Manage State

The state object passed to your page function can be read and updated to manage the state of your application. By default it's a dictionary.

Notice how the we access the message from the first page in the second page.

@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
