You can install two plugins in WordPress that will give you AngulaJS functionality in your website. Warning: The plugins may not give you the results you would expect for all of the AngularJS commands. I found that I was unable to use ng-init. The first one is call “AngularJS for WordPress” by Roy Sivan. When you install this you also need to install another plugin called “WP REST API” by WP REST API Team.
