I think it is possible to add an HTTP header that specify that the cache should expire after a certain amount of time 👍

Hello Carl! they are differents (for differents uses) and will exist on separate repos 👍 For example ui-html is easy and can be just "buttons a loop" but is for a single user app, the other (this one) is more for classes ("components") to compose larger things but is for multiple separate users, each users have a live connection (with websockets) and their own states (instances of structs). It is a little bit like a web framework with the states on the server. I'd like to keep ui-html self contained with zero dependencies so people can do anything with it, for the other one, not sure yet but i thought about it too (🥳 lightbug backend) 👍 One of the big idea for what i'd like it to be, is to move from PythonObject to Object eventually !

Passing method references to high-order functions
Hello @Manuel Saelices, here is an example with parameters: 
@value
struct Foo:
    fn myfunc(self) -> Int:
        return 42

# Note: capturing [_] for lifetimes/origin !
fn high_order_func[f: fn () capturing [_] -> Int]() -> Int:
    return f()

fn main():
    foo = Foo()
    
    @parameter
    fn foo_myfunc() -> Int:
        return foo.myfunc()

    #__type_of(foo).__del__(foo^)
    print(high_order_func[foo_myfunc]())
@value
struct Foo:
    fn myfunc(self) -> Int:
        return 42

# Note: capturing [_] for lifetimes/origin !
fn high_order_func[f: fn () capturing [_] -> Int]() -> Int:
    return f()

fn main():
    foo = Foo()
    
    @parameter
    fn foo_myfunc() -> Int:
        return foo.myfunc()

    #__type_of(foo).__del__(foo^)
    print(high_order_func[foo_myfunc]())

Hello, here is an additional way: 
from random import random_ui64, seed
def main():
    seed()
    for _ in range(10):
        var x: UInt8 = random_ui64(0, 255).cast[DType.uint8]()
        print(x)
from random import random_ui64, seed
def main():
    seed()
    for _ in range(10):
        var x: UInt8 = random_ui64(0, 255).cast[DType.uint8]()
        print(x)
Note: Documentation: random for more functions (rand and randn for different distributions (normal/uniform), for example)

The idea is: "The back-end and the front-end in the same structs!" It works with websockets, a Dict is on the server for visitors states, that way, less complixity 👍 Doing it that way removes the need for creating rest API, events are sent trough websockets, which is the session, and server send a dom-tree as json then the browser just render it.

Is there a disdain for Rust from the Mojo team?
It would not make sense to move lifetimes out of the parameter world, because things can be parametrized on lifetime, and lifetimes can be parametrized. As a superset of python, mojo have theses [] for generics(parametrization), that's all there is to it really 👍

It is just about parameters (you'll see as you read). There is also that thing called progressive exposure to complexity, i like that there is a progressive way of learning as you build/create, and it requires consistent choices that makes sense: (note how lifetimes are parameters, and how lifetimes can also be parametrized on mutability)

Working on it 🔥 ! already have the connection upgrade to websocket and the ability to receive messages of all sizes ! It is quite difficult to implement all the features (fragments) and many things could raise. Let's focus on an example that can do receive and send. We might need to get on an audio conference and adapt it to lightbug 👍 Documentation: https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#the_websocket_handshake
Would you mind if i PR a websocket.mojo to lightbug in a work_in_progress folder? (That way you can scavage the example and integrate to lightbug)
