Package Type Update Change
leptos dependencies minor 0.6.15 -> 0.8.0

Release Notes

leptos-rs/leptos (leptos)

v0.8.6

Compare Source

Just a patch release, mostly to support #[server] #[lazy] for lazy server functions.

Going forward, patch releases for various crates will have version numbers that are not coupled to one another, and will only be bumped when they've actually changed; so this release is 0.8.6 for leptos, leptos_macro, and server_fn_macro, but does not arbitrarily bump other packages that haven't changed.

See 0.8.5 for notes on WASM splitting.

v0.8.5: : WASM code splitting released!

Compare Source

This release includes WASM code-splitting/lazy-loading support, in tandem with the latest cargo-leptos release.

You can use the lazy_routes example to understand what this means!

Essentially, though, there are two patterns:

  1. Use the #[lazy] macro to make any given function lazy
  2. Use the #[lazy_route] to designate a route with a lazy-loaded view, which is loaded concurrently with the route's data

#[lazy] converts a (sync or async) function into a lazy-loaded async function

#[lazy]
fn deserialize_comments(data: &str) -> Vec<Comment> {
    serde_json::from_str(data).unwrap()
}

#[lazy_route] lets you split routes into a "data" half and a "view" half, which will be concurrently loaded by the router. This works with nested routing: so if you have ViewD and ViewE, then the router will concurrently load D's data, D's (lazy) view, E's data, and E's (lazy) view, before navigating to the page.

struct ViewD {
    data: Resource<Result<Vec<i32>, ServerFnError>>,
}

#[lazy_route]
impl LazyRoute for ViewD {
    fn data() -> Self {
        Self {
            data: Resource::new(|| (), |_| d_data()),
        }
    }

    fn view(this: Self) -> AnyView {
        let items = move || {
            Suspend::new(async move {
                this.data
                    .await
                    .unwrap_or_default()
                    .into_iter()
                    .map(|item| view! { <li>{item}</li> })
                    .collect::<Vec<_>>()
            })
        };
        view! {
            <p id="page">"View D"</p>
            <hr/>
            <Suspense fallback=|| view! { <p id="loading">"Loading..."</p> }>
                <ul>{items}</ul>
            </Suspense>
            <Outlet/>
        }
        .into_any()
    }
}

#[server]
async fn d_data() -> Result<Vec<i32>, ServerFnError> {
    tokio::time::sleep(std::time::Duration::from_millis(250)).await;
    Ok(vec![1, 1, 2, 3, 5, 8, 13])
}

Our whole July stream was dedicated to the topic, if you want more in depth discussion.

v0.8.4

Compare Source

There are some small bugfixes in here, as well as improvements to the hot-reloading code. This is mostly intended to be a sort of "last patch" before merging the code-splitting changes in #​3988, so that there is a patch people can pin to in case those inadvertently introduce any regressions.

v0.8.3

Compare Source

This is a minor patch release. It does include a significant re-write of how ownership/context work with nested routes (#​4091). This should close a number of bugs. However, it's always possible that changes like this introduce regressions. Please test to see whether you have any issues with context and nested routing, and let me know. (We have a new regression example set up to add e2e regression tests for issues going forward.)

*Changelog relative to 0.7.8. *

0.8 has been planned for a while, primarily to accommodate small changes that arose during the course of testing and adopting 0.7, most of which are technically semver-breaking but should not meaningfully affect user code. I think it's a significant QOL and user DX upgrade and I'm excited to properly release it.

Noteworthy features:

  • Axum 0.8 support. (This alone required a major version bump, as we reexport some Axum types.) (thanks to @​sabify for the migration work here)
  • Significant improvements to compile times when using --cfg=erase_components, which is useful as a dev-mode optimization (thanks to @​zakstucke) This is the default setting for cargo-leptos with its latest release, and can be set up manually for use with Trunk. (See docs here.)
  • Support for the new islands-router features that allow a client-side routing experience while using islands (see the islands_router example) (this one was me)
  • Improved server function error handling by allowing you to use any type that implements FromServerFnError rather than being constrained to use ServerFnError (see #​3274). (Note: This will require changes if you're using a custom error type, but should be a better experience.) (thanks to @​ryo33)
  • Support for creating WebSockets via server fns (thanks to @​ealmloff)
  • Changes to make custom errors significantly more ergonomic when using server functions
  • LocalResource no longer exposes a SendWrapper in the API for the types it returns. (Breaking change: this will require removing some .as_deref() and so on when using LocalResource, but ends up with a much better API.)
  • Significantly improved DX/bugfixes for thread-local Actions.

As you can see this was a real team effort and, as always, I'm grateful for the contributions of everyone named above, and all those who made commits below.

WebSocket Example

The WebSocket support is particularly exciting, as it allows you to call server functions using the default Rust Stream trait from the futures crate, and have those streams send messages over websockets without you needing to know anything about that process. The API landed in a place that feels like a great extension of the "server function" abstraction in which you can make HTTP requests as if they were ordinary async calls. The websocket stuff doesn't integrate directly with Resources/SSR (which make more sense for one-shot things) but is really easy to use:

use server_fn::{codec::JsonEncoding, BoxedStream, ServerFnError, Websocket};

// The websocket protocol can be used on any server function that accepts and returns a [`BoxedStream`]
// with items that can be encoded by the input and output encoding generics.
//
// In this case, the input and output encodings are [`Json`] and [`Json`], respectively which requires
// the items to implement [`Serialize`] and [`Deserialize`].

#[server(protocol = Websocket<JsonEncoding, JsonEncoding>)]
async fn echo_websocket(
    input: BoxedStream<String, ServerFnError>,
) -> Result<BoxedStream<String, ServerFnError>, ServerFnError> {
    use futures::channel::mpsc;
    use futures::{SinkExt, StreamExt};
    let mut input = input; // FIXME :-) server fn fields should pass mut through to destructure

    // create a channel of outgoing websocket messages 
    // we'll return rx, so sending a message to tx will send a message to the client via the websocket
    let (mut tx, rx) = mpsc::channel(1);

    // spawn a task to listen to the input stream of messages coming in over the websocket 
    tokio::spawn(async move {
        while let Some(msg) = input.next().await {
            // do some work on each message, and then send our responses 
            tx.send(msg.map(|msg| msg.to_ascii_uppercase())).await;
        }
    });

    Ok(rx.into())
}

#[component]
pub fn App() -> impl IntoView {
    use futures::channel::mpsc;
    use futures::StreamExt;
    let (mut tx, rx) = mpsc::channel(1);
    let latest = RwSignal::new(None);

    // we'll only listen for websocket messages on the client
    if cfg!(feature = "hydrate") {
        spawn_local(async move {
            match echo_websocket(rx.into()).await {
                Ok(mut messages) => {
                    while let Some(msg) = messages.next().await {
                        latest.set(Some(msg));
                    }
                }
                Err(e) => leptos::logging::warn!("{e}"),
            }
        });
    }

    view! {
        <input type="text" on:input:target=move |ev| {
            tx.try_send(Ok(ev.target().value()));
        }/>
        <p>{latest}</p>
    }
}
