As per suggestion on Firebase documentation on Firestore bundles, I haven’t found the best way to create bundle based on the example given above. I don’t know what I have to include in
docSnapshot. I know what I have to fill in collection. But what is the case if CollectionGroup? There is no detail explanation about it, either. Can someone from Firebase team explain what I have to include in
docSnapshot? I have collection "Music_Epic", for example?
const bundleId = "latest-Epic"; const bundle = firestore.bundle(bundleId); const docSnapshot = await firestore.doc("Music_Epic/").get(); //What should be here? const querySnapshot = await firestore.collection("Music_Epic").get(); // Build the bundle // Note how querySnapshot is named "latest-stories-query" const bundleBuffer = bundle.add(docSnapshot); // Add a document bundleBuffer.add("latest-Epic-query", querySnapshot); // Add a named query. bundleBuffer.build();
add() takes either a
(queryName, QuerySnapshot) as parameters. Collection Groups queries also return a
QuerySnapshot so you can follow the same method used for querying a single collection.
const bundle = firestore.bundle(); const querySnapshot = await firestore.collection("Music_Epic").get(); // For collectionGroup queries: // const querySnapshot = await firestore.collectionGroup("col_name").get(); const bundleBuffer = bundle.add('latest_music_epic_query', querySnapshot); bundleBuffer.build();
