Can you guys merge this PR? Or if there is a problem tell me.

Not sure if this is the best method for grabbing documents from a collection.

getDocs(collection(this.firestore, "data")).then( (querySnapshot: QuerySnapshot) => { this.items = []; querySnapshot.forEach((doc: any) => { this.items.push(doc.data()); }); } );

I ended up with something like

getItemsFromCollection(): Observable<Items[]> { const collectionRef = collection(this.firestore, "data"); return collectionData(collectionRef) as Observable<Items[]>; }

Then subscribed to this via the component

So can you implement it in the docs? Open a PR in my repo and I will pull it.

I'm doing the same and it's working fine here.

thank you so much

Started working on remote config.

@jamesdaniels can you merge this or tell me if there are some problems.

I think we're going to steer clear of long form content on this repository, instead aim only for reference docs.

I think this would be great for a blog post, we could potentially link to "other resources" in the README, & amplify if you take a pass at hosting this on medium or somewhere.
