Firestore - OrderBy won't work if placed inside return code

Question

I want to order my data by "Time", but whenever i try to add .orderby("time"), it displays an error.

My Get function"

return this.firestore.collection('East_Area').snapshotChanges();

I tried doing this:

return this.firestore.collection('East_Area').orderBy("time").limit(3).snapshotChanges();

Am i doing something wrong? Any help would be appreciated!

Answer 1

Change this:

return this.firestore.collection('East_Area').orderBy("time").limit(3).snapshotChanges();

into this:

do this then: return this.firestore.collection('East_Area', ref => ref.orderBy("time")).snapshotChanges()

snapshotChanges() is a method inside angulareFire but you are using plain javascript, therefore you need to use get() method to retrieve data.
