Storing Classes and Objects

Class
First thing first, classes require to be registered before used in Nucleoid:
class Order {
constructor(item, qty) {
this.item = item;
this.qty = qty;
}
}
nucleoid.register(Order);
Objects
The same thing for objects, once initiated and assigned to the var
variable as well as it stored.
app.post("/orders", () => {
var order = new Order("ITEM-123", 3);
return order;
});
and it can retrieve by its var
variable as mentioned earlier.
app.get("/orders", () => {
return order;
});
{
"id": "order0",
"item": "ITEM-123",
"qty": 1
}
if object initiated without assigning var
variable, the runtime automatically assign var
variable along with id
app.post("/test", () => new Order("ITEM-123", 3));
{
"id": "order0",
"item": "ITEM-123",
"qty": 1
}
💡
id
of object is always the same to its globalvar
so that either can be used to retrieve the object like
Order["order0"]
andorder0
.
if object assigned to either let
or const
, the runtime will create var
variable the same as its id
app.post("/orders", () => {
const order = new Order("ITEM-123", 3);
return order;
});
{
"id": "order1",
"item": "ITEM-123",
"qty": 1
}
Now, it can use its id
as var
in order to retrieve the object
app.get("/test", () => order1);
