Getting all documents from one collection in Firestore

Question

Hi I\'m starting with javascript and react-native and I\'m trying to figure out this problem for hours now. Can someone explain me how to get all the documents from firestor

Answer 1

I prefer to hide all code complexity in my services... so, I generally use something like this:

In my events.service.ts

    async getEvents() {
        const snapchot = await this.db.collection('events').ref.get();
        return new Promise  (resolve => {
            const v = snapchot.docs.map(x => {
                const obj = x.data();
                obj.id = x.id;
                return obj as Event;
            });
            resolve(v);
        });
    }

In my sth.page.ts

   myList: Event[];

   construct(private service: EventsService){}

   async ngOnInit() {
      this.myList = await this.service.getEvents();
   }

Enjoy :)
