Installation

1. Install the component using npm
2. angular2-cookie-law depends on the Angular animations module in order to be able to do more advanced transitions. If you want these animations to work in your app, you have to install the @angular/animations module and include the BrowserAnimationsModule in your app.

# To get the latest stable version and update package.json file: 
$ npm install angular2-cookie-law@6 @angular/animations --save

or yarn with:

$ yarn add angular2-cookie-law @angular/animations
