Hi list, hi Marcos,
I started updating webph.one to Angular 5. My work in progress can be
viewed at github.com:ekroymann/webph.one.git.
I started with following the instructions at
https://angular-update-guide.firebaseapp.com/w. This is mostly done. There
are some new optional features, which we might want to start using. I did
not get into this yet.
It seems, that the material design dependencies still need to be upgraded,
since when compiling I get warnings about incompatibility.
However, the main problem is the service worker used for push. The previous
implementation relied on extending @angular/service-worker@^1.0.0-beta.16,
a pretty old version as we can see. This version is not compatible anymore
with Angular 5. The new version of @angular/service-worker has a completely
different interface and also does not allow extension anymore. The
extension of the previous version implemented receiving the push
notification and displaying a notification to the user. The new version of
@angular/service-worker comes with a generic service worker, that has built
in support for receiving push notfications and displaying notifications to
BUT: this relies on the backend sending a notification payload to be
displayed as is in the push notification.
We now have two options: either implementing the ServiceWorker completely
our selves and not using @angular/service-worker, or changing the backend
to include the notification payload in the push notifications.
I can work on this, but I wanted to know what is the preferred way to go
forward. I think, when changing the backends, we will have some problems
with testing, since we need a new version of the backend deployed
somewhere, along with the old version of the backend for the previous
versions of the app.
What is your opinion?
