VisualizaçõesImpossible to use res.name because of subscribe (ANGULAR)
Currently I am following a tutorial on Youtube in which it uses authentication with Angular and I can't continue at this point :
His code does not work on my side because of subscribe() which gives me the message:
@deprecated — Instead of passing separate callback arguments, use an observer argument. Signatures taking separate callback arguments will be removed in v8. Details: https://rxjs.dev/deprecations/subscribe-arguments
I'm forced to use next, error and complete and and despite everything, the res.name is not displayed.
ngOnInit(): void {
this.http.get(
'http://localhost:8080/api/user',
{withCredentials: true}
).subscribe({
complete: () => { (res: any) => this.visiteur = `${res.nom}` },
error: () => { (err: any) => console.log(err) },
next: () => { (res: any) => this.visiteur = `${res.nom}` }
});
}

The current way of subscribing is using more of rxjs operators, The tutorial you are following seems a little outdated. I recommend you follow angular's Tour of heroes tutorial instead. It is always up-to-date.
This should get you going:
this.http
.get('http://localhost:8080/api/user')
.pipe(
catchError(err => {
console.log(err);
})
)
.subscribe(data => {
this.visiteur = `${data.nom}`;
});
Also I would recommend you implement an angular http interceptor to pass in http required attributes/headers (in your case withCredentials). But this is optional for the scope of this question.
And finally, don't forget to avoid the memory-leak trap with subscriptions.
