Angular UI-Router is a client-side Single Page Application routing framework for AngularJS. Routing frameworks for SPAs update the browser's URL as the user navigates through the app. Conversely, this allows changes to the browser's URL to drive navigation through the app, thus allowing the user to create a bookmark to a location deep within the SPA. UI-Router applications are modeled as a hierarchical tree of states. UI-Router provides a state machine to manage the transitions between those application states in a transaction-like manner.

Answered 2021-Aug-23 at 12:02It turns out, the listener I used is suboptimal when UI-Router is in use. In fact, I cannot even prevent the state change in my listener.
Instead, when using UI-Router, $transitions.onStart()
should be used for listening to state changes.
QUESTION
I have the simplest ui.router example which doesn't seem to work.
See below:
...ANSWER

QUESTION
First, let me say you will not be able to reproduce my problem unless you also are working in a healthcare situation using the latest athenaPractice EMR.
I just don't have any direction on where to troubleshoot this problem and looking for suggestions for what information or settings I should be checking.
I have an AngularJS SPA set up that routes 100% fine in a regular Chrome browser window locally served (http-server installed via npm). I can load the main app page by URL (localhost:port/app
, which redirects to /app/#!
) and I can load the subpage by URL (localhost:port/app/#!/page
). I can do it with or without a trailing /
. I can navigate from one view to the other by links on the page. Works great.
But I have a problem when I put it in the server location (which, if it's relevant, has a path longer than /app/ from the //localserver/
root), and load the file through the EMR (which is running Chromium). (Files are loaded in the EMR by adding a specially formatted file that links all included items in a form, which in the case of HTML files, is just a URL to a resource: //localserver/directory/subdirectory/app/#!/page
). It loads fine the first time, but if I try to load separately a different page (//localserver/directory/subdirectory/app/#!/
, for example), it shows the currently open page. It's almost like both instances of the browser are the same browser window and it doesn't bother to load a new window for the URL with the same address up to the #!
. I can navigate from one page to another by links but not by loading from the root address, and if I navigate under one "form", and click back to the other one, it's also been navigated, hence why I think it's only one instance of the window.
I tried HTML5 routing with no success since this is running in a JBoss 7.x server and I have had a very hard time finding any documentation that even comes close to matching the files I see on the server for URL rewriting access. (I have found instructions that reference files that don't exist in our installation, so I don't know if this has been customized by the application provider, or what.)
I don't have access to developer tools, console, or even the address bar through the EMR.
Any suggestions on where to go with troubleshooting this?
Edit to add: Might be worth noting that I have tried ngRoute and ui-router both with the same results.
...ANSWER
Answered 2021-May-03 at 21:01I got this working correctly. I don't know what the root cause in the EMR is, but it was treating each loaded route of the SPA as part of the same instance using #!
routes. Getting HTML5 routing working solved the issue.
After fighting with Undertow for a day and having no feedback on why my rules weren't working, I ended up using Tuckey's URL Rewrite. It helpfully logs what input it was comparing against what which allowed me to see where my first attempts at rules went wrong, and edit them accordingly until they worked.
This required three file changes in the WEB-INF
directory inside the application's .war
directory. (There are various META-INF and WEB-INF directories all over in this setup but using this one worked in the specific deployment I'm working in now, namely our demo server.)
Create a
/lib
directory insideWEB-INF
and puturlrewritefilter-4.0.4.jar
in it (downloaded from the Maven repository)Put the example
urlrewrite.xml
intoWEB-INF
and adapt it with necessary rules. For the root page of our SPA and the first route, the custom rules I inserted look something like this:

QUESTION
I have an angularjs/ui-router application. All the html templates, which are lazyloaded by the framework, are cachebusted so that they are named myTemplate.someHash.html
, and the references to those templates are also updated compile-time.
One problem that sometimes occurs is when I deploy a new version while a user is using the application. The sequence of events is as following:
- The user has opened a page, which has a link on it to a state called Summary. The Summary state uses an HTML template called
summary.html
. But since we're cachebustering the HTML templates, this file is actually namedsummary.12345.html
in version of the application currently loaded in the user´s browser. - A new release is deployed, which contained some changes to
summary.html
, causing it to get a new hash, so it's now calledsummary.98765.html
. - The user clicks on the link, and angular tries to fetch
summary.12345.html
which nolonger exists, causing a 404.
Is there a good pattern for solving this?
My initial thought is to append some HTTP header in all requests, something like Expected-Version: 999
(where 999 is the build number generated in CI), and if that is not the version running on the server, then the server will respond with something like "410 Gone", in which case the application will ask the user to refresh the browser.
But it would require some work on the server side, and I'm not sure how to inject this logic into the template loading on the client side either.
Also, since new versions are typically deployed a few times per week (sometimes many per day), and most of those releases don't even contain any changes that would break the SPA in the above way, I don't want to force the users to reload the page all the time.
Could one approach be to only show the "please refresh" message when a request results in a 404 AND the response contains a header that indicates that you're running a stale version of the SPA?
Or maybe there is a simpler way?
...ANSWER
Answered 2020-Dec-13 at 20:29I solved it in the following way.
I decided I don't want to ask users to refresh their browser every time a new release has been deployed, because many of those releases only contain backend changes.
I only want to ask them to refresh when a release has been deployed (since the time they opened the app in their browser) which contains changes to either:
- the javascript application (which is served as two bundles), or
- any of the html templates that angular lazyloads.
So I had to introduce the notion of a UI version. I decided that the definition of this UI version should be the SHA256 hash of all the filenames (just the names, since those already contain hashes for cachebusting) of the html templates mentioned above, concatenated with the names of the two js bundles (which are also cachebusted).
Here's the solution. Part 1I added a step in my CI pipeline, after the js app has been compiled and cachebusted, but before the whole application is built into a Docker image. This new build step looks like this:
QUESTION
I'm making a program to scrap some websites, and I'm finding a problem when scraping one of them. On the others I've found my way using Selenium + BS4 to get the information I need and navigating the pages.
The page is this one: https://www.borm.es/#/home/sumario/21-11-2020
Now, the objective is to get all the paragraphs from the class: ng-binding, and the links of each "VER ANUNCIO" that each one has below them.
Usually I would use soup.find_all() to get all of them and navigate the tree or use Selenium to get all the elements using XPATH/CSS SELECTOR.
The problem I'm facing is that find_all(), or find() is returning nothing, (empty list or None), and Selenium returns None too.
I've tried checking if the elements are inside a frame, which I think they're not. I've tried WebDriver wait to see if the page should stop to load before doing something. Different classes/tags give same result.
Now, when I print the BeautifulSoup object, it returns this instead of the HTML code I see inspecting the page:
...ANSWER
Answered 2020-Nov-21 at 12:57What is going on is that the page content that you are viewing is actually being loaded by JavaScript code that is being executed after the initial page content (which you have printed out and are searching) has loaded and that is why you are not finding the elements you are expecting. There are two ways of dealing with this:
- Use
Selenium
to drive a web browser such as Chrome to load the page and wait for an element that you are looking for to be loaded using a Selenium call. Then you can get fromSelenium
the current page source and initializeBeautifulSoup
with that and proceed as usual. This is the "standard" approach. - Using a browser inspector you can look at the network XHR requests that are being made after the page has loaded. One or more of these will be the cause of fetching additional data for updating the DOM. You can then note what the GET or POST request(s) was, make the request yourself and process the data directly.
For example:

In my application I have a blog home/list/add pages that do their respected parts. BlogHome or home.html will just show my name and a message that is in the controller. The home page is not displaying information that I have in the controller, but it is loading my navigation menu for the other pages. The information in the angular home.html is not being displayed but the nav bar which is outside the home.html is loading up in the browser.

QUESTION
I am trying to integrate Azure SSO into a new AngularJS application and I am struggling to find complete AngularJS examples that aren't written in Visual Studio. Anything that I come across is either incomplete and doesn't show how to deal with authenticated users, redirects, etc., or is in Visual Studio (which I don't want).
I have followed the tutorial for ADAL located here but it doesn't give a complete demonstration (only code fragments) and doesn't really explain how to deal with authenticated users. Is there anywhere I can find a complete AngularJS tutorial of how to integrate all features of Azure SSO?
I can get my app to call the microsoft login page, select my user and then request a password, but once that occurs, I am struggling with the Redirect URI. I am using UI-Router which means all my views are in the form of https://myapp.com/#!/auth
which Azure claims is not a valid URL to redirect to.
If I change my Redirect URI to anything past the base root (e.g. https://myapp.com/auth/
) I get an error every time I try and login:
AADSTS50011: The reply URL specified in the request does not match the reply URLs configured for the application
If I leave it as root, my application falls back to https://myapp.com/#!/
and doesn't recognise the logged in user.
Does anyone have any suggestions or can assist me in getting this integrated? Thanks.
...ANSWER
Answered 2020-Oct-14 at 23:08I managed to resolve this by adding the following command to my .config()
method:
$locationProvider.html5Mode(false).hashPrefix('');
This removed the !
from all my views and by making sure my application URL and redirect URL was the same in Azure (as recommended by @Sruthi J), this allowed the redirect to occur correctly.

QUESTION
[EDIT] I've created a demo repository with this error: https://github.com/SamanthaAdrichem/hybrid-lazy-load-angularjs-injector-error
We've followed the instructions, and all runs fine on normal hybrid, but adding lazy loading fails with the strange error above, and always implemented ui router the way the docs say (as you can see in the code below).
When loading the app all is fine, but when then clicking onto a lazy-loaded route we get the error
Transition Rejection($id: 0 type: 6, message: The transition errored, detail: Error: Trying to get the AngularJS injector before it being set.)
I've tried the solutions listed here
https://github.com/ui-router/angular-hybrid/issues/93
https://github.com/ui-router/angular-hybrid/issues/150
https://github.com/ui-router/angular-hybrid/issues/395
https://github.com/ui-router/sample-app-angular-hybrid/issues/10
But none of these solve it. We don't use ng serve because that crashes with random memory issues (probably also due to hybrid), and we need to proxy to a login page, but the login page and our project would be running on the same port, which isn't possible. So that needs some refactoring in the backend.
It does sometimes load a new chunk file depending on what page i'm going to. But mostly i get this error.
Funny part is, in the page i'm testing we're not using any hybrid code. Basically we're are no longer upgrading any code, we're only downgrading some observers to open modals of the older pages.
These are the versions we're running
