Grimoire Tutorial: Getting Started

Custom State Class

Dictionaries are cool, but often a custom class will make writing our code much more enjoyable. You can add a custom state class when creating your app.

from dataclasses import dataclass


@dataclass
class State:
    message: str = ""


app = Grimoire(State)


@app.page(start=True)
def start(state, second):
    state.message = "Hello, traveller"
    return Div(
        P("Hello, Grimoire!"),
        Ul(Li(link("Go to the second page", second)))
    ), state


@app.page()
def second(state):
    return Div(
        P(f"message: {state.message}")
    ), state
