v0.4.5

I've gotten back into a regular rhythm of patch releases pulling in some of the smaller bugfixes, but haven't had time to write release notes for each one. I should just auto-generate them, I suppose—sorry about that!

Anyway here's a quick summary of the new features included in the past few releases. The full changelog below includes various bugfixes, chores, and updates to the docs as well.

• Some useful fixes to support for cargo leptos watch --hot-reload
• leptos_axum::extract_with_state to support extractors that use a State, if it's been provided via context in a custom handler
• The watch function, which functions as a more configurable create_effect, including the ability to explicitly list dependencies, stop listening to them, whether to run immediately or lazily, etc.
• Better 404 page support in Actix examples and templates
• Added support for adding Content-Security-Policy nonces to inline script and style tags with use_nonce and the nonce feature
• Rewritten <For/> diffing algorithm that both fixes a number of correctness issues/edge cases in <For/> and drops ~10kb from the WASM binary

Basically, a bunch of small but really useful changes, and about a hundred bugfixes.

I also just want to give a shout-out to @agilarity, who's become one of the top contributors to the library through a very helpful focus on CI and testing. If you're ever looking for a great model of how to test a Leptos frontend app, the counters_stable example now features two complete test suites, one in JS using Playwright and one written in Rust using wasm_bindgen_test. This has been a huge amount of very impressive work.

`v0.4.0`

v0.4.0

Enough bugfixes and features have accumulated in the main branch that it's time for a new release. However, a very early change meant this needs to be a semver bump. Rather than continuing the confusion of the feature/bug gap between 0.3.1 and main, this releases the current state of the main branch.

I was actually surprised, putting together these release notes, how much good stuff there is in here that I'd forgotten was new to this release!

This does not include the reactive ownership rewrite (#918), which I'd guess will be 0.5. But it does include the following...

Breaking Changes

• leptos_axum now uses the (more common, more type-safe, more extensible) State and sub-state patterns rather than Extension to pass LeptosOptions. This will require a few small but key changes to apps uses Axum migrating from 0.3.x to 0.4.0. Click here to see a diff with the necessary changes.
• Switch from defaulting to nightly and opting into stable, to requiring an opt-in for nightly features. Click here to see a diff with the necessary changes.
  • If you're using stable, remove the stable feature (it's now the default.)
  • If you're using nightly, add the nightly feature to leptos, leptos_router, and leptos_meta
• leptos no longer defaults to csr, but is opt-in.
  • If you're using CSR, add the csr feature to leptos (same as leptos_router and leptos_meta
  • If you're using SSR/hydration, you can remove most default-features = false on Leptos dependencies, as that mainly served to disable the default csr feature, which is no longer enabled by default.
• ServerFnError no longer implements std::error::Error (see below). ServerFnErrorErr does, if that's needed.
• The children of a <Suspense/> or <Transition/> are now rendered once, then subsequently cloned. If you are reading resources reactively (move || data.read(cx)) they should continue to update reactively. If you are reading resources non-reactively (<div>{resource.read(cx)}</div>) this would have worked previously, and now will not be reactive.

Features

Automatic Server Function Registration

Server functions no longer need to be registered (except on exotic platforms like server-side WASM). Instead, they are registered automatically, making it even easier to define and use them.

Axum Extractor Support

You can now use Axum extractors directly in server functions.

#[server(QueryExtract, "/api")]
pub async fn query_extract(cx: Scope) -> Result<String, ServerFnError> {
    use axum::{extract::Query, http::Method};
    use leptos_axum::extract;

    extract(cx, |method: Method, res: Query<MyQuery>| async move {
            format!("{method:?} and {}", res.q)
        },
    )
    .await
    .map_err(|_| ServerFnError::ServerError("Error with server extractor".into()))
}

Improved Error Handling

Leptos now provides a leptos::error::Result type that behaves much like anyhow::Result (i.e., other errors can be converted into it using ?) but can be rendered directly in the view and caught by <ErrorBoundary/>. ServerFnError can also handle conversion from any error, making errors in server functions easier to handle.

use leptos::error::Result;

async fn fetch_cats(count: CatCount) -> Result<Vec<String>> {
    if count > 0 {
        // make the request
        let res = reqwasm::http::Request::get(&format!(
            "https://api.thecatapi.com/v1/images/search?limit={count}",
        ))
        .send()
        .await?
        // convert it to JSON
        .json::<Vec<Cat>>()
        .await?
        // extract the URL field for each cat
        .into_iter()
        .take(count)
        .map(|cat| cat.url)
        .collect::<Vec<_>>();
        Ok(res)
    } else {
        Err(CatError::NonZeroCats.into())
    }
}

#[server(AddTodo, "/api")]
pub async fn add_todo(title: String) -> Result<(), ServerFnError> {
    let mut conn = db().await?;

    Ok(
        sqlx::query("INSERT INTO todos (title, completed) VALUES ($1, false)")
            .bind(title)
            .execute(&mut conn)
            .await
            .map(|_| ())?,
    )
}

Async Routing

While routing, optionally wait for the next route to load before navigating, approximating the behavior of a multi-page app more closely, by using the set_is_pending prop on <Router/> and the <RoutingProgress/> component. (See #1055.)

#[component]
pub fn App(cx: Scope) -> impl IntoView {
    let (is_routing, set_is_routing) = create_signal(cx, false);

    view! { cx,
        <Router set_is_routing> // will wait for async data on next page to load before navigating

Screen.Recording.2023-05-20.at.9.34.42.PM.mov

<Await/>

The new <Await/> component improves the ergonomics of loading async blocks.

async fn fetch_monkeys(monkey: i32) -> i32 {
  // do some expensive work
  3
}

view! { cx,
	<Await
        future=|cx| fetch_monkeys(3)
        bind:data // see below for bind:
    >
        <p>{*data} " little monkeys, jumping on the bed."</p>
    </Await>
}

bind: syntax on components and slots

The children prop currently only supports one argument, the Scope. It's sometimes useful to be able to pass additional arguments to be used in children, but they need to be named. bind: allows you to define a children prop that takes additional arguments and name them. For example, the <Await/> component (see above) is defined like this

pub fn Await<T, Fut, FF, VF, V>(
	/* ... other props */
    children: VF,
) -> impl IntoView
where
    /* ... other generics */
    VF: Fn(Scope, &T) -> V + 'static,

The identifier for this second &T argument is then given with bind:{ident} (again, see above.)

Other Features

• Rewritten and less-buggy <For/> implementation.
• Specify exact server function paths with a fourth argument, rather than the hashed path used by default to avoid name collisions

#[server(MyServerFnType, "/api-prefix", "Url", "hello")] // will be at `/api-prefix/hello`

• Significant reductions in overhead of hydration keys, and therefore in SSR performance.
• Improvements to recoverability, error handling, and syntax highlighting in the view macro.

`v0.3.1`

Earlier this week, the ouroboros crate, a dependency of leptos_reactive, identified a fundamental soundness issue. This was fixed immediately in Leptos on the main branch by switching to self_cell instead. However, there have been a number of breaking changes on main since 0.3.0 in preparation for 0.4.0, so main could not be released as 0.3.1. There are a number of other changes that need to be made before 0.4.0, so it did not make sense to immediately release a new major version.

This patch release just rewinds to 0.3.0 and replaces ouroboros, without including any additional features or changes since then. If you have already been using main, you should continue using main. If you have been using 0.3.0, you should update to 0.3.1.

See additional discussion here.

`v0.3.0`

v0.3.0 is another incremental-ish release with a bunch of new features, many on the server end but including a bunch of general-purpose improvements. It includes several things that are breaking changes in the semantic-versioning sense, but you may find that not much breaks in your actual app. (For example, no code in any of the the three starter templates needed to change.)

New Features and Small Fixes

General

• No longer necessary to import __Props types for components; you can just use app::MyComponent; instead of app::{MyComponent, MyComponentProps};
• #[slot] syntax to define typed component children.
• Typed events in window_event_listener
• Optional event listeners with HtmlElement::optional_event
• Adds style: syntax in the view macro to set individual styles, much like class: sets individual classes
• Simplify work with resources by adding a Resource::update method to reactively update current value.
• expect_context::<T>(cx) shorthand for use_context::<T>(cx).unwrap()

Server

• Support for server functions that use GET requests (with either URL or CBOR encoding), for easier caching.
• extract helper to directly use Actix extractors in a server function.
• Allow more complex data like structs and Vec<_> as server function arguments (anything that can be de/serialized by serde_qs)
• Support for rendering a <Route/> in response to additional HTTP methods/verbs, e.g., the classic PHP/multi-page-app style in which a POST request can be sent to a page and it will render a response. (See methods prop.)
• Support for SsrMode::PartiallyBlocked which works like out-of-order streaming but replaces the HTML for any “blocked” fragments on the server. Improves UX when JS is disabled.

Developer Experience and Ergonomics

• Top-to-bottom integration with the tracing crate
• Adding some "real-time docs" via several runtime warnings and compile-time errors to prevent common bugs (for example, using leptos_meta with no features enabled or accidentally ending the view a component returns with a semicolon, meaning it renders nothing)

Performance

• Improve performance of Axum integration by spawning requests into a local threadpool.
• Improve performance of router on the server side by caching branch generation.
• Performance improvements in the reactive system and renderer, and closing a memory leak in <Suspense/>/<Transition/>.

And as always...

• Lots of bug fixes! Full changelog below.

Breaking Changes

• &'a str can no longer be directly rendered as a view: add .to_string() to effected variables. (Previously, all &str were converted to String by the renderer; using Cow<'static, str> now allows &'static str to be rendered without the additional allocation, at the cost of requiring the conversion of &str to String to be more explicit.)
• window_event_listener now takes a typed event (like ev::keypress). Use window_event_listener_untyped for the old behavior.
• When deriving Params to use typed router search/params, the FromStr error for any type needs to be Send + Sync so they are ErrorBoundary compatible
• Generics in create_slice have changed to allow different input types for getter/setter; only relevant if (for some reason?) you were specifying them manually.
• Exact interfaces for a few public-but-rarely-needed functions in the server integrations have changed.

`v0.2.5`

v0.2.5

This update includes many bug fixes and documentation improvements, along with a few new features:

• A <ProtectedRoute/> component that allows you to create route guards to either render or redirect away from a route depending on some condition.
• The ability to add arbitrary attributes to the <Html/> and <Body/> components in leptos_meta.
• Additional head data injected using leptos_meta is now injected at the beginning of the <head> rather than the end, which allows you to inject an import map if necessary for JavaScript module imports.

I'm beginning to merge a few server-rendering changes that should be invisible to most users but will technically be breaking API changes, and will be building toward v0.3.0 which will probably include reconfiguring the Cargo setup for nightly/stable support (see #591), so this is may be the last 0.2.x release.

Full Changelog: v0.2.4...v0.2.5

`v0.2.4`

v0.2.3 fixed support for stable Rust, which I temporarily broke in v0.2.2.

The main change in v0.2.4 is a rewritten reactive system. This didn't involve any breaking API changes, except to the extent that fixing bugs and glitchy behavior breaks apps that depend on the glitches. It pretty significantly improves the performance of the reactive system on deep graphs (i.e., when you have a chain of dependencies like memos leading from a signal to an effect), as well as fixing reactive "glitching" behaviors in ways that make effects run more efficiently. You can read more about the details here.

Other changes:

• improved error handling in <ActionForm/>
• Support for using signals directly in the view in stable Rust
• cancelable versions of set_timeout, request_idle_callback, and request_animation_frame (all ending with with_handle)
• a debounce helper that makes it easy to debounce event listeners
• allow manual disposal of signals before the current reactive cope is disposed with the SignalDispose trait (and .dispose()) function, to avoid leaking memory if you create a list of signals at the root scope
• allow batching multiple updates with Scope::batch() before running effects
• many small bugfixes

Full Changelog: v0.2.0...v0.2.2

`v0.2.0`

v0.2.0

v0.2.0 is an incremental change over 0.1.x. There are a few small things that have been breaking changes over the last two months, one big new feature, and a lot of small improvements and changes.

Async Rendering and In-Order Streaming

The biggest new feature of 0.2.0 that requires explanation is support for async rendering and in-order streaming, which you can activate via the new ssr prop on a <Route/>. (See the ssr_modes and ssr_modes_axum examples.)

With this new feature, Leptos now supports four different ways to render HTML that contains async data loaded under <Suspense/>. You can opt in to one or the other on a per-route basis.

1. Synchronous: Serve an HTML shell that includes fallback for any Suspense. Load data on the client, replacing fallback once they're loaded.
   • Pros: App shell appears very quickly: great TTFB (time to first byte).
   • Cons: Resources load relatively slowly; you need to wait for JS + WASM to load before even making a request.
2. Out-of-order streaming: Serve an HTML shell that includes fallback for any Suspense. Load data on the server, streaming it down to the client as it resolves, and streaming down HTML for Suspense nodes.
   • Pros: Combines the best of synchronous and async, with a very fast shell and resources that begin loading on the server.
   • Cons: Requires JS for suspended fragments to appear in correct order. Weaker meta tag support when it depends on data that's under suspense (has already streamed down <head>)
3. In-order streaming: Walk through the tree, returning HTML synchronously as in synchronous rendering and out-of-order streaming until you hit a Suspense. At that point, wait for all its data to load, then render it, then the rest of the tree.
   • Pros: Does not require JS for HTML to appear in correct order.
   • Cons: Loads the shell more slowly than out-of-order streaming or synchronous rendering because it needs to pause at every Suspense. Cannot begin hydration until the entire page has loaded, so earlier pieces
     of the page will not be interactive until the suspended chunks have loaded.
4. async: Load all resources on the server. Wait until all data are loaded, and render HTML in one sweep.
   • Pros: Better handling for meta tags (because you know async data even before you render the <head>). Faster complete load than synchronous because async resources begin loading on server.
   • Cons: Slower load time/TTFB: you need to wait for all async resources to load before displaying anything on the client.

The mode defaults to out-of-order streaming. For a path that includes multiple nested routes, the most
restrictive mode will be used: i.e., if even a single nested route asks for async rendering, the whole initial
request will be rendered async. (async is the most restrictive requirement, followed by in-order, out-of-order, and synchronous.)

Because you have the ability to opt into these different modes on a per-route basis, you can choose the rendering strategy that is best for you—not only for your app in general, but for any given page.

Other Features and Improvements

• New <Html/> and <Body/> components in leptos_meta that let you change things like <html> lang and dir, and add a class to the <body>
• Restoring on: event listeners on <Component/> nodes, e.g., <MyFancyButton on:click=.../> without needing to create an on_click prop
• Adding a <Redirect/> component in the router that works during client-side navigation or server-side rendering
• Children, AttributeValue, and other type aliases to make it easier to accept a variety of types in your components
• Experimentation with new docs using CodeSandboxes and an expanding set of tutorials
• So, so, so, so many bugfixes, typos, docs improvements, and small changes by many, many, many members of the community. Thanks to you all!

Breaking Changes Since 0.1.3

• Resource::read() and Resource::with() now take a Scope as their first argument, i.e., resource.read() is now resource.read(cx). This is necessary for correct <Suspense/> behavior.
• The Errors type has been modified to hide its internals and expose IntoIter directly. In 99% of cases this just means replacing references like errors.get().0.into_iter() with errors.get().into_iter()
• Most of the methods on various signal types have been moved into traits instead. This should not cause any actual changes to the way you use them, and if you are accustomed to use leptos::* you probably won't notice the difference; if you are manually importing types you will need to import the signal traits as well.
• The <For/> component view argument now takes a Scope as its first argument, i.e., a change from view=move |counter| { ... } to view=move |cx, counter| { ... }
• The <ErrorBoundary/> component fallback argument now takes a Fn(Scope, RwSignal<Errors>) -> impl IntoView instead of Fn(Scope, Option<RwSignal<Errors>>) -> impl IntoView
• NodeRef now takes NodeRef<T> instead of NodeRef<HtmlElement<T>>. We're also deprecating NodeRef::new(cx) in favor of create_node_ref(cx) to follow the same pattern as everything else in the framework.
• We've finally achieved full consistency between cargo-leptos and the server integrations whether you're using cargo-leptos or not. The site_address field is now named site_addr; the compiler should actually prompt you correctly for this one.
• The current Leptos global namespace is polluted with a huge number of types and reexports, making it harder to find things in docs and adding compile-time overhead. If you're used to use leptos::* you may need to manually import a few additional types. We're also no longer reexporting wasm-bindgen, web-sys, and js-sys so you may need to add them as dependencies to your Cargo.toml
• APIs to modify status code and headers in HTTP responses are now synchronous, making them easier to set in components

This release is a preview, and also serves to generate new docs on docs.rs, as the current ones are getting slightly out of sync with our main branch here.

I do not expect significant difficulties in migrating from 0.1.3 to 0.2.0. There are a few API tweaks here that necessitate a version bump but it's an order of magnitude smaller than the change from 0.0.x to 0.1.0 and will not touch most parts of your application.
