Subscribe will be deprecated. The example I have seen on the RxJS website don't really use any observers. If I remove subscribe from the following code, I get "error TS2349: This expression is not callable. [ng] Type 'Observable' has no call signatures."
if (this.postData.token) {
this.feedService.feedData(this.postData).subscribe(
(res: any) => {
this.feedService.changeFeedData(res.feedData);
},
(error: any) => {
this.toastService.presentToast('Error!');
}
);
}
The subscribe()
method itself is not deprecated. The RxJS team just deprecated the signatures that take multiple arguments, mostly because of readability concerns.
Instead, they'd like you to write:
if (this.postData.token) {
this.feedService.feedData(this.postData).subscribe({
next: (res: any) => {
this.feedService.changeFeedData(res.feedData);
},
error: (error: any) => {
this.toastService.presentToast('Error!');
}
});
}
