Here my situation.
Right now, before pushing another page, I am doing 3x http calls done by 3 different services. They all return promises then, I push the next page
One service looks like
return new Promise((resolve, reject) => {
this._http.get(url)
.map(res => res.json())
.subscribe(
data => {
this._itemsList = data.itemsList;
resolve(this._itemsList);
},
error => {
console.log("Error to get items list");
reject("Error to get items list");
}
)
});
In the .ts file that calls all the http looks like
this._itemService.retrieveItemsData()
.then((success) => { return this._gService.retrieveGData(); })
.then((success) => { return this._cService.retrieveCData(); })
.then((success) => this._nav.push(DashboardPage));
}
I know the http request returns an Observable, but I don’t know much about it and don’t know if it is possible to call all those http and then call the nav.push. If so, how do you do that?
Thanks
