Ember CLI / browser refresh / production / 404 - ember.js

I developed my webapp using Ember CLI 0.1.15, with emberjs. 1.8.1
I built the app with this command: ember build --environment production , and then I made a WAR out of the files produced under the dist folder of my project, and then I drop the WAR on my tomcat's webapps folder.
So, when I open the app: http://mytomcat/myapp/ ... it went fine, I saw my login screen, I logged in, and navigate around in my app, everythings fine. I could also do the back/forward button, and ember handles the transition well.
But when I click the refresh button on my browser -- the address bar of the browser was showing http://mytomcat/myapp/inventory/ at that moment -- I got 404 reply, from the tomcat.
Then I figured out why it happened: the refresh button sends a request to the tomcat for the path /myapp/myinventory/ ... of course the path /myinventory does not exist on the server. All those routes we see on the browser -- except for the base url, http://mytomcat/myapp/ -- are generated on the client-side.
So, my question is: what's the right way (in ember) to deal with this situation? I need the refresh button to just works. Any way for ember to intercept the refresh button clicked event?
I guess this issues is related to this: https://github.com/stefanpenner/ember-app-kit/issues/486 , but it does not have the answer I need.
Thanks in advance,
Raka

Inside config/environment.js file, there is a property called locationType. Set its value to hash
Manually moving files from your /dist folder is time consuming and annoying. Instead, you can specify an output-path property in your .ember-cli with the location inside webapps you are trying to move the files to. Another option is to specify this option to ember server or ember build

Generating Production Build index.html With Server Side App

I want to do something very simple that I am a little surprised people are not talking about more. I would like to generate on my server my own index.html from the files that are created from building ember for production. I use ember for part of my application and so when a certain URL is hit, I would then like my ember app to take over. I have tried generating my own index.html by changing the flag storeConfigInMeta in ember-cli-build.js.
storeConfigInMeta: false
This gets rid of the ember app having its configuration stored in a meta tag but the app still does not work and gives the error,
Uncaught ReferenceError: define is not defined
I have the latest version of ember and I am building ember with the command,
ember build --env production
My server generated index.html looks identical accept for the integrity attributes set on the include js and css scripts. Is their anything I am missing about approaching ember this way? Should I not be trying to do this?
when a certain URL is hit, I would then like my ember app to take
over.
You need to configure app server to return index.html file for the certain URL.
Generally, it's not required you to create your own index.html.
May be you can check ember-islands addon to include Ember components anywhere on a server-rendered page.
I made a mistake. I was grabbing the production assets with a regular expression with my server and generating my index.html file with these assets in the wrong order. To anyone looking to do this, it is very possible and is more preferable in my opinion to using the generated index.html unless you are using ember for your entire site's routing. However do use the setting in ember-cli-build.js,
storeConfigInMeta: false
This will make it so your ember app stores it's settings in javascript instead of in a tag. This is required for generating your own index.html file.

Ember routing non-root domain

I am using the ember quick-start tutorial app. Everything works great locally, but when deployed to a test environment the app is 404ing on loading all resources.
I am deployed to a subfolder out somewhere and apparently ember is trying to find it against the root domain, instead of subfolder
Example:
http://example.com/embertest/index.html
The assets folder is obviously under http://example.com/embertest/assets/, but on load it's trying to grab it from http://example.com/assets/ which doesn't exist
How can I have ember use relative paths in this case?
Update 1
After some googling I tried editing the environment.js ENV.baseURL attribute
In the if(environment === 'production') block I added ENV.baseURL = '/website/dist/';, obviously I am building with ember build --env production
I am getting same 404s when going directly to a route but now also getting an error on index.html, Uncaught UnrecognizedURLError: /index.html
I tried every combination of '/website/dist/', 'website/dist/', '/website/dist' as well
Update 2
I have now also tried manually editing the <base href="/website/dist/"> in my index.html after a prod build. Same errors as from update 1
You need to understand that you can't just put an ember application to a normal webserver folder. Ember uses the history API to change the URL when you do a route change but it can't control what your web server deploys when its directly fetched.
So you have your ember index.html on http://example.com/app/index.html your web server usually will only deploy this file when you open http://example.com/app/ or http://example.com/app/index.html. But for a route foo your url is http://example.com/app/foo and your web server is looking for a directly foo that does not exist. So you have to configure your web server so its always responding with your index.html if your not requesting another existing resource (like an image, js or css file)!
How to do this depends completely on your webserver.
You must also notice that you should enter your assets in a full root relative path and specify rootURL so your router knows which part of the URL is your path and where your routing begins.
You should not use baseURL because its an upcoming deprecation!
You really should read this really new blog post!
Use ENV.locationType = 'hash' to prevent the usage of the history API is still always an option, but definitly an ugly one.
Okay so I solved this by changing ENV.locationType = 'hash' in environment.js
Would still love an explanation of what's going on as this feels a little bit hacky...

Ember 2.0 not live reloading

I created a new app using the ember-cli. It creates the project just fine. I updated the 'bower.json' file to use 2.0.0 for both Ember and Ember Data and installed them. The core of my application setup works how it should.
When I do 'ember serve', my application opens at localhost:4200 but is constantly showing the reload gif on the tab and the status bar at the bottom of the screen continues to show 'waiting for localhost...'. The 'Welcome To Ember' text shows. Any changes I make are not live reloaded in my browser, however, a hard reload shows the changes even when just trying to edit the application.hbs file. Any ideas as to what's going on?
Are you on windows? It sounds like this bug that is currently being worked on.
https://github.com/ember-cli/ember-cli/issues/5123
For me ember serve --lrp 9000 worked and fixed live-reload.
(I tried the other suggestion to use ember serve host 0.0.0.0 and it stopped the "loading" spinner, but live-reload still did not work.)

Use of window.location.href in crosswalk

I use crosswalk 5.34.104.5 to build Android app.
After executing
location.href = '/another_page.html'
in index.html, which is a entry point defined by manifest.json,
empty alert pops up and blank page appears.
another_page.html is located in the same directory as index.html
(i.e. it is in apk file whose path is assets/www/another_page.html relative to apk's root)
and is not served over network.
How can I achieve intended location transition?
It is a typo in "asserts/www/another_page.html", it should be assets, right? I can do the same thing with changing location.href to load another page.
EDIT: If you are using make_apk.py to package your app, you can pass "--enable-remote-debugging" to turn on remote debugging for your app. Once the app is launched on your device, open 'chrome://inspect' in Chrome browser running on the host machine, and inspect the page to directly execute "window.location.href=xxx" in console, and try to fix your problem. See https://crosswalk-project.org/#wiki/Remote-Debugging-on-Android for details.

EAK and tastypie adapter integration

What is the best approach to use EAK and ember-data-tastypie-adapter?
I am currently trying the following:
Django running on localhost:7000
EAK running on localhost:8000
Added ember-data-tastypie-adapter to bower.json
Added both JS files to index.html
<script src="/vendor/ember-data-tastypie-adapter/packages/ember-data-tastypie-adapter/lib/tastypie_adapter.js"></script>
<script src="/vendor/ember-data-tastypie-adapter/packages/ember-data-tastypie-adapter/lib/tastypie_serializer.js"></script>
Created everything needed on Django side
I figured that I had to create serializers/application.js and put in it:
export default DS.DjangoTastypieSerializer.extend();
Also adapters/application.js needed adjustments:
export default DS.DjangoTastypieAdapter.extend({
serverDomain: 'http://localhost:7000',
});
Requests go to Django and responses are sent.
However in EAK this gives "Sorry, something went wrong" message without any further information (empty error message box). No errors in console either.
If I remove serializers/application.js I get similar message, in this case with information about the error:
Assertion Failed: Nested controllers need be referenced as [/django/tastypie],
instead of [_djangoTastypie].
Refer documentation: http://iamstef.net/ember-app-kit/guides/naming-conventions.html
Do I have to define defaultSerializer in adapters/application.js? If so, what is it, /django/tastypie or something else?
What am I missing to integrate ember-data-tastypie-adapter in EAK? Trouble is, I have not seen any example where EAK and tastypie would be working together.
Of course this two local server system is development environment. Production is planned like here, both API and JS is served by one Django instance.
UPDATE:
Creating deployment code by grunt dist and serving it using Django works.
I suspect that problem lies with different JSON origin.
Turns out, that EAK has API proxy option.
Updated package.json to my API settings:
"proxyURL": "http://localhost:7000",
"proxyPath": "/api/v1",
Removed custom settings from adapters/application.js.
Now running grunt server:proxy gets data from Django. And ember.js app works without errors, not being same origin was most likely the problem.
