AngularJS Architecture: Basic State with ui-router

We will look at ui-router and learn how we can use it to define unique states with Eggly. This will allow us to leverage the power of a state machine in our AngularJS application, which goes beyond code management and into managing the states that exist within the code.

note the route doesn't actually fire unless you navigate to index.html#/ instead of index.html (see comments)

Upon downloading the finished source code for this lesson, it doesn't seem to be working properly. I thought it was something in my code that might be the problem - maybe copied something from the video incorrectly. However, after downloading the source code and resolving all the External Library source issues, the page is not pulling in the template. There are also no errors in the JS Console so I'm at a loss.... Can you please double check the source code that is on github is in fact not working properly and let me know?

Andy -- the problem is that the route doesn't actually fire unless you navigate to index.html#/ instead of index.html. This gets fixed in a later lesson as I force the default route to always be '/'. Please let me know if you have any more questions. Happy to help!

I was very confused why my code wasn't working until I read this. Thanks!

I'm getting a CORS error when trying to load src/app/categories/categories.tmpl.html. As far as I can tell, I'm requiring and referencing things in the correct fashion. I'm running the app directly from localhost. The domain in my browser and in the error seem to be the same.

Is it because ui-router uses HTTP requests to fetch files? Do I need to actually deploy this application locally somehow?

Hi Taylor --

Are you serving the project from an HTTP server? I generally run it out of WebStorm which gives me one for free or you can use the npm module serve which is also very handy.

I would of liked to have seen you follow your module/sub module pattern and write the routes for the modules into the modules themselves vs applying them to your "app.js" file.

Keep watching! :D I definitely end up there when it is all said and done.

Hi Lukas, please make sure you warn it on the video. Took me more than 3 hours to get it done.

I almost gave up, but than, I realise that I should've read all comments and here it is.

It worked with /#/.

Thanks anyway.

small contibution here...

go into 'src' folder or wherever the index.html file is located.

$python -m SimpleHTTPServer

then in your browser: localhost:8000 and that solves the CORS and avoid setting the '#/' manually at the end of the url

please let me know if this works for you ;)

btw firing up a server "solves" the //xxx.js files calls in html... without a server you had to "fix" the paths forcing to --> html://cdnjs..../xxx.js otherwise the browser will try to locate those dependencies in --> "file://cdnjs.../xxx.js"

May I have Kudos? :P

Hey Lukas,

Can you explain why only 'index.html#/' works? Super confused here :S...

Lukas Ruebbelke

Hi Jonathan -- The reason only index.html#/ works right now is because we haven't set up a fall back when a route is not matched precisely.

We will fix that in the next lesson when we add in $urlRouterProvider.otherwise('/'); via the $urlRouterProvider service.

I want to know if the code in https://github.com/eggheadio/egghead-angularjs-eggly-architecture/tree/03-ui-router-basic-state is ok?? I think that it does not work correctly.

Just a quick note, there is a typo at 3:18 in lesson 3 it shows eggly.models.model right at the end.

Hi Lukus, Either my IDE or my inexperience won’t allow me to use index#/. So, I found two other ways to solve this problem. One using $urlRouterProvider which you apply in ensuing lessons and the other way I found is by including the run method to navigate to the initial state. As follows: .run(['$state', function ($state) {$state.transitionTo('eggly'); }]) I don’t know what pitfalls (if any) lay ahead by using the run method but for this lesson it works well. Thanks, Brian

Hi Brian, Did you try using index.html#/? I see that you used index#/ (which does not work for me either) but if you use index.html#/, the state should resolve. Hope that helps!

Hey Lukas,

Is there any particular reason that you source the ui router from your own files in vendor, rather than pull from a cdn like you do for the rest?

Thanks!

Hi, Jonathan -- I was probably working on a plane that day :D In all seriousness, I prefer to use NPM to satisfy my dev dependencies these days.

Dear Lukas,

perhaps this is a silly question but does ui-router form part of the official angularjs code or did you get it from somewhere else? I know I can just copy the file from the github repo but I'd like to get it from the original source so I know where to find it for future reference. Thanks!

Lukas Ruebbelke

Hi Borja - ui-router is a standalone project that you can find here https://github.com/angular-ui/ui-router

Hope that helps!

Hi Lukas! When I try to access " eggly/src/index.html#/ ", it gets changed to " eggly/src/index.html#!#%2F ". Therefor I can't see the ui-view. Any suggestions?

Sina, I had what looks like the same problem you had, and it was because I was using angular 1.6.1. As of 1.6, they've changed how routing works. I was able to keep the new version of angular but I had to change the url property in eggly-app.js to '' (empty string) in order to get it to work. Then I could navigate to index.html without any #'s or /'s and routing worked.
