I'm trying to inject my factory into a controller. If I list the factory as one of the controller's parameters, I get this error:
Error: [$injector:unpr] Unknown provider: wordRushFacProvider <- wordRushFac <- wordrushCtrl
http://errors.angularjs.org/1.6.1/$injector/unpr?p0=wordRushFacProvider%20%3C-%20wordRushFac%20%3C-%20wordrushCtrl
Here is the code for my factory:
(function() {
"use strict";
angular
.module("wordrush")
.factory("wordRushFac", function($http) {
function getValidWords() {
return $http.get('../data/valid-words.txt');
}
return {
getValidWords : getValidWords
}
})
})
And the code for my controller:
(function() {
'use strict'
angular
.module('wordrush')
.controller('wordrushCtrl', function($scope, $http, wordRushFac) {
wordRushFac.getValidWords().then(function(words) {
$scope.words = words.data;
});
$scope.words = 'Hello'
});
})();
And for my index.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Word Rush</title>
<link rel="stylesheet" href="node_modules/angular-material/angular-material.css">
<link rel="stylesheet" type="text/css" href="css/style.css">

<script src="scripts/app.js"></script>
<script src="components/wordrush.ctr.js"></script>
<script src="components/wordrush.fac.js"></script>
</head>
<body ng-app="wordrush" ng-controller="wordrushCtrl">
<h1> {{ words }} </h1>
</body>
</html>
And for my app.js:
angular
.module('wordrush', ['ngMaterial'])
.config(function($mdThemingProvider) {
$mdThemingProvider.theme('default')
.primaryPalette('blue')
.accentPalette('green');
})
I made a program with code identical to this except the names and variables were changed, and it worked fine. So what am I doing wrong here?
Here is a plunkr that says "Hello": https://plnkr.co/edit/MyxcXQ8YI4QYqeFsyVJz?p=preview
You have an extra set of open / close parenthesis in your controller definition, remove those:
angular
.module('wordrush')
.controller('wordrushCtrl', function($scope, $http, wordRushFac) {
wordRushFac.getValidWords().then(function(words) {
$scope.words = words.data;
});
$scope.words = 'Hello'
});
Also, are you sure you are including the ng-material JS file? I didn't see that listed in your HTML.
You're not injecting in the controller, should be:
.controller('wordrushCtrl', ['$scope', '$http', 'wordRushFac', function($scope, $http, wordRushFac) {
// Rest of controller code;
}]);
Switch your scripts. Factory script should be first then controller
Ther order should be,
<script src="scripts/app.js"></script>
<script src="components/wordrush.fac.js"></script>
<script src="components/wordrush.ctr.js"></script>
DEMO
I made the following changes and it worked fine.
(function() {
"use strict";
angular
.module("wordrush")
.factory("wordRushFac", function($http) {
function getValidWords() {
return $http.get('../data/valid-words.txt');
};
return {
getValidWords : getValidWords
};
});
}());
I am trying to set a header value based on the value in my controller. I have the header sending when I am hard coding it as shown below but how can I pass the value from the controller into the ngResource get request,
eg I want the value of anything in the headers to be the value from my controller.
var app = angular.module('app', ['ngResource']);
app.factory('UserService', function ($resource) {
return $resource('http://jsonplaceholder.typicode.com/users/:user',{user: "#user"},{
get: {
method: 'GET',
headers: { 'something': 'anything' }
}
});
});
app.controller('TestCtrl', function($scope, $resource, UserService) {
$scope.test = "text";
UserService.get({
user: 2
}, function(data) {
$scope.id = data.id;
}, function(err) {
console.log(err);
});
});

I have a problem I have this piece of code:
index.html:

}
}])
loginService.js
app.factory('loginService', ['', function(){
return function login(){
};
}])
So, I get this error:
Error: $injector:unpr Unknown Provider
The error page on the AngularJS docs says:
This error results from the $injector being unable to resolve a
required dependency. To fix this, make sure the dependency is defined
and spelled correctly
Well, I`m sure is spelled correctly and it should be defined. I have already tried to put a getter in the loginServices.js to get the tradePlace module and also tried to use a getter with the tradePlaceCntrls module but I still get the error.
I don`t know how to fix this.
Not sure if this is it but have you tried defining your factory like this?
app.factory('loginService', function(){
return function login(){
};
});
You don't need the array as your login service doesn't have any dependencies. That '' might be causing your issue. Try removing the array as it is not necessary in this case.
Also, you could define your login service as a service:
app.service('loginService', function(){
return function login(){
};
});
I'm trying to build my own service by following the example in the documentation for the factory methodology. I think I've done something wrong however because I continue to get the unknown provider error. This is my code for my app including the declaration, configuration and factory definition.
EDIT
I've now added all of the files to help troubleshoot
EDIT
The full details of the error are below the issues appears to be with getSettings, as it's looking for getSettingsProvider and cannot find it

These are all of the files I have in my app currently
app.JS
//Initialize angular module include route dependencies
var app = angular.module("selfservice", ['ngRoute']);
app.config(function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl:"partials/login.html",
controller:"login"
});
});
app.factory('getSettings', ['$http', '$q', function($http, $q) {
return function (type) {
var q = $q.defer();
$http.get('models/settings.json').success(function (data) {
q.resolve(function() {
var settings = jQuery.parseJSON(data);
return settings[type];
});
});
return q.promise;
};
}]);
And here is how I am using this service in my controller
controller.JS
app.controller("globalControl", ['$scope','getSettings', function ($scope,getSettings) {
var loadSettings = getSettings('global');
loadSettings.then(function(val) {
$scope.settings = val;
});
}]);
app.controller("login", ['$scope', function ($scope) {
return ""
}]);
directives.js
app.directive('watchResize', function(){
return {
restrict: 'M',
link: function(scope, elem, attr) {
scope.spacer = (window.innerWidth < 1025) ? '' : 'large-3';
scope.button = (window.innerWidth < 1025) ? '' : 'large-6';
angular.element(window).on('resize', function(){
scope.$apply(function(){
scope.spacer = (window.innerWidth < 1025) ? '' : 'large-3';
scope.button = (window.innerWidth < 1025) ? '' : 'large-6';
});
});
}
};
});
And if it's pertinent here's the HTML

Can someone point me in the right direction? I have done my best to follow the documentation, and looking through SO most of the related issues are much more in depth, and more difficult for me to understand. This is my first time creating a service.
also one of the popular reasons maybe you miss to include the service file in your page
<script src="myservice.js"></script>
Your angular module needs to be initialized properly. The global object app needs to be defined and initialized correctly to inject the service.
Please see below sample code for reference:
app.js
var app = angular.module('SampleApp',['ngRoute']); //You can inject the dependencies within the square bracket
app.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
$routeProvider
.when('/', {
templateUrl:"partials/login.html",
controller:"login"
});
$locationProvider
.html5Mode(true);
}]);
app.factory('getSettings', ['$http', '$q', function($http, $q) {
return {
//Code edited to create a function as when you require service it returns object by default so you can't return function directly. That's what understand...
getSetting: function (type) {
var q = $q.defer();
$http.get('models/settings.json').success(function (data) {
q.resolve(function() {
var settings = jQuery.parseJSON(data);
return settings[type];
});
});
return q.promise;
}
}
}]);
app.controller("globalControl", ['$scope','getSettings', function ($scope,getSettings) {
//Modified the function call for updated service
var loadSettings = getSettings.getSetting('global');
loadSettings.then(function(val) {
$scope.settings = val;
});
}]);
Sample HTML code should be like this:
<!DOCTYPE html>
<html>
<head lang="en">
<title>Sample Application</title>
</head>
<body ng-app="SampleApp" ng-controller="globalControl">
<div>
Your UI elements go here
</div>
<script src="app.js"></script>
</body>
</html>
Please note that the controller is not binding to an HTML tag but to the body tag. Also, please try to include your custom scripts at end of the HTML page as this is a standard practice to follow for performance reasons.
I hope this will solve your basic injection issue.
app.factory('getSettings', ['$http','$q' /*here!!!*/,function($http, $q) {
you need to declare ALL your dependencies OR none and you forgot to declare $q .
edit:
controller.js : login, dont return ""
This error is also appears when one accidntally injects $scope into theirs factory:
angular.module('m', [])
.factory('util', function ($scope) { // <-- this '$scope' gives 'Unknown provider' when one attempts to inject 'util'
// ...
});
Spent a few hours trying to solve the same. This is how I did it:
app.js:
var myApp = angular.module( 'myApp', ['ngRoute', 'ngResource', 'CustomServices'] );
CustomServices is a new module I created and placed in a separate file called services.js
_Layout.cshtml:
<script src="~/Scripts/app.js"></script>
<script src="~/Scripts/services/services.js"></script>
services.js:
var app = angular.module('CustomServices', []);
app.factory( 'GetPeopleList', ['$http', '$log','$q', function ( $http, $log, $q )
{
//Your code here
}
app.js
myApp.controller( 'mainController', ['$scope', '$http', '$route', '$routeParams', '$location', 'GetPeopleList', function ( $scope, $http, $route, $routeParams, $location, GetPeopleList )
You have to bind your service to your new module in the services.js file AND of course you have to use that new module in the creation of your main app module (app.js) AND also declare the use of the service in the controller you want to use it in.
I was getting this problem and it turned out I had included my controller both in ui.router and in the html template as in
.config(['$stateProvider',
function($stateProvider) {
$stateProvider.state('dashboard', {
url: '/dashboard',
templateUrl: 'dashboard/views/index.html',
controller: 'DashboardController'
});
}
]);
and
<section data-ng-controller="DashboardController">
Please "include" both Controller and the module(s) where the controller and the functions called in the Controller are.
module(theModule);

I just tried this, a VERY basic example:
HTML file
<!DOCTYPE html>
<html lang="en" ng-app="app">
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.6/angular.min.js" type="text/javascript"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.6/angular-route.min.js" type="text/javascript"></script>
<script src="./app.js" type="text/javascript"></script>
</head>
<body>
<div ng-controller="MailDetailCtrl">
</div>
</body>
</html>
The javascript file:
var myApp= angular.module('app', ['ngRoute']);
myApp.factory('mailService' , function () {
return {
getData : function(){
var employees = [{name: 'John Doe', id: '1'},
{name: 'Mary Homes', id: '2'},
{name: 'Chris Karl', id: '3'}
];
return employees;
}
};
});
myApp.controller('MailDetailCtrl',['$scope', 'mailService', function($scope, mailService) {
alert(mailService.getData()[0].name);
}]);
And it works. Try it.
Be sure that you load controller outsideapp.config. The following code may cause this error:
app.config(["$stateProvider", "$urlRouterProvider", function ($stateProvider, $urlRouterProvider) {
var AuthCtrl = require('components/auth/AuthCtrl'); //NOTICE HERE
$stateProvider.state('login',{
url: "/users/login",
templateUrl: require("components/auth/login.tpl.html"),
controller: AuthCtrl // ERROR
})
}))
To fix this error, we must move AuthCtrl to outsideapp.config:
var AuthCtrl = require('components/auth/AuthCtrl'); //NOTICE HERE
app.config(["$stateProvider", "$urlRouterProvider", function ($stateProvider, $urlRouterProvider) {
$stateProvider.state('login',{
url: "/users/login",
templateUrl: require("components/auth/login.tpl.html"),
controller: AuthCtrl // WORK
});
}))
In my case, I added a new service (file) to my app. That new service is injected in an existing controller. I did not miss new service dependency injection into that existing controller and did not declare my app module no more than one place. The same exception is thrown when I re-run my web app and my browser cache is not reset with a new service file codes. I simply refreshed my browser to get that new service file for browser cache, and the problem was gone.
Since this is the first Stackoverflow question that appears on Google when searching for Error: $injector:unpr Unknown Provider I'll add this here.
Make sure that in your index.html any modules/dependencies are not being loaded after they are needed.
For example in my code customFactory.factory.js begins like this:
angular
.module("app.module1")
.factory("customFactory", customFactory);
However the index.html looked like this:
<script src="/src/client/app/customFactory.factory.js"></script>
<script src="/src/client/app/module1.module.js"></script>
Where it should've really looked like this:
<script src="/src/client/app/module1.module.js"></script>
<script src="/src/client/app/customFactory.factory.js"></script>
Since customFactory.factory.js is declared as part of module1, it needs to be loaded before customFactory
I got this error writing a Jasmine unit test. I had the line:
angular.injector(['myModule'])
It needed to be:
angular.injector(['ng', 'myModule'])
When you are using ui-router, you should not use ng-controller anywhere. Your controllers are automatically instantiated for a ui-view when their appropriate states are activated.
I'm trying to create a small note-taking application using AngularJS, but I stumbled at the very beginning. Here's my .js file:
var app = angular.module("app", ['ngResource']);
app.factory("note", ['$resource', function($resource){
return $resource("/api/notes/:id", {id:'#id'}, {
query: {method: "GET", isArray: true}});
}
]
);
app.controller("NotesController", function($scope, $note){
console.log("I am being constructed");
$scope.notes = $note.query();
});
And here's the html file:
<html>
<head>
<title>Jotted</title>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.min.js"></script>
<script src="js/controllers/controllers.js"></script>
<script src="http://code.angularjs.org/1.0.6/angular-resource.js"></script>
<link href='style/main.css' rel='stylesheet'>
</head>
<body ng-app="app" >
<div ng-controller="NotesController">
<div ng-repeat="note in notes">
{{note.title}}
</div>
</div>
</body>
</html>
I've tried adding
NotesController.$inject("$scope", "Note");
but it only gave ma an error saying that NotesController does not have a method named "$inject".
Nothing is displayed and the browser returns an error: "Error: Unknown provider: $noteProvider <- $note". Certainly I am missing something obvious, but I can't put my finger on it. Where does the problem lie?
Remove the $ Sign before your $note. The dollar Sign is only a convention of the Framework to identify internal Providers,... .
For example try:
var app = angular.module("app", ['ngResource']);
app.factory("note", ['$resource', function($resource){
return $resource("/api/notes/:id", {id:'#id'}, {
query: {method: "GET", isArray: true}});
}
]
);
app.controller("NotesController", function($scope, note){
console.log("I am being constructed");
$scope.notes = note.query();
});
