The `FETCH_ERROR` document is used when we are unable to retrieve a
document (except for 404 errors), which includes when there is no
internet connection. Using the `<current-location>` element in the
document's template to show the path of the page we failed to retrieve
assumes that the element's bundle is available (e.g. cached by the SW)
or can be fetched from the server.
When none of these conditions is met, the `DocViewer` is unable to
prepare the document and fails, never showing the `FETCH_ERROR` page to
the user.
Furthermore, the path we are looking to retrieve via
`<current-location>` is essentially the document ID, which we already
have. Thus, loading and instantiating a whole component just for that is
overkill.
This commit addresses both issues by getting rid of the
`<current-location>` component and directly embedding the document ID
into the `FETCH_ERROR` content.

AIO is currently using a beta version of @angular/service-worker.
Since that was implemented, the SW has been rewritten and released
as part of Angular 5.0.0. This commit updates AIO to use the latest
implementation, with an appropriate configuration file that caches
the various AIO assets in useful ways.

The `Logger.error()` method now only accepts a single `Error` parameter
and passes this through to the error handler.
This allows the error handler to serialize the error more accurately.
The various places that use `Logger.error()` have been updated.

Previously, the path returned by `LocationService.path()` preserved leading
slashes, which resulted in requests with consequtive slashes in the URL. Such
requests would fail (with a 404) on staging.
This commit fixes it, by removing leading slashes from the path. It also
refactors `LocationService` a bit, converting path to an observable,
`currentPath` (similar to `currentUrl`), and applies certain clean-ups (e.g.
stripping slashes, query, hash) in one place, which simplifies consumption.
Closes#16230
Dgeni is now providing the `id` for all the documents to be viewed. So we
no longer need to add this to the DocumentContents object.
There are some notable changes in the refactoring:
`DocumentService`:
* The id of the document to render is now obtained from `LocationService.path()`.
* The `getFileNotFoundDoc` and `getErrorDoc` methods have been extracted from
the `fetchDocument` method.
`AppComponent`:
* the `pageId` is now computed in a separate `setPageId` method.
`AppComponen` spec file:
* The `TestHttp` has had the hard coded documents removed and replaced with
a function that will generate docs as needed.
Previously, the `AppComponent.pageId` was set via the current URL, rather than
the document being displayed. This is only really noticeable when the URL does not
match a valid doc and we are actually displaying a 404 page.
Now we compute the `pageId` from the URL of the document being viewed,
which is returned from the `DocumentService.currentDocument` observable instead.
Content pages like `tutorial/index.md` were being mapped to `tutorial.index.json`,
which meant that they could only be rendered if you browsed to `/tutorial/index`.
This didn't sit well so now these pages are mapped to `tutorial.json`, which
means that you browser to them via `/tutorial/` or just `/tutorial`.
Fixed#15335
For some reason the tree-shaker is not picking up these interfaces
(perhaps TS is not passing it through) when they are in the same file
as their related services. This results in a distracting warning message.
There is a weirdness in the Angular Location service.
If the `baseHref` is only a single slash (`'/'`) then it
changes it to be an empty string (`''`). The effect of this
is that `Location.normaliseUrl(url)` does not strip off the
leading slash from url paths.
The problem is that the leading slash only appears on the
initial Location path, and not on urls that arrive from subscribing
to the Location service.
This commit is a workaround this problem.
