Hi, > please help me and guide me what i am doing wrong
I just took a quick look into your gist: It looks like you want to aggregate your data by "createdAt" at the first level. If so, it might makes sense to start with the date within your key: emit(["createdAt", "outletId", "name"], ...) BTW 1: You might want to use "createdAt.substring(0,10)" in order to extraxt the date instead of invoking "Date()" a couple of times. BTW 2: "outletId" seems to be not part of your document at your gist. Maybe this helps, Olaf
