newbie - errors

[acerov]

Hi,

I am totally new to serviceworker. Just installed broccoli-serviceworker following the instructions on ember-cli 1.13.9 but when rest api server is not accessible I am receiving following errors:

Got error for dynamic url, try to pull from cache: TypeError: Failed to fetch at TypeError (native)

The FetchEvent for "http://localhost:4000/v1/clients" resulted in a network error response: an object that was not a Response was passed to respondWith().

@acerov what browser were you using? did you put your rest server api in the dynamicCache section in your environment.js file?

@jkleinsc chrome 46.0.2490.86 m, but I tried with firefox also (service worker not supported), in environment.js I have:
ENV.serviceWorker = { enabled: true, serviceWorkerFile: "service-worker.js", excludePaths: ['tests/', 'online.html',], includePaths: ['/'], fallback: [ '/online.html offline.html' ], dynamicCache: [ '/v1' ] };
I am using ember 1.13.9 and ember-data 1.13.14

You could try adding the debug option in environment.js to add console logging to see where the caching is failing:

javascript
ENV.serviceWorker = {
enabled: true,
serviceWorkerFile: "service-worker.js",
excludePaths: ['tests/', 'online.html',],
includePaths: ['/'],
fallback: [ '/online.html offline.html' ],
dynamicCache: [ '/v1' ],
debug: true
};

As an aside, I am planning on using [Google's Service Worker Toolbox](https://github.com/GoogleChrome/sw-toolbox) in the next version of broccoli-serviceworker, which should hopefully better handle or avoid errors like this.

@jkleinsc thank you for your effort but with debug: true nothing changed, just the same error from first post, no new error details

[jkleinsc]

Are you seeing any output in the developer console? debug:true adds console statements to the service worker so you can see what it is attempting to do. If you are not seeing any additional output try doing a refresh/hard refresh in your browser.

I had to go to chrome://inspect/#service-workers and click inspect and there are the same errors:
Handling fetch event for http://localhost:4000/v1/clients
Pulling dynamic url: http://localhost:4000/v1/clients from network and adding to cache.
Found dynamic cache response: http://localhost:4000/v1/clients

@acerov I am refactoring the code to use https://github.com/GoogleChrome/sw-toolbox which should resolve this issue. I will let you know when that update is available.

[acerov]

@jkleinsc great, I will be happy to test it :)

[jkleinsc]

@acerov I just published a new version 0.0.5 which should resolve your issue. Let me know if you still run into problems. One thing of note, the configuration has changed slightly - includePaths is now called precacheURLs.

@jkleinsc what can I say, it just works :) thank you!
