In this Plunk I've created a $http .get service and
used api.GitHub.com to retrieve the data of a GitHub user

(function() {

  var github = function($http) {

    var getUser = function(username) {
      return $http.get("https://api.github.com/users/" + username)
        .then(function(response) {
          return response.data;
        });
    };

    var getRepos = function(userinfo) {
      return $http.get(userinfo.repos_url)
        .then(function(response) {
          return response.data;
        });
    };
    var getAllUser = function() {
      return $http.get("https://api.github.com/users?since=135") //you can find these user at "https://api.github.com/users" adddress
        .then(function(response) {
          return response.data;
        });
    };
    return {
      getUser: getUser,
      getRepos: getRepos,
      getAllUser: getAllUser
    };
  };
  var module = angular.module("githubViewer");
  module.factory("github", github);
}());

<div id="userDetails">
  User Name: {{userinfo.name}}, Loacation: {{userinfo.location}}
  <br>
  <img ng-src="{{userinfo.avatar_url}}" title="{{userinfo.name}}" style="height:90px;width:90px;"> Order Repository By:
