenticated. CSRF attacks specifically target state-changing requests, not theft of data, since the attacker has no way to see the response to the forged request. With a little help of social engineering (such as sending a link via email or chat), an attacker may trick the users of a web application into executing actions of the attacker's choosing. If the victim is a normal user, a successful CSRF attack can force the user to perform state changing requests like transferring funds, changing their email address, and so forth. If the victim is an administrative account, CSRF can compromise the entire web application. Cross-site Request Forgery(CSRF) protection via Double Submit Cookies Patterns. In this technique, we send a random value in both a cookie and as a request param...
