Is there a method to iterate through all documents in a collection in firestore

Question

I\'m using the firestore of firebase and I want to iterate through the whole collection. Is there something like:

db.collection(\'something\').forEach((doc) =>         


        

Answer 1

Yes, you can simply query the collection for all its documents using the get() method on the collection reference. A CollectionReference object subclasses Query, so you can call Query methods on it. By itself, a collection reference is essentially an unfiltered query for all of its documents.

Android: Query.get()

iOS/Swift: Query.getDocuments()

JavaScript: Query.get()

In each platform, this method is asynchronous, so you'll have to deal with the callbacks correctly.
