Firebase Order Processing

Order processing in a firebase database.

Database structure

• Users, Products, Orders
• Data is structured as 3 seperate entities
• No IDs will be stored in the entities themselves
• Firebase will auto generate all IDs

    "name": "John Smith",
    "email": "john@smith.com"
}

Products

{
    "name": "Item1",
    "amount": "399",
    "currency": "gbp"
}

Orders

{
    "userID":  "<firebase-generated-user-id>",
    "productID": "<firebase-generated-product-id>",
    "payment": {
        "cvc": "222",
        "object": "card",
        "exp_month": "10",
        "exp_year": "2020",
