Angular UI Router not matching URL path - angularjs

When I go to localhost:3000/login, I'm redirected to localhost:3000/login#/login. How is that happening? I'm using the 1.3 release of AngularJS if that matters.
(function() {
this.app.config([
'$stateProvider', '$urlRouterProvider', function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/login');
$stateProvider.state('register', {
url: '/register',
templateUrl: '/components/user/register.html',
controller: 'UserCtrl'
}).state('login', {
url: '/login',
templateUrl: '/assets/components/auth/login.html',
controller: 'AuthCtrl'
});
}
]);
}).call(this);

The reason you are seeing localhost:3000/login#/login is because your $stateProvider configuration uses the .otherwise route which goes to #/login. The first /login is part of your URL path to the endpoint that retrieves the HTML for your Single Page Application (SPA) - it is part of your base URL.
For developers first starting out with SPAs, it might appear counter-intuitive that "navigation" in the app doesn't actually change the URL path - and thus endpoints of the server. Because of that there are no HTTP requests or HTTP-302 redirects. The app (or Angular, in this case) only changes the fragment (#) portion of the URL - that is how $stateProvider or $routeProvider "navigation" works.
So, the routes you configure in SPA determine "logically" which view to show. While the content of the view could load from an external URL, it is not related to the "route" definition itself.
Determine where your SPA will live. Determine what belongs to your SPA and what doesn't - and would be serviced by a different endpoint. Within SPA, "navigate" via #/path/to/view-style routes. Change url via $location.path to navigate outside of your SPA to a different endpoint.
== Same endpoint / different "routes" - all part of the same App:
baseurl.com/basePath#/about
baseurl.com/basePath#/login
baseurl.com/basePath#/product/153
== Different endpoints - different apps. Each one is an HTTP request to the server:
baseurl.com/basePath/about
baseurl.com/basePath/login
baseurl.com/basePath/product/153/
EDIT:
It is possible to use /page-view/other/params without #, turns out. Take a look at the following SO question.
In short, it's called HTML5 mode, and it can be configured with $locationProvider:
$locationProvider.html5Mode(true);
This however requires a bit more configuration and also more configuration on the server: https://github.com/angular-ui/ui-router/wiki/Frequently-Asked-Questions#how-to-configure-your-server-to-work-with-html5mode

Angular state provider not displaying full URL

I just inherited an application where there are several ui-sref="portal.main.content" in the code.
What I'm confused about is, to navigate to this state, we need to enter /#/portal/main/content.
However it is rendered on the page without the #. So it will work when clicking on the page, however it won't work if I try to open into a new tab as that page doesn't exist. What am I missing here?
The problem comes from the fact that your application is served from a server environment that deals with urls as if they were real paths for real resources on the server file system. Therefore, when your are in a single page, it's not reloaded when you navigate to another state url, because ui-router handle this internally, consequently doesn't produce 404 or 403 errors, but when you load a page first time, it's required from the server and gives you 404 and 403 errors because the resource you're looking for doesn't exists or is forbidden.
What you have to do is to configure your server side environment to target the index.html page when your are not refering to a file (like css and js files), so all url will end up in the index.html page with an url to be handled by the ui-router. Each server side technology (Apache, IIS, node.js, etc) will have a different way to handle this, but mostly have a URL Rewrite module and similar ways to handle this.
Also, if it's not a problem by using the hash like url, you can disable html5Mode to prevent ui-router to do such thing. You can achieve this by injecting $locationProvider on your .config and disabling it like so: $locationProvider.html5Mode(false);
For example:
angular.module('myApp', ['ui.router'])
.config(function ($stateProvider, $locationProvider) {
$stateProvider
.state('home', {
url: '',
templateUrl: 'views/home.html',
controller: 'HomeCtrl'
})
.state('about', {
url: '/about',
templateUrl: 'views/about.html',
controller: 'aboutCtrl'
});
$locationProvider.html5Mode(false);
});

AngularJS Routing not working when url typed

So, I'm pretty new to AngularJS and I'm trying to use AngularJs ngRoute in my application.
It all works smoothly when I start at the application homepage:
http://localhost:8080/appName/
And when I click on links from this point it works smoothly.
However, when I type a URL that I know exists/works, it gives me a 404 error. If I go to that link by using the application instead of the url it loads fine, even though it has the same url.
Eg. http://localhost:8080/appName/search
will give a 404, even though that is the same url that is the default redirect.
Indeed, the only url that will load by typing in the location is the base URL I mentioned above.
My app.js looks like this:
app.config( ['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider){
$routeProvider
.when("/search", {
templateUrl: "search.html",
controller: "SearchController"
})
.when("/results", {
templateUrl: "results.html",
controller: "ResultsController"
})
.when("/browse", {
templateUrl: "browse.html",
controller: "BrowseController"
})
.otherwise({redirectTo:"/search"});
//This gets rid of the # on the urls to the templates
$locationProvider.html5Mode(true);
}]);
I am hosting this on a glassfish4 server.
Is there something obvious I am missing/misunderstanding about how ngRoute works? Is there some setting that I am missing?
All help appreciated...
EDIT 1: As #Matthew Green below says, I need to configure the webserver to return the index.html for all pages below
http://localhost:8080/appName
I know I am being completely dense here, but where abouts is this configured? I am hosting the code in a MAVEN Jersey-Quickstart-Webapp.
When you use ngRoute, you are using javascript to handle routing to create a SPA. That means you need to hit a real page that loads your routing for your application to know what page to route to.
For example, your http://localhost:8080/appName/ should be routing to your index.html which would contain the javascript for your routing. With that page loaded it knows how to handle the links you have in your application. However, if you were to go directly to http://localhost:8080/appName/pageName you also need that to load index.html, as it is the one that loads your routing. Once your routing is loaded it should direct you to the correct page in your application. Without redirecting in place, http://localhost:8080/appName/pageName is not a real page and therefore correctly returns a 404.
Knowing this, the thing you have to figure out is what kind of server setup you have to configure the appropriate redirects for everything under http://localhost:8080/appName/ to go to your index.html page.

html5Mode with base tag does not work on refresh

AngularJS - html5Mode - Cannot GET /login
So I have seen this post and my problem is very similar. I have used base tag to get my relative urls to work. And I have $locationProvider.html5Mode(true); in my application. Everything seems to work fine to keep /#/ urls out of the application, but when the user refreshes the browser it says page not found. The url it is going to is where my router should be pointing to:
$routeProvider
.when('/', {
templateUrl: 'views/coverPage.html',
controller: 'MainCtrl'
})
.when('/coverPage', {
templateUrl: 'views/coverPage.html',
controller: 'MainCtrl'
})
This is just an example of my router page. Again, this works when I link through a button, but when I load the url: http://www.someurl.com/somepath/coverPage it says page not found.
If it works fine, when navigating from a link but get a page not found when you refresh it appears to be a server side issue.
Be sure to acutally load the right angular app from the server at the specified url. You need a kind of wildcard url matching for the server side route. But without knowing more details of your application I can only guess.

AngularJS: how to enable $locationProvider.html5Mode with deeplinking

When enabling the html5Mode in AngularJS via $locationProvider.html5Mode(true), navigation seems to be skewed when you land on a page deeper in the site.
for example:
http://www.site.com
when i navigate to the root, i can click all links in the site, Angular's $routeProvider will take over navigating through the site and loading the correct views.
http://www.site.com/news/archive
but when i navigate to this url (or hit refresh when I'm on a deeplink like the above one...) this navigation is not working as I expect it to.
first of all, our as the Documentation for $locationProvider.html5Mode specifies, we catch all urls on the server, similar to the otherwise route in angular, and return the same html as the root domain. But if I then check the $location object from within the run function of angular, it tells me that http://www.site.com is my host and that /archive is my path. the $routeProvider arrives in the .otherwise() clause, since i only have /news/archive as a valid route. and the app does weird stuff.
Maybe the rewriting on the server needs to be done differently, or I need to specify stuff in angular, but currently i'm clueless as to why angular see's the path without the /news segment included.
example main.js:
// Create an application module
var App = angular.module('App', []);
App.config(['$routeProvider', '$locationProvider', function AppConfig($routeProvider, $locationProvider) {
$routeProvider
.when(
'/', {
redirectTo: '/home'
})
.when('/home', {
templateUrl: 'templates/home.html'
})
.when('/login', {
templateUrl: 'templates/login.html'
})
.when('/news', {
templateUrl: 'templates/news.html'
})
.when('/news/archive', {
templateUrl: 'templates/newsarchive.html'
})
// removed other routes ... *snip
.otherwise({
redirectTo: '/home'
}
);
// enable html5Mode for pushstate ('#'-less URLs)
$locationProvider.html5Mode(true);
$locationProvider.hashPrefix('!');
}]);
// Initialize the application
App.run(['$location', function AppRun($location) {
debugger; // -->> here i debug the $location object to see what angular see's as URL
}]);
Edit
as per request, more details on the server side:
the server side is organised by the routing of zend framework, and it handles it's own routes (for serving data to the frontend on specific /api urls, and at the end, there is a catch-all route if no specific other route is bound, it serves the same html as the root-route.
so it basically serves the homepage html on that deeplinked route.
Update 2
after looking into the problem we noticed this routing works fine as it is, on Angular 1.0.7 stable, but shows the above described behaviour in the Angular 1.1.5 unstable.
I've checked the change-logs but haven't found anything useful so far, I guess we can either submit it as a bug, or unwanted behaviour linked to a certain change they did, or just wait and see if it get's fixed in the later to be released stable version.
Found out that there's no bug there.
Just add:
<base href="/" />
to your <head />.
This was the best solution I found after more time than I care to admit. Basically, add target="_self" to each link that you need to insure a page reload.
http://blog.panjiesw.com/posts/2013/09/angularjs-normal-links-with-html5mode/
This problem was due to the use of AngularJS 1.1.5 (which was unstable, and obviously had some bug or different implementation of the routing than it was in 1.0.7)
turning it back to 1.0.7 solved the problem instantly.
have tried the 1.2.0rc1 version, but have not finished testing as I had to rewrite some of the router functionality since they took it out of the core.
anyway, this problem is fixed when using AngularJS vs 1.0.7.
Configure AngularJS
$location / switching between html5 and hashbang mode / link rewriting
Configure your server:
https://github.com/angular-ui/ui-router/wiki/Frequently-Asked-Questions#wiki-how-to-configure-your-server-to-work-with-html5mode
My problem solved with these :
1- Add this to your head :
<base href="/" />
2- Use this in app.config
$locationProvider.html5Mode(true);

Angularjs ngRoute # in URL

This is my angularjs routing
app.config(function($routeProvider, $locationProvider) {
$routeProvider.
when('/home', {
templateUrl: 'partials/home.html'
}).
otherwise({
redirectTo: '/'
});
if (window.history && window.history.pushState) {
$locationProvider.html5Mode({
enabled: true,
requireBase: false
});
}
});
This link works as expected
Home
However, when I type http://localhost:3000/home directly in the address bar, I get a blank page. Any idea why this is happening?
Typing http://localhost:3000/#/home redirects to http://localhost:3000/home and works as expected.
AngularJS in html5Mode uses html5 history routing to get rid of the # in the url. This works as long as you navigate in the webpage.
The browser requested your index.html once (which set up your app and especially ngRoute), and clicking Home etc. does not cause requests to the server. Instead, ngRoute looks up the route, manipulates the html5 history and shows you what you clicked.
However, you have to tell the browser that performs the localhost:3000/home request someone typed into the url bar that he in fact wants index.html (not home/index.html, which does not exist). This means you have to configure your server to support html5 history routing. The $location documentation has a long post about this.
Here's what you'd add if you use express:
// this must be the last middleware added to your express app
app.use(function(req, res) {
res.sendFile('index.html'); // specify the path to your index.html here
});
If you type /home directly to the address bar, you're asking the server for a document in the /home path, when you actually want the AngularJS application in a document in the root path to load the /home route. You need to configure your server to redirect any request other than the root path to the root path, and pass the specified path after a #, for example, redirect /home to #/home.
Angular uses ngRoutes to navigate without leaving the page. If your route contains the # sign followed by the route then you are still on the same page. Angular does this so that it can have persistent variables between views. If you redirect to /home instead of #/home you are loading a static path to the /home folder on your server and Angular will reload when the new page loads, all variables will be cleared.
