I'm new to AngularJs and am stuck on a tutorial in the Routing section: https://thinkster.io/tutorials/mean-stack/routing-views-with-angular
Error Message:
Uncaught Error: [$injector:modulerr] Failed to instantiate module flapperNews due to:
Error: [$injector:nomod] Module 'flapperNews' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
Prior to this error message I had a later version of angularjs (1.5.7) and it gave me this error - someone suggested online that you change the version. I had this error then:
Uncaught Error: [$injector:modulerr]
Please help me so that I can move on and get back to learning.
Here are my files:

THanks!
Top of my files seem to have gotten cut off but I don't have time to fix it ATM. Sorry
Your Javascript code encapsulated between
(function (){
...
})
needs to be executed in order to load the code inside. For that, You can add (); at the end
(function (){
...
})();
Your app.js is malformed.
Try this
angular.module('flapperNews', ['ui.router'])
.config([
'$stateProvider',
'$urlRouterProvider',
function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('home', {
url: '/home',
templateUrl: '/home.html',
controller: 'MainCtrl'
});
$urlRouterProvider.otherwise('home');
}
])
.factory('posts', [function(){
// service body
var obj = {
posts: []
};
return obj;
}])
.controller('MainCtrl',[
'$scope',
'posts',
function($scope, posts){
$scope.test = 'Reddit Emulator';
$scope.posts = posts.posts
$scope.addPost = function(){
if ($scope.title === '' || $scope.title == null)
$scope.title = 'post ' + (count + 1);
$scope.posts.push({
title: $scope.title,
link: $scope.link,
upvotes: getRandomInt(0,25)
});
$scope.posts = posts.posts
$scope.title = '';
$scope.link = '';
};
$scope.incrementUpvotes = function(post) {
post.upvotes += 1;
};
$scope.decrementUpvotes = function(post) {
post.upvotes -= 1;
};
}]);
Then put the getRandomInt function inside the controller.

I have a pretty simple custom directive which presents a form to enter a numeric value. This directive is embedded inside a modal dialog box that is triggered when required. While I can pass data into the dialog through the modal, I am having trouble getting data entered in the input element within the directive back out when the user clicks "OK". I imagine it has something to do with the scope of the directive, since I am using isolate scope, but I marked the name with '=' in the scope section, so I'm not sure what is going wrong.
Here is the plunker that demonstates the issue. Plunker example
var app = angular.module('plunker', ['ngAnimate', 'ngSanitize', 'ui.bootstrap']);
app.controller('MainCtrl', function($scope, $uibModal, $log, $document) {
var self = this;
var $ctrl = self;
$ctrl.modalresult = "no result";
$ctrl.name = 'World';
$ctrl.myvalue = "-99";
$ctrl.openGetConstantDialog = function(varname, parentSelector, size) {
var parentElem = parentSelector ?
angular.element($document[0].querySelector(parentSelector)) : undefined;
$ctrl.modalInstance = $uibModal.open({
animation: $ctrl.animationsEnabled,
template: `<get-numeric-dialog title="Define a New Constant"
prompt="Enter a value for constant"
varname="${varname}" placeholder="Enter a numeric value">
</get-numeric-dialog>
<div class="modal-footer">
<button class="btn btn-primary" type="button" ng-click="$ctrl.ok(myvalue)">OK</button>
<button class="btn btn-warning" type="button" ng-click="$ctrl.cancel()">Cancel</button>
</div>`,
controller: 'ModalInstanceCtrl',
controllerAs: '$ctrl',
size: 'sm',
appendTo: parentElem
});
$ctrl.modalInstance.result.then(function(value) {
$ctrl.modalresult = $ctrl.myvalue;
console.log("modal instance returned value: ", $ctrl.myvalue);
},
function() {
$ctrl.modalresult = "no value returned"
}
);
}
});
app.controller('ModalInstanceCtrl', function($uibModalInstance, $scope) {
var $ctrl = this;
$ctrl.value = undefined;
$ctrl.ok = function() {
$uibModalInstance.close($ctrl.newValue);
};
$ctrl.cancel = function() {
$uibModalInstance.dismiss('cancel');
};
});
app.directive('getNumericDialog', [function() {
return {
templateUrl: 'get_numeric_dialog.html',
restrict: 'E',
scope: {
title: '#',
prompt: '#',
varname: '#',
placeholder: '#',
myvalue: '='
}
};
}]);
Here's the directive template:
<div class="modal-header">
<h5 class="modal-title" id="modal-title">{{title}}</h5>
</div>
<div class="modal-body" id="modal-body">
<p>{{prompt}} '<span class="bold">{{varname}}</span>'</p>
<input type='text' placeholder='{{placeholder}}' ng-model="value"><br>
</div>
I managed to get this working after a couple of days, not quite structured as above, because an embedded directive ultimately wasn't worth the additional complexity, but in case anybody else is having trouble, solution below.
var app = angular.module('plunker', ['ngAnimate', 'ngSanitize', 'ui.bootstrap']);
app.controller('MainCtrl', function($scope, $uibModal, $log, $document) {
var self = this;
var $ctrl = self;
$scope.modalresult = "no result";
$scope.openModal = function() {
var getConstantTemplate = function(title, prompt, buttonCaption, varName) {
let template = `<div class="modal-header">
<h5 class="modal-title" id="modal-title">${title}</h5>
</div>
<div class="modal-body" id="modal-body">
<p>Value for constant '<span class="bold">${varName}</span>':</p>
<input type='text' varname="weeks" placeholder='Enter a number' ng-model="$ctrl.newValue">
<br>
</div>
<div class = "modal-footer" id="modal-footer">
<button class="btn btn-primary" type="button" ng-click="$ctrl.ok()">${buttonCaption}</button>
<button class="btn btn-warning" type="button" ng-click="$ctrl.cancel()">Cancel</button>
</div>`
return template;
}
var modalInstance = $uibModal.open({
animation: true,
template: getConstantTemplate("New Constant", "a", "Save", "months"),
controller: 'ModalInstanceCtrl',
controllerAs: '$ctrl',
size: 'sm'
});
modalInstance.result.then(function(result) {
console.log('modalInstance got result ' + result);
$scope.modalresult = result;
});
};
});
app.controller('ModalInstanceCtrl', function($scope, $uibModalInstance) {
var $ctrl = this;
$ctrl.prompt = "Enter a value for constant ";
$ctrl.varname = "weeks";
$ctrl.placeholder = "Enter a number";
$ctrl.ok = function() {
console.log("OK has been called with newValue " + $ctrl.newValue);
$uibModalInstance.close($ctrl.newValue);
};
$ctrl.cancel = function() {
console.log("Cancel has been called");
$uibModalInstance.close("model closed cancelled");
};
})

I am trying to access an http get response called during route change using ui route. The resolve itself happens but i am unable to access the response. I have tried some approaches in "listcontroller" which is shown. I am using a sample httpget url found in the internet for test. Angular version: v1.2.32. ui-route: 1.0.15.
script.js
var app = angular.module("Rasp", ["ui.router"])
.config(['$stateProvider', '$urlRouterProvider',function ($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise("/home");
$stateProvider
.state("ipList", {
url: "/ipList",
templateUrl: "templates/list.html",
controller: "listController",
resolve: {
SensorIP : function($http){
$http.get('https://httpbin.org/ip')
.then(function(response){
console.log('res');
console.log(response);
return response.data.origin;
});
}
}
})
.state("home", {
url: "/home",
templateUrl: "templates/home.html",
controller: "homeController"
});
}])
.controller("RaspController", ['$scope', '$http', function ($scope, $http) {
$scope.getDetails = function () {
// $http.get('https://httpbin.org/ip')
// .then(function (response) {
// console.log(response);
// $scope.response = response;
// },
// function (error) { console.log(error); }
// );
// };
}])
.controller("homeController", ['$scope', function ($scope) {
}])
.controller("listController", ['$scope','SensorIP',function ($scope,SensorIP) {
$scope.sensorList = SensorIP;
var vm = this;
this.list1 = SensorIP;
var logfunc = function() {console.log($scope.sensorlist)};

I would like to add link with controller to route but controller does not work.
I get this:
{{title}}
{{shortTitle}}
{{text}}
If I will put controller only to html also does not work
but when I added script to main controller in Default.html controller working correct
Where I made mistake?
#SSH this not work
$stateProvider
.state('home', {
url: '/',
template: '<div data-ng-include="'Scripts/js_angular_project/website/home/homePage.html'"></div>',
controller: 'homeCtrl'
})
homePage.html
<div>
<h2>{{title}}</h2>
<h3>{{shortTitle}}</h3>
<p>{{text}}</p>
</div>
<script>
app.controller('homeCtrl', function ($scope) {
$scope.title = "Volvo";
$scope.shortTitle = "Volvo";
$scope.text = "example";
});
</script>
#SSH this also does not work
$stateProvider
.state('home', {
url: '/',
templateURL: '/Scripts/js_angular_project/website/home/homePage.html',
controller: 'homeCtrl'
})
homePage.HTML - I remove ng-controller
<div>
<h2>{{title}}</h2>
<h3>{{shortTitle}}</h3>
<p>{{text}}</p>
</div>
<script>
app.controller('homeCtrl', function ($scope) {
$scope.title = "Volvo";
$scope.shortTitle = "Volvo";
$scope.text = "example";
});

you should put controller name in router and also remove ng-controller = "homeCtrl" from template.
state('home' ,{
url : '/',
templateUrl:'/yourTempalteAddress',
controller:'homeCtrl'
})
and define your app in controller.
var app = angular.module("yourApp",[]);
app.controller('homeCtrl', function ($scope) {
$scope.title = "Volvo";
$scope.shortTitle = "Volvo";
$scope.text = "example";
});
I began following a tutorial to AngularJs today, but implementing something slightly different, now I'm stuck, seems that Angular is not recognizing the inline template "home".
P.S: To run this locally on chrome I had to install a webserver.
angular.module('little_tweet', ['ui.router'])
.config(['$stateProvider', '$urlRouterProvider', function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('home', {
url: '/home',
templateUrl: '/home.html',
controller: 'MainCtrl'
})
.state('posts', {
url: '/posts/{id}',
templateUrl: '/posts.html',
controller: 'PostsCtrl'
});
$urlRouterProvider.otherwise('home');
}])
.factory('posts', [function() {
var o = { posts: []};
return o;
}])
.controller('MainCtrl', ['$scope', 'posts', function($scope, posts){
$scope.posts = posts.posts;
$scope.current_user = 'me';
$scope.addPost = function() {
if(!$scope.message || $scope.message === '') { return; }
$scope.posts.push({
user: $scope.current_user,
message: $scope.message,
time: new Date()
});
$scope.message = '';
};
}])
.controller('PostsCtrl', ['$scope', '$stateParams', 'posts', function($scope, $stateParams, posts) {
$scope.post = posts.posts[$stateParams.id];
}]);

Remove the / from template url in routes.
EDIT
there is an extra { in {{{post.user}}: {{post.message}} at {{post.time}}.
