While you wait for better answers, it might be worth investigating to see if the problem persists when using Angular’s HttpClient instead of the plugin one.

CSS keyframe animation on ion-item is not transitioning smoothly
I think you’ve hit the nail on the head here. It’s pretty obvious that the issue lies with Ionic’s Web Components and that is why you’re experiencing a difference in animation VS plain HTML.
So just use plain HTML and CSS where you need to and avoid Web Components.

This scope inside a callback
WOW, this is a dense answer!!! I’m not familiar with Factory but I looked it up and it seemed just like a class implementing an interface, so I implemented it and now the only dependency of the Home component is the NetworkProvider, which is nice. So far I have the following
network-provider.ts
export interface Host {
addr: string;
start(): void ;
send(dest:string, msg:string): void;
receive: Function;
getActivities():Observable<string>;
}
...
class HostFactory implements Host {
public addr:string;
public receive: Function = null;
public net: NetworkProvider; //network that created the host
constructor(addr:string) { this.addr=addr; }
start(){
this.net.join(this.addr).subscribe((p:Packet) => {
if (p) {
this._activitie$.next("R-"+p.sa+":"+p.da+":"+p.payload); //log activities for curious folks
if (this.receive) {
this.receive(p); //call host receive handler
}
}
});
...
@Injectable()
export class NetworkProvider {
public createHost(addr:string): Host {
let h = new HostFactory(addr);
h.net = this;
return h;
}
home.ts
import { NetworkProvider, BroadcastAddress, Host, Packet } from '../../providers/network-provider';
@Component({...})
export class HomePage {
clientA:Host;
server:Host;
constructor(public net:NetworkProvider...) {
this.clientA = net.createHost('AA');
this.clientA.receive = (p:Packet) => { this.clientReceiveMachine(this.clientA, p); }
this.server = net.createHost('55');
this.server.receive = (p:Packet) => { this.serverReceiveMachine(this.server, p); }
}
clientReceiveMachine(h:Host, p:Packet) {
console.log('Rcvd.hAddr:'+h.addr+' sa:'+p.sa+' da:'+p.da+' p:'+p.payload);
}
serverReceiveMachine(h:Host, p:Packet) {
console.log('Rcvd.hAddr:'+h.addr+' sa:'+p.sa+' da:'+p.da+' p:'+p.payload);
if (p.payload==='Hello') {
h.send(p.sa, "HelloBack");
}
}
Even though it works fine, there’s a few things leaving me uncomfortable:
- in order for the host to send and receive packets, it needs a reference to the network, so I set it with this in
createHost--> doesn’t feel right - clients and servers need a different logic when receiving packets so I use a receive:Function property on the interface --> can be seen as a handler but too similar to callbacks to feel comfortable
So once again, I’m sure there is a better way.

This scope inside a callback
No, it’s a singleton that spawns things.
I’m assuming for now that there is only a single Network. To deal with multihomed Hosts, you would have to convert addr into a list of addr/network pairs.
// this does not deal with multihomed hosts atm
export interface Host {
addr: string;
packets$: Observable<Packet>;
activities$: Observable<string>;
}
@Injectable()
class HostFactory {
constructor(private net: NetworkProvider) {}
createHost(addr: string): Host {
let rv = {addr} as Host;
rv.packets$ = this.net.join(addr);
rv.activities$ = rv.packets$.pipe(
map(pkt => `R-${p.sa}:${p.da}:${p.payload}`));
return rv;
}
// if needed, but i would try to make it not needed
disposeHost(host: Host): void {
this.net.unjoin(addr);
}
}
@UntilDestroy()
class HomePage {
clientA: Host;
server: Host;
constructor(private hoster: HostProvider, private net: NetworkProvider) {
this.clientA = hoster.createHost("AA");
this.clientA.packets$.pipe(untilDestroyed(this))
.subscribe(pkt => this.clientReceiveMachine(this.clientA, pkt));
this.server = hoster.createHost("55");
this.server.packets$.pipe(untilDestroyed(this))
.subscribe(pkt => this.serverReceiveMachine(this.server, pkt));
}
serverReceiveMachine(h: Host, p: Packet) {
console.log('Rcvd.hAddr:'+h.addr+' sa:'+p.sa+' da:'+p.da+' p:'+p.payload);
if (p.payload==='Hello') {
this.net.send({sa: h.addr, da: p.sa, payload: "HelloBack"});
}
}
}
Solved by not having hosts send and receive packets. The network does that.
Not something Host should concern itself with. Done as shown above by changing what you do when you subscribe to the packet stream coming into that Host (or derivative thereof such as activities$). All Hosts do is effectively filter all the packets on the network down to the ones where da matches that Host's addr.

How to set value dynamically default value in ion-select-option

Why ionic creat does't care about customer?
Are you an Enterprise User?
I think they are doing their best to answer everything.
Ionic3 is working, but not supported 100% anymore. You should update your Version to ionic 5. On the one side for you and for a guaranteed Support, but on the other Side for your Users too, as the latest Versions include the latest native Styles and clearly works better.
And of course you can create the native APK & IPA Files directly? For Example ionic cordova build android builds a native Android APK.
