sw-precache with angularJs application not caching

Question

I am newbie to service worker concept so forgive me if I am overlooking something from documentation. I have an angular application already running in production and I am trying to introduce service worker using sw-precache. To start with I am trying to precache all images/fonts and couple of js files and see if it works, so my precache config is like this -

{
  "cacheId": "static-cache",
  "importScripts": [
    "sw-toolbox.js"
  ],
  "stripPrefix": "dist/",
  "verbose": true,
  "staticFileGlobs": [
    "dist/img/**.*",
    "dist/javascripts/require.js",
    "dist/stylesheets/**.*",
    "dist/webfonts/**.{ttf, eot, woff}",
    "sw-toolbox.js",
    "service-worker.js"
  ]
}

Now I can see service worker registered and installed properly and cache storage shows all the urls with _sw-precache hashes.

But when I load the application and see in network tab all static content are still served from memory/disk, not from service worker and I am unable to debug why is it so. Am I missing something here -

UPDATE: More information: I had wrong configurations since I have dynamic url and server side rendered html. Server side it's test.jsp which is giving me initial shell. For now I have removed all other static files from cache and kept only show.css

So update config now is -

{
  "importScripts": [
    "sw-toolbox.js"
  ],
  "stripPrefix": "dist/",
  "verbose": true,
  "staticFileGlobs": [
    "dist/stylesheets/show.css"
  ],

  "dynamicUrlToDependencies": {
    "/developers": ["dist/stylesheets/show.css"]
  },

  "navigateFallback": "/developers"
}

Web root folder is named differently and it is - - dashboard -- img -- javascripts -- service-worker.js -- sw-toolbox.js - test.jsp And I see /developers url as an entry in storage cache, but still it's not served from service worker for next refresh. I have tried all my energy to fix this, but I desperately need some clue here, what's missing in here. TIA. Let me know if need more info.

It seems that whitespaces in your file extension list are not allowed. Your definition for webfonts should be:

"dist/webfonts/**.{ttf,eot,woff}",

I cloned the sw-precache repo and added a unit test where I compared two generated files with two diffrent staticFileGlobs, one with whitespace and one without.

it('should handle multiple file extensions', function(done) {
var config = {
  logger: NOOP,
  staticFileGlobs: [
    'test/data/one/*.{txt,rmd}'
  ],
  stripPrefix: 'test'
};

var configPrime = {
  logger: NOOP,
  staticFileGlobs: [
    'test/data/one/*.{txt, rmd}'
  ],
};

generate(config, function(error, responseString) {
  assert.ifError(error);
  generate(configPrime, function(error, responseStringPrime) {
    assert.ifError(error);
    console.log('responseStringPrime',responseString);
    assert.strictEqual(responseString, responseStringPrime);
    done();
  });
});

});

and it failed. The second config didn't include the .rmd file:

  -var precacheConfig = [["/data/one/a.rmd","0cc175b9c0f1b6a831c399e269772661"],["/data/one/a.txt","933222b19ff3e7ea5f65517ea1f7d57e"],["/data/one/c.txt","fa1f726044eed39debea9998ab700388"]];

versus

  +var precacheConfig = [["test/data/one/a.txt","933222b19ff3e7ea5f65517ea1f7d57e"],["test/data/one/c.txt","fa1f726044eed39debea9998ab700388"]];

thanks @stef-chäser, this is one of the mistakes. I have updated my question by removing all static but keeping only show.css for now, I just want to make my app-shell cache working first and further improve the app. I am unable to cache my appshell though I see url entry in storage cache.
