AngularJS ui.router root state should be called always during app init - angularjs

I am working on web application using AngularJS and have used ui.router for routing.
I have configured the app
.state('init', {
url: '/',
controller: 'LocalizationCtrl',
templateUrl: 'partials/common/init.html'
})
.state('login', {
url: '/login',
templateUrl: 'partials/auth/login.html',
controller: 'LoginCtrl',
resolve: {
skipIfLoggedIn: skipIfLoggedIn
}
});
In init I load the localization json from server
If I hit the following URL it all works fine
http://localhost/app/index.html
However if I hit the following URL or any other state directly the localization files do not load
http://localhost/app/index.html#/login
How can I make sure that when app is loaded first using any URL the localization code should execute and not bypassed.

/ Bu default go to state -
angular.module('yourModuleName').run(["$location", function ($location) {
$location.url('/');
}]);
So, when you refresh or take your web application, your site will go to url /, so it should invoke your state, init to work.
Or you can use $state to go to a state upon starts
/ Bu default go to state -
angular.module('yourModuleName').run(["$state", function ($state) {
$state.go('init');
}]);

Its very simple there is a property "Resolve" you can use that.
In your parent state you can write this -
.state('parentState', {
resolve : {
localize : function() {
//Localization code here
}
}
};
Resolve will ensure that your localization work will be done before controller is loaded.

Misbehaviour on routes with Laravel 5.3 and AngularJS 1.5

I try to create an app with Laravel 5.3 and AngularJS. I want to use the routes and templates from Angular instead of Laravel.
Here is the web.php file from Laravel:
Route::get('/', function () {
return view('index');
});
And here is a part of the ui-router in AngularJS:
routeConfig.$inject = ['$stateProvider'];
function routeConfig ($stateProvider) {
// Routes
$stateProvider
.state('home', {
url: '/',
templateUrl: 'app/views/home.html'
})
.state('register', {
url: '/register?oauth_token&oauth_verifier',
templateUrl: 'app/views/register.html',
controller: 'RegisterController',
controllerAs: 'registerCtrl'
})
};
I have also enabled the html5mode and the base url on head. The problem now:
When I am at home and click the link to go on register page, it works. But If I try to load directly the register page, it loads it through laravel routes and since I haven't mentioned anything about it there, I have a NotFoundHttpException.
That's because when you refresh all routes are handled by laravel first.
I had the same problem and there are 2 approaches:
either put the angular app on a different domain ... but you will run
into CORS issues
or tell laravel to route any route to angular app, and that's easier
Route::any('{path?}', function()
{
return view("index");
})->where("path", ".+");

Subfolder routing doesn't work while angularjs works with spring

I am using spring and angular js in my project. In spring I set the view resolver as follows,
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/views/");
return viewResolver;
}
In angularjs ,I'm trying to route views/subview/test.html. Code as follows,
$stateProvider
.state("test", {url: "/test", templateUrl: "subview/test.html"});
});
Here the subview is the child folder of view folder.Since I set the view resolver to view folder only it not supports the view/subview/test.html.
Is it possible to setPrefix to all subfolders? If not, suggest other ways to handle this problem.
no you will need to set the full path each time - the path is relative to the top level html page the app is running in - you could of course use variables to manage this e.g.
var baseTemplatePath = "/WEB-INF/views/";
$stateProvider
.state("test", {url: "/test", templateUrl: baseTemplatePath + "subview/test.html"});
});
you could also put the variable in a higher level service for access everywhere.
angular.app("yourApp")
.service("pathService", function() {
return {
baseTemplatePath: "/WEB-INF/views/"
};
});
and then use (making sure you have injected the pathService):
$stateProvider
.state("test", {url: "/test", templateUrl: pathService.baseTemplatePath + "subview/test.html"});
});

How to catch the invalid URL?

I am building a simple HTML site using Angular JS ui-router.
I have built a custom 404 page ('www.mysite/#/error/404'), to which the user is redirected if the user types a url like 'www.mysite/#/invalidUrl'. This functionality was achieved by the following code snippet:
$urlRouterProvider
.when('', '/')
.when('/home', '/')
.otherwise('/error/404');
And the following state snippet:
$stateProvider.state('404', {
parent: 'app',
url: '^/error/404',
views: {
'errorContent#main': {
controller: 'error404Controller',
templateUrl: 'js/general/templates/error404.html'
}
}
});
I am trying to capture the invalid URL requested by the user to be displayed to the user like below.
The URL you requested cannot be found
Request: www.mysite.com/#/invalidUrl
I have tried listening to '$stateNotFound' event, which only seems to be firing when a specific invalid state is requested. I've also tried to listening to events '$stateChangeStart', '$locationChangeStart', and '$locationChangeSuccess' but couldn't find a way to achieve this functionality.
Is this possible? Please, share your thoughts - thank you
Awesome! Thank you Radim Köhler. I don't know how I didn't land on that thread when I searched but that helped me get the answer.
I changed the answer in that thread to fit my scenario which I am going to leave below for reference to any other users.
$stateProvider.state('404', {
parent: 'app',
url: '^/error/404',
views: {
'errorContent#main': {
controller: 'error404Controller',
templateUrl: 'js/general/templates/error404.html'
}
}
});
$urlRouterProvider
.when('', '/')
.when('/home', '/')
.otherwise(function ($injector, $location) {
var state = $injector.get('$state');
state.go('404', { url: $location.path() }, { location: true });
});
So the magic change was the function defined for 'otherwise' option. I didn't change the URL of the 'error' state. Instead, I used the 'state.go' to activate state '404' and passed the location path as the state parameter.
Setting location=true will take you to the URL of the state, and location=false will not. Whichever way you prefer the invalid URL can be accessed easily now.

AngularJS. Retain state after page reload

I am using UI Router with html5Mode enabled, states are loaded from JSON.
Expected behavior after F5 or when pasting URL is, respectively, having current state reloaded or navigating to the said state, instead the initial application state is loaded.
For e.g. root/parent/child gets redirected to root/.
By the way, navigating with ui-sref works fine.
So, how can the state be retained after page reload?
In order to retain the state of page after reload app, a url represent the state should be gave. when you include ui-route module, url will be parsed and sent to corresponding state. You don't need to parse the url handly in most cases, ui-route born to do this.
Please can you post your code here? Specifically the $stateProvider.
This is an example of a correct $stateProvider and it works fine:
$stateProvider.state('main.admin', {
url: '/admin',
resolve: {},
views: {
'main-content#main': {
controller: 'AdminController as admin',
templateUrl: 'main/admin/admin.tpl.html'
}
}
});
Seems a bit hacky, but works for now.
app.run(['$location', '$state', function ($location, $state) {
function stateFromUrl () {
var path = $location.path(),
hash = $location.hash();
// do JSON states map parsing and find a corresponding to the URL state
return state;
}
if (stateFromUrl) {
$state.go(stateFromUrl);
} else {
$state.go('home'); // initial state
}
}]);

AngularJS + Adobe CQ5 - Browser URL does not append hash path but changes the view

I am using combination of AngularJS and Adobe CQ5.
I have implemented routing to load different views. The views are loading perfectly but the URL is not appending the #/path and it shows the base path only, e.g.
localhost:7001/cf#/content/requestpage.html#/
rather than
localhost:7001/cf#/content/requestpage.html#/checkstatus.
Due to this, when I refresh the page it loads the route path (/) template instead of loading the same view again.
I am struggling to resolve this issue. Here's my controller code:
var demoapp=angular.module('demoApp',['ngRoute','ngSanitize']);
demoapp.config(function($routeProvider,$locationProvider) {
// use the HTML5 History API
//$locationProvider.html5mode(false);
$routeProvider
.when('/', {
templateUrl: '/content/index.html?wcmmode=disabled',
controller: 'myfirstcontroller'
})
.when('/checkstatus', {
templateUrl: '/content/housetemplate.html?wcmmode=disabled',
controller: 'houseController'
})
.otherwise({
redirectTo: '/'
});
});
demoapp.controller('houseController', function($scope, $routeParams,$http)
{
//code
});
demoapp.controller('myfirstcontroller', function($scope,$http,$rootScope,$location,$compile)
{
//On Form Submit
$scope.continueForm = function(isValid){
if (isValid)
{
$location.path('/checkstatus');
}
});
});
This is not an issue with CQ5. When you open a page from Siteadmin, by default your page is loaded within contentfinder (/cf#).
Now, contentfinder already has your page URL as the hashvalue. Hence you find that the URL doesn't get updated even though your angular views work correctly.
Try accessing the same page without contentfinder. i.e.,
http://localhost:7001/content/requestpage.html
instead of
http://localhost:7001/cf#/content/requestpage.html
You should find things working as expected.
