The AngularJS refers to a structural framework which has been mainly designed for dynamic web applications. This framework lets you use the HTML text as template language. It is convenient and useful because you will not need to write too many codes for this. When you deploy a client-side AngularJS app you do not need Node.JS to work. You may get it from Google CDN even in the absence of the script hosted on the server. Node.JS is primarily used for testing purposes; while it is advantageous if you have it, it is not essential for hosting an AngularJS app. You can easily host the application on your server without the Node.JS and even test it locally. Almost any server online can host an AngularJS app since the work is entirely handled by the client side. To host an AngularJS app on your server, you must find one which supports and is also compatible with Angular apps. Since AngularJS is essentially a front-end framework, it will automatically require a back-end.
