I am looking to adjust this function so that it sends these two file ids in separate requests:
return this.upload(myForm).pipe(
take(1),
switchMap(res => {
body.user.profilePic = res.data.profilePic;
body.user.coverPic = res.data.coverPic;
return this.http.post<IRresponse<object>>(environment.api + EndPoint.CreateUser, body);
})
);
Would using flatmap be a good option here?
If you want to make separate requests using one pipe, you can structure it like this:
return this.upload(myForm).pipe(
take(1),
switchMap(res => {
body.user.profilePic = res.data.profilePic;
body.user.coverPic = res.data.coverPic;
return [
this.http.post<IRresponse<object>>(environment.api + EndPoint.CreateUser, body),
this.http.post<IRresponse<object>>(environment.api + EndPoint.CreateUser, body),
]
}),
mergeAll(),
);
Choosing the appropriate operator depends on whether you prefer to send the two requests concurrently or sequentially.
If you already have take(1), then you can opt for either switchMap or mergeMap since it will only emit once regardless of the choice.
For parallel request sending:
return this.upload(myForm).pipe(
take(1),
switchMap(res => {
...
return forkJoin([
this.http.post<IRresponse<object>>(environment.api + EndPoint.CreateUser, body),
this.http.post<IRresponse<object>>(environment.api + EndPoint.CreateUser, body),
]);
}),
);
For sequential request sending:
return this.upload(myForm).pipe(
take(1),
switchMap(res => {
...
return concat(
this.http.post<IRresponse<object>>(environment.api + EndPoint.CreateUser, body),
this.http.post<IRresponse<object>>(environment.api + EndPoint.CreateUser, body),
);
}),
);
