Angular Consent

Easily show consent messages that keep appearing until the user clicks them away.

Useful if you need to show legal disclaimers (e.g. to conform to the EU Cookie Consent law).

• very lightweight (~1KB)
• use your own markup and CSS to make the messages fit perfectly in your application
• supports multiple consent messages on the same page

Try online demo.

Requirements:

• ngCookies

Quick example

<!-- add consent attribute to any element -->
<!-- to expose $consent controller to children -->
<section consent>

  <!-- then use your own custom markup to create the message -->
  <section ng-if="$consent.hasNotAgreedYet()">
    <p>This web application uses cookies to store private data.</p>
    <button ng-click="$consent.agree();">Agree</button>
  </section>
  
</section>

Usage

First install the module using bower:

$ bower install angular-cookies
$ bower install angular-consent

and add the library to your application:

<script src="angular-cookies.min.js"></script>
<script src="angular-consent.min.js"></script>

Then add the ngCookies and angularConsent modules to the dependencies of your AngularJS application module:

angular.module('yourApp', ['ngCookies', 'angularConsent']);

Now you can use the consent directive anywhere in your markup:

<!-- add consent attribute to any element -->
<!-- to expose $consent controller to children -->
<section consent>

  <!-- then use your own custom markup to create the message -->
  <section ng-if="$consent.hasNotAgreedYet()">
    <p>This web application uses cookies to store private data.</p>
    <button ng-click="$consent.agree();">Agree</button>
  </section>
  
</section>

To create multiple consents in a single application, pass a unique key to the consent attribute:

<!-- consent for cookie disclaimer -->
<section consent="cookie-disclaimer">
  <section ng-if="$consent.hasNotAgreedYet()">
    <p>This website uses cookies.</p>
    <button ng-click="$consent.agree();">Ok, I understand</button>
  </section>
</section>

<!-- consent for privacy disclaimer -->
<section consent="privacy-disclaimer">
  <section ng-if="$consent.hasNotAgreedYet()">
    <p>This website stores private data.</p>
    <button ng-click="$consent.agree();">Ok, I understand</button>
  </section>
</section>

You can also re-use a consent across your page or application:

<!-- display consent message in header -->
<header consent="cookie-disclaimer">
  <section ng-if="$consent.hasNotAgreedYet()">
    <p>This website uses cookies.</p>
  </section>
</header>

<!-- and show the button in the footer -->
<footer consent="cookie-disclaimer">
  <button ng-click="$consent.agree();">Ok, I understand</button>
</footer>

By default cookies are stored for 360 days, but you can customize cookie options on a consent level:

<!-- expirationDate should be string string of form 'Wdy, DD Mon YYYY HH:MM:SS GMT' -->
<header consent="cookie-disclaimer" consent-cookie-options="{ expires: expirationDate }">
  <section ng-if="$consent.hasNotAgreedYet()">
    <p>This website uses cookies. The cookie will be stored until expiration date.</p>
  </section>
</header>
