dx-utils

Utility components and functions for Dioxus fullstack apps.

Components

LocalTime

Renders an RFC 3339 datetime string as a <time> element in the browser's local timezone.

• During SSR: displays UTC (e.g. 2025-06-15 14:30).
• On the client (post-hydration): use_effect + js_sys::Date converts to the browser's local timezone. No JavaScript eval or global scripts.

Props:

use dioxus::prelude::*;
use dx_utils::LocalTime;

#[component]
fn UsageRow(hour_bucket: String) -> Element {
    rsx! {
        td { LocalTime { datetime: hour_bucket } }
    }
}

Functions

redirect_external(url: &str)

Redirect to an external URL. Works correctly during both SSR and client-side navigation.

• During SSR: sets HTTP 302 status and a Location header via FullstackContext, producing a real HTTP redirect before any HTML reaches the browser.
• On the client (post-hydration): uses navigator().replace() with NavigationTarget::External for a client-side navigation.

use dioxus::prelude::*;
use dx_utils::redirect_external;

#[component]
fn AuthGuard() -> Element {
    let auth = use_server_future(|| check_auth())?;
    let binding = auth.read();
    let status = binding.as_ref().and_then(|r| r.as_ref().ok());

    if let Some(s) = status {
        if !s.authenticated {
            redirect_external(&s.login_url);
            return rsx! {};
        }
    }

    rsx! { Outlet::<Route> {} }
}
