Your question is not clear. Do you want to know how to fetch values from your JSON such as purchasereturns and shipping in Angular 6?

ok let me explain my issue sir. 
i send order details with purchase details as null.Order is a collection . order :{ "orderId":1, "material": "bags", "quantity": 10, "purchase": {....} }
 because have another form for purchase so later i can update to paricular order. so purchase details can have multiple. purchase { 1: {"id":11, "material" : "bags "},
                              2: {"id":12, "material" : "bags " }
                            }
for this before to read data first i have to send my purchase details so i need to call update with order collection rite. how to do that? sir

Are you using same JSON format to update the purchase?
You can use Angular HttpClient.put() for update operation.

httpClient is for real time database, but am using firestore.
