CSR and Full Stack

[sam-rusty]

Hi everyone! I'm trying to build a decoupled fullstack app sharing code between frontend and backend, but deployed separately:

Frontend: Pure CSR static files on Cloudflare Pages.

Backend: API/Server Functions on AWS ECS.

I adapted examples/07-fullstack/desktop for the web. When I build the frontend (dx bundle --web --release) and serve it statically (bunx serve .), it crashes in the browser:

Uncaught InvalidCharacterError: Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded.

It's looking for window.initial_dioxus_hydration_data (SSR), but I'm serving a static HTML file so it evaluates to undefined.

Cargo.toml

[dependencies]
dioxus = { workspace = true, features = ["fullstack"] }
serde = { workspace = true }

[features]
server = ["dioxus/server"]
web = ["dioxus/web"]

main.rs

use dioxus::prelude::*;

fn main() {
    #[cfg(not(feature = "server"))]
    dioxus::fullstack::set_server_url("http://127.0.0.1:8080");
    dioxus::launch(app);
}

pub fn app() -> Element {
    let mut text = use_signal(|| "...".to_string());
    rsx! {
        button {
            onclick: move |_| async move {
                if let Ok(data) = get_server_data().await { text.set(data); }
            },
            "Run server function"
        }
    }
}

#[get("/api/data")]
async fn get_server_data() -> ServerFnResult<String> {
    Ok("Hello!".to_string())
}

Question:
How do I configure the Dioxus CLI to build a pure CSR client that doesn't expect SSR hydration data, while keeping the fullstack feature enabled so #[server] macros and client fetches still work? Any guidance would be hugely appreciated!
