Code in server.js
var strava = require('node-strava-v3')
var express = require('express');
var app = express();
app.get('/', function(req, res){
strava.streams.activity({'id': 497191235, 'types':'distance'}, function(err, payload){
if(!err){
res.send(payload);
}
else{
res.send(err);
}
})
});
I would like to setup a view file (static HTML with a dynamic view) which gets its data via a controller file, which in turn retrieves it from the model (server.js) through app.get() call. I believe I would need to utilise $http.get() from the controller to access app.get()? The tutorials I read have provided a specifc path as the argument for $http.get(), but I don't think it applies to my situation.
Please advise - thank you.
[Edit] controller.js and index.html files at present:
//controller.js
var myApp = angular.module('myApp', []);
myApp.controller('AppCtrl', ['$scope', '$http',
function($scope, $http){
var refresh = function(){
$http.get('/').success(function(response){
$scope.contactlist = response;
});
};
refresh();
}]);
//index.html

I am new in angularjs tech. I have implemented one registration function in my project.
I have created one js file for routing and controller functionality in my project and its working fine, If i will do separate router and controller file then I am application is failing.
I need to do separate file for the router and controller.
Below is my code in one file.
app.js file
var app = angular.module('crasApp', [ 'ngRoute' ]);
app.config(function($routeProvider) {
$routeProvider.when("/", {
templateUrl : "./views/xyz.html",
controller : "searchCtrl"
}).when("/registration", {
templateUrl : "./views/abc.html",
controller : "MainCtrl"
}).when("/view", {
templateUrl : "./views/viewsdata.html",
controller : "overViewCtrl"
});
});
app
.controller(
"MainCtrl",
function($scope, $http) {
console.log("Hi");
});

Hi
</body>
<html>
So, Its working file if I am using one app.js file
I want to do seprate router and controller file.
router functionality i moved into different file and its working router functionality but not working controller functionality..
Separate router file as below.
router.js
var app = angular.module('crasApp', [ 'ngRoute']);
app.config(function($routeProvider) {
$routeProvider.when("/", {
templateUrl : "./views/retrieveTerminationReason.html",
/*controller : "searchCtrl"*/
}).when("/registration", {
templateUrl : "./views/registration.html",
/*controller : "MainCtrl"*/
}).when("/view", {
templateUrl : "./views/forbearanceRegistartionOverview.html",
/*controller : "overViewCtrl"*/
});
});
app.js as a controller
var app = angular.module('crasApp', []);
app
.controller(
'MainCtrl',
function($scope, $http) {
console.log("Hi");
});
Please any one can help on this part.
In router.js, change var app = angular.module('crasApp', [ 'ngRoute']) to var app = angular.module('crasApp').
Also, in app.js, your declaration should be: var app = angular.module('crasApp', ['ngRoute']);. Since you have a single module, 'crasApp', you must declare it's dependencies when you declare the module itself.
What you have currently is re-creating the module vs. appending functionality.
Also, be sure to include your router.js as well in your HTML .
the issue
when you're using var app = angular.module('crasApp', [ 'ngRoute']); in your route.js file you are initializing new module NOT adding config to existing module!
the best approach for structuring an Angular App is NOT using variable you can call your module in a different way like:
app.js
var MODULE_NAME = 'crasApp'
angular.module(MODULE_NAME, ['ngRoute']);
to create controller controllers.js
angular.module(MODULE_NAME).controller('MainCtrl',function($scope, $http) { //Note removing the dependencies array
console.log("Hi");
});
to create config routes.js
angular.module(MODULE_NAME).config(function($routeProvider) { //Note removing the dependencies array
$routeProvider.when("/", {
templateUrl : "./views/retrieveTerminationReason.html",
/*controller : "searchCtrl"*/
})
in your index.html
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular-route.min.js"></script>
<script src="js/app.js"></script>
<script src="js/routes.js"></script>
<script src="js/controllers.js"></script>
</head>
Note you don't need ng-controller directive in your HTML because defining it in routes is enough
separating services
create services.js for example
angular.module(MODULE_NAME).factory('Users',function($http,$q) {
return {
getUsers:function(){
var def = $q.defer();
$http({url:'URL_HERE',method:'GET'}).then(function(res){
def.resolve(res)
},function(err){
def.reject(err);
})
}
}
})
using in controller
angular.module(MODULE_NAME).controller('MainCtrl',function($scope, Users) { //Note Users is the name of the factory created above
Users.getUsers().then(function(res){
$scope.users=res;
},function(err){
$scope.error = err;
})
});
I'm having issue developing an application using expressjs and angular. I'm loading angular, bootstrap etc from my index page. to test, I put a button <a ui-sref=about>about</a> to go to about page. when I click the button from my index page, no problem. the page loads along with the libraries used in index.html and it console logs a message from AboutController. However, when I refresh the page http://localhost:3000/about, the page loads without loading the angular, bootstrap etc libraries. I know my <script> tags that load the those files are in index.html but I wonder if there is a way refresh the page from http://localhost:3000/about and load index first, then it would go to about or if my app could load the files in index on refresh making available the same files to about .
here is my file structure
Here is my code:
Index.html
<!DOCTYPE html>
<html lang="en" ng-app="myApp">
<head>
<meta charset="UTF-8">
<title>Title</title>
<base href="/">
</head>
<body>
<li><a ui-sref="about">About</a></li>
<li><a ui-sref="home">Home</a></li>

You need to change your server.js to make it renders the index.html.
app.get('/about', function (req,res) {
res.sendFile('index.html');
})
Once index.html is rendered ui-router will trigger the in-browser routing and display your about page correctly.
This world is sad to cry , am blocked for two hours with a problem that i couldnt define ,i can't retrieve data from my json file ,everything in my code seems correct.
This is my factory:
'use strict';
angular.module('starter.services')
.factory('userService',function ($http) {
return{
getUsers:function(){
return $http.get("http://localhost:26309/api/User/getAll/").then(function (response) {
return response.data;
});
}
}
});
and this controller :
'use strict';
angular.module('starter.controllers', ['starter.services'])
.controller('UsersCtrl', function($scope,userService) {
$scope.Users = [];
userService.getUsers().then(function (data) { $scope.Users= data.data; }); });
});

<div class = "list" >
<a class = "item" ng-repeat = "user in Users">
<h2>{{user.nom}}</h2>
</a>
</div>
</ion-view>
</body>
</html>
Thank you in advance
SOLUTION
i solved the problem by :
1- adding in the config.xml the permission <allow-navigation href="http://*/*"/>
2-installing cordova-plugin-whitelist ionic plugin add cordova-plugin-whitelist
3-add control-allow-origin extention to chrome :https://chrome.google.com/webstore/detail/allow-control-allow-origi/nlfbmbojpeacfghkpbjhddihlkkiljbi/related?hl=en-US
and finally : specifying the type of data returned by the back-end controller by adding this code to my Global.asax in Application_start method :config.Formatters.JsonFormatter.SerializerSettings.Formatting =
Newtonsoft.Json.Formatting.Indented;
config.Formatters.Remove(config.Formatters.XmlFormatter);
hope this helps someone
You don't want to resolve your $http call inside factory.
JS:
angular.module('app',[])
.controller('MainCtrl', function($scope, MyService){
var url = "http://jsonplaceholder.typicode.com/users";
MyService.getData(url).then(function(res){
console.log(res.data);
$scope.data = res.data;
});
})
.service('MyService', function($http){
return {
getData: function(url){
return $http.get(url);
}
}
})
HTML:
<!DOCTYPE html>
<html ng-app="app">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js"></script>
<script src="script.js"></script>
</head>
<body ng-controller="MainCtrl">
<ul>
<li ng-repeat="item in data">{{item.name}}</li>
</ul>
</body>
</html>
The issue is that you are resolving the promise in service with the value response.data, and again expecting the resolved value to have data property. Change your service code as below:
'use strict';
angular
.module('starter.services')
.factory('userService',function ($http) {
return {
getUsers: function(){
return $http.get("http://localhost:26309/api/User/getAll/").then(function (response) {
return response;
});
}
}
});
Or simply return the promise as below:
'use strict';
angular
.module('starter.services')
.factory('userService',function ($http) {
return {
getUsers: function(){
return $http.get("http://localhost:26309/api/User/getAll/");
}
}
});
I am trying to get user input through a text box using ng-model, and append to a base URL for a http.get call as follow;
index.html:
<html ng-app='vidRoute'>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Search Video</title>
<link rel="stylesheet" href="app/css/custom/main.css">
<link rel="stylesheet" href="app/css/custom/responsive.css">
</head>
<body>
<div id='mainwrapper'>
<div id='header' ng-controller="searchController">
<input type="text" id="searchTxt" ng-model="append">
Search Video
</div>
<div id="poster">
<div ng-view></div>
</div>
</div>

<script type="text/javascript" src="app/javascript/custom/vidRoute.js"></script>
</body>
</html>
searchcontroller.js
'use strict';
var vidcontrol = angular.module("vidcontrol", []);
vidcontrol.controller("vidcontroller", ['$scope', '$http', function($scope, $http) {
$http.get('http://api.themoviedb.org/3/tv/airing_today?api_key=d5e87524383e2872a9555990b268dc5b').success(function(response) {
$scope.results = response.results;
});
}]);
vidcontrol.controller('searchController', ['$scope', '$http',
function ($scope, $http) {
var url = "http://api.themoviedb.org/3/search/movie?api_key=d5e87524383e2872a9555990b268dc5b&query=";
// var searchTxt = $('#searchTxt').val();// this works fine when used
var searchUrl = url + append; //$scope.append also logs 'undefined' on the console
$http.get(searchUrl).success(function (response) {
$scope.searchResults = response.results;
});
}]);
but I'm not getting any response. when I log searchUrl on console, I could see that append was not updated according to value from text box. I'm quite new to Angular and I can't figure out what I'm doing wrong. What should I do to fix this?
Now, I see the issue. When controller loaded, it executes controller code. That mean REST query runs before view is built. That is reason you see undefined problem. Solution is to define a method in controller which will be invoked when you click "Search Video".
Update view
Search Video //Look at ng-click
Update Controller:
vidcontrol.controller('searchController', ['$scope', '$http',function($scope, $http) {
var url = "http://api.themoviedb.org/3/search/movie?api_key=d5e87524383e2872a9555990b268dc5b&query=";
$scope.search = function(){ // Look at here, Defined a method to invoke on "Search Video" link click
var searchUrl = url + $scope.append;
$http.get(searchUrl).success(function(response) {
$scope.searchResults = response.results;
});
};
} ]);
I have a quick question on loading external page with route. I am quite new to AngularJS.
var app = angular.module('app', []);
$routeProvider.when('/list', {
templateUrl: '/list.html'
})
Load up the page, but within the list.html there is controller defined.
list.html:
<script>
app.controller('test', function(){
console.log('test');
});
</script>
<div ng-controller="test">
</div>
The above code will throw me an error as test is undefined function, unless if i place the app.controller('test') to the parent page.
So i can't place controller on external .html files?

You have to create a separate script.js and should load in main html page during execution of main page or during click of the link
