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
}
💡
idof object is always the same to its globalvarso 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);
