Integrate Arrays into your Firestore Database

Is there a way to retrieve an array from Firestore? https://i.sstatic.net/k69Py.png

For instance, when dealing with a simple field I would use [(ngModel)] ="proyecto.titulo", but how would I input data into an array in this scenario?

Answer №1

To store an array in the database, you can use the code

db.doc("documentName.tags").set(["tag1", "tag2", "tag3"])

This method will create the desired structure for your data.

Alternatively, it is recommended to save the array as a map with index values such as 0, 1, 2, .... This way, you can easily reference and update individual elements using commands like

db.doc("documentName.tags.0").set("new tag1")
