Fetching all collections in Firestore

Question

I am using Firestore in my project, so i want to show all collection names in my project.

Is it posible to get all collection names from Firebase project.

Thanks..

Answer 1

There are limited public APIs to get a list of top-level collections. Mobile clients (Android, iOS, web) have no API. Node.js admin clients have listCollections() on Firestore to get that list. Or, if you're looking for subcollections nested under a document, use DocumentReference.listCollections().

If you want to get a list on any platform, you should maintain that list yourself in a known collection inside a known document id.

Answer 2

You can do the following:

const admin = require("firebase-admin"); const db = admin.firestore();  db.listCollections()   .then(snapshot=>{       snapshot.forEach(snaps => {         console.log(snaps["_queryOptions"].collectionId); // LIST OF ALL COLLECTIONS       })   })   .catch(error => console.error(error));  

This works with NodeJS.
Remember that you will need to download firebase-admin and do the necessary configuration for Firebase server side.
