I'm building an experimental (Ionic 2) app that uses Firebase and AngularFire2 (currently in alpha). For this I'm following this tutorial from Aaron Saunders as a basis: [LINK] [LINK] Below are my home.ts and my home.html. this.projects = af.list('/items').map( (items) => { return items.map( item => { item.meta = af.object(`/item_meta/${item.$key}`) return item }) }) This way of nesting the Observables returns by AngularFire2 was demonstrated in the following presentation: [this video] Here is my view: <ion-card *ngFor="#item of items | async"> <ion-card-header> {{item.name}} </ion-card-header> <ion-card-content> {{item.description}} <br> {{item.meta.stockPrice | async}} </ion-card-content> </ion

I am trying to build a webpage using angular2, Firebase 3 SDK and angularfire2. I have recently gotten to all of these frameworks or SDKs. So I have some difficulties understanding all the functions in files like systemjs.config, typings.json, tsconfig.json,packages.json and etc. I think for now I got some understanding about these files, but I'm not confident enough to configure all of them for my project.

I think you can get the data as the original snapshot by specifying the preserveSnapshot option as described here: Retrieving the snapshot [LINK] and then iterate as you need. let myItems = []; let orderItems = this.af.database.list('/order_items', { preserveSnapshot: true } ); this.orderItems.subscribe((itemKeys) => { itemKeys.forEach((itemKey) => { let item = this.af.database.object('/items/'+itemKey.key); item.subscribe((itemData) => { myItems.push(itemData); }); }); }) I think you could also map the items with the keys to order_items right away, something like here: AngularFire for Angular 2 [this video] , but I am not sure how to do this, since I am new to ng2, af2 and firebase.

I am getting a list with ID's and i want to get the object with that ID const path = `/lists/${auth.$uid}`; this.lijsten = map.call(af.database.list(path), (vals: any[]) => { return vals.map((m) => { m.shapes = af.database.object(`/lists/${m.$key}`); return m; }); }); This doesn't work for an extra firebase call. The call works, but it can't convert to JSON. If I replace it for a String, it works. I got this example from the youtube video from angular [this video] But when i use this example i can't convert it to json lijsten | async | json gives Converting circular structure to JSON at JSON.stringify () Is there a better w
