QUESTION
How to get Capacitor Storage values before doing http call IONIC 6
Asked 2022-Mar-18 at 07:19I've been looking for a tutorial on how to get some values I have on my Capacitor Storage in Ionic 6 and use them before doing the HTTP request.
Example method in cart.service.ts:
getCart() {
Storage.get({ key: 'token' }).then( response => {
this.token = JSON.parse(response.value);
});
return this.http.get<Product[]>(this.token.api_route + 'user/cart');
}
What I want to call on onInit:
this.cartService.getCart().subscribe(response => {
this.products = response;
});
So the main problem is that token is null because getting it from storage is async. How can I solve that problem? And get the token.api_route before doing HTTP call?
ANSWER
Answered 2022-Mar-18 at 07:19Use a promise instead of an observable. You could use http.get(url).toPromise() to achieve that.
Here is an example:
import { Component } from '@angular/core';
import { Storage } from '@capacitor/storage';
import { HttpClient } from '@angular/common/http';
@Component({
selector: 'app-home',
templateUrl: 'home.page.html',
styleUrls: ['home.page.scss'],
})
export class HomePage {
html = 'hello';
constructor(public http: HttpClient) {}
async test() {
await this.saveToStorage();
this.problem();
}
async saveToStorage() {
console.log('Saving something to local storage...');
await Storage.set({
key: 'url',
value: 'https://jsonplaceholder.typicode.com/posts',
});
}
problem() {
this.getApiValue().then((value) => {
this.html = JSON.stringify(value) ;
});
}
async getApiValue() {
const urltogo = await Storage.get({key:'url'});
return this.http.get(urltogo.value).toPromise();
}
}
