title: Angular2- few questions related to data saving in a static web page
body: <p>Im coding a static page app using Angular, which shows various Instagram and Twitter posts of the company, and shows the details of the members. I have few questions regarding this, and would like any help.
  Firstly, I have about 100+ contacts to display on the first page. Should I create a Json by myself and retrieve it from the service, or should I create a backend and save it there ? I do not have any backend as of now.
  Other thing, I was able to retrieve Instagram Json with media content using their API, the doubt im facing is, once I have the call done, will the Json change automatically when the user adds/edits their posts? Or will the Json be the same as I first called it with? Any help is appreciated. Thanks.</p>
