`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

allowing multiple class names in class = syntax in view! macro
provide a new LeptosRequest<_> type that allows Leptos Axum apps access to the request via use_context, which allows you to use Axum extractors without a special handler

v0.2.0

3d50ca3

`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.

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.
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>)
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.
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

Included below are the notes for 0.2.0-alpha, so you can see changes since 0.1.3 as well.

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.

`v0.1.3`

The big changes here are the <ErrorBoundary/> and <Show/> components. Many thanks to @benwis for leading the work on these.

You should also see a very significant improvement in SSR performance, as well as small reductions in Wasm binary sizes, and some overall bugfixes and improvements.

Oh, and... 🎵🎶 We don't talk about 0.1.2. 🎶🎵

v0.1.0

08ec473

v0.1.0

Finally, here's the release for version 0.1.0. Thanks to everyone who's been working with the alpha, beta, and bleeding-edge versions over the last few weeks to help get everything ready.

Most of the release notes below are copied from the 0.1.0-alpha release, but include a few updates. All these changes are relative to 0.0.22.

Features

More flexible rendering

You can now easily mix and match different types of node in a Fragment, which previously needed to be a Vec of all the same types (like a Vec<Fragment>).

view! { cx,
  <>
    "This is some text."
    <p>"Here's an element."</p>
    <ComponentA/>
  </>
}

In fact, the <> fragment itself is optional.

view! { cx,
  "This is some text."
  <p>"Here's an element."</p>
  <ComponentA/>
}

Typed HTML elements

HTML elements generated by the view! macro are now typed, and implement Deref to give a correctly-typed web_sys element.

// returns `HtmlElement<Input>`
// derefs to a `web_sys::HtmlInputElement`
view! { cx, <input type="text"/> }

`store_value`

You can now store non-reactive values in the reactive system to take advantage of the same Copy + 'static reference system without the overhead or abstraction leak of storing something in a signal. This is useful for objects you need to reference in multiple places throughout your application without cloning.

// this structure is neither `Copy` nor `Clone`
pub struct MyUncloneableData {
  pub value: String
}

// ✅ you can move the `StoredValue` into closures and access it with .with()
let data = store_value(cx, MyUncloneableData { value: "a".into() });
let callback_a = move || data.with(|data| data.value == "a");
let callback_b = move || data.with(|data| data.value == "b");

`Signal<T>` and `SignalSetter<T>` abstractions

These wrappers allow you to define APIs that can take any kind of signal. For example, Signal<T> can be a ReadSignal, RwSignal, Memo, or derived signal. This is especially useful when defining components interfaces. (There's even a MaybeSignal for types that may just be T or may be a Signal<T>.)

let (count, set_count) = create_signal(cx, 2);
let double_count = Signal::derive(cx, move || count() * 2);
let memoized_double_count = create_memo(cx, move |_| count() * 2);

// this function takes any kind of wrapped signal
fn above_3(arg: &Signal<i32>) -> bool {
  // ✅ calling the signal clones and returns the value
  //    it is a shorthand for arg.get()
  arg() > 3
}

assert_eq!(above_3(&count.into()), false);
assert_eq!(above_3(&double_count), true);
assert_eq!(above_3(&memoized_double_count.into()), true);

Massively improved Rust Analyzer support

DX with this new system is much better. You'll see hugely improved language-server integration for the view! macro, including features like doc comments for HTML elements, autocompletion for component properties, clicking to go to the definition of a component, type hints for component arguments, etc.

Inline documentation in the `#[component]` macro

You can now document components and their properties directly in the #[component] macro like this:

/// A simple counter component.
/// 
/// You can use doc comments like this to document your component.
#[component]
pub fn SimpleCounter(
  cx: Scope,
  /// The starting value for the counter
  #[prop(optional)]
  initial_value: i32,
  /// The change that should be applied each time the button is clicked.
  step: i32
) -> impl IntoView {
  // ...
}

The macro will automatically generate docs for the components and for each of its props.

`#[prop]` attributes for component props

You can use the #[prop] attribute macro to mark component props in several ways:

#[prop(into)]: This will call .into() on any value passed into the component prop. (For example,
you could apply #[prop(into)] to a prop that takes Signal, which would
allow users to pass a ReadSignal or RwSignal
and automatically convert it.)
#[prop(optional)]: If the user does not specify this property when they use the component,
it will be set to its default value. If the property type is Option<T>, values should be passed
as name=T and will be received as Some(T).
#[prop(optional_no_strip)]: The same as optional, but requires values to be passed as None or
Some(T) explicitly. This means that the optional property can be omitted (and be None), or explicitly
specified as either None or Some(T).
#[prop(default = X)]: The property is optional, and will be set to the default value provided if it is not passed.

`tracing` support

We've added support for debugging using the tracing crate, integrated into both the renderer and the reactive system. This means that when an effect or an event listener fires, you can use trace!(...) to get an insight into the flow of your program. See leptos_dom/examples/test-bench for an example setup; a separate crate to make this tracing setup easier will be forthcoming.

`cargo-leptos` integration improvements

cargo-leptos 0.1.2 and the Actix/Axum integrations in 0.1.0 now work together seamlessly, allowing you to create full-stack applications with as little boilerplate as possible.

And much more!

Comments that mark component boundaries for easier debugging, when in debug mode
Removing the need to wrap things that <Router/> in a <div> for no obvious reason
builder API that allows you to crate a UI without using the view macro
and all sorts of things I'm forgetting!

Breaking Changes

Here are a few things to watch out for as you migrate:

If you're using cargo-leptos already and run into any issues (for example, with the path of a JS or Wasm file), be sure to check out the latest examples and the starter. The extra structures here have changed a bit over time as we've tried to figure out the best patterns. Cloning the starter and adding your existing application code should work fine.
All component functions should now return -> impl IntoView
The <For/> component now takes a view property, instead of you passing the view function as the child of the component
Likewise, the <Route/> component takes a view property instead of element for consistency
children properties are now typed Box<dyn Fn(Scope) -> Fragment>
The view! macro returns distinct structures, which are all different types. In other words, this code no longer compiles

// this won't work
if some_condition {
  view! { cx, <p>"P if true"</p> }
} else {
  view! { cx, <span>"SPAN if false"</span> }
}

because the first branch now returns HtmlElement<P> while the second returns HtmlElement<Span>.

In this case, simply add .into_any() to each to return HtmlElement<AnyElement> from both. In general, you can always call .into_view(cx) to return a wrapping View type instead.

// this works
if some_condition {
  view! { cx, <p>"P if true"</p> }.into_any()
} else if something_else {
  view! { cx, <span>"SPAN if false"</span> }.into_any()
}

v0.1.0-beta

a2943c4

v0.1.0-beta Pre-release

Pre-release

`v0.1.0-beta`

This release mostly (see crates.io) consists mainly of polishing the many changes described in the 0.1.0-alpha release notes.

Other significant improvements include:

New store_value() and StoredValue APIs that allow you to use the reactive system to store Copy and 'static handles to non-reactive values, just as you can with reactive signals.
Finally, complete integration with the cargo-leptos build tool, including transitioning most of the examples over to use cargo-leptos (except for the client-only examples, which use Trunk) (kudos and many thanks to @benwis and @akesson)
Restoring stable support for the new version (thanks to @jquesada2016)

... in addition to many small bug-fixes.

We're making very good progress toward a final 0.1.0 release. The only outstanding changes at this point involve improving and updating documentation, slightly loosening a couple APIs to make them easier to use (for example, allowing the path property on <Route/> to take T: impl std::fmt::Display rather than &'static str), and a few performance improvements (like optimized SSR) that will have absolutely no effect on the API exposed to users, but continue to ensure high performance and a good experience.

v0.1.0-alpha

v0.1.0-alpha Pre-release

Pre-release

A preview of `v0.1.0`

🎄 Merry Christmas!

I thought I'd offer this alpha release of the upcoming 0.1.0 so you can get a taste for some of what we've been working on. Shout out to @jquesada2016 for driving the work on the rewritten renderer that got us here, as well as huge improvements to the #[component] macro and many other details of the framework.

You can track the current state of this work in PR #119. You can download the alpha from crates.io.

There are a few known issues still (see below) but this release should be more or less usable, and the APIs are pretty much final. You can expect something closer to a final release in the next few weeks, but here's what to look forward to in the meantime.

Features

More flexible rendering

You can now easily mix and match different types of node in a Fragment, which previously needed to be a Vec of all the same types (like a Vec<Fragment>).

view! { cx,
  <>
    "This is some text."
    <p>"Here's an element."</p>
    <ComponentA/>
  </>
}

Typed HTML elements

HTML elements generated by the view! macro are now typed, and implement Deref to give a correctly-typed web_sys element.

// returns `HtmlElement<Input>`
// derefs to a `web_sys::HtmlInputElement`
view! { cx, <input type="text"/> }

Massively improved Rust Analyzer support

Inline documentation in the `#[component]` macro

You can now document components and their properties directly in the #[component] macro like this:

/// A simple counter component.
/// 
/// You can use doc comments like this to document your component.
#[component]
pub fn SimpleCounter(
  cx: Scope,
  /// The starting value for the counter
  #[prop(optional)]
  initial_value: i32,
  /// The change that should be applied each time the button is clicked.
  step: i32
) -> impl IntoView {
  // ...
}

The macro will automatically generate docs for the components and for each of its props.

`#[prop]` attributes for component props

You can use the #[prop] attribute macro to mark component props in several ways:

#[prop(optional)]: this property is not required, and will default to Default::default() if you don't provide it in the view
#[prop(into)]: .into() will be called to convert the arguments provided in the view you can specify, to save you adding .into() in your views

And much more!

} else if something_else {
  view! { cx, <span>"SPAN if false"</span> }.into_any()
}

Outstanding Issues (in progress)

The <Transition/> component doesn't quite work properly yet.
SSR + hydration is slightly broken if you use create_resource and read it without using <Suspense/>
There may be some bugs in SSR + hydration in release mode, as this has not been fully tested yet
SSR is temporarily slower than the current version, as I haven't implemented the fast-path in the view! macro yet
Merge over stable support for leptos_router and leptos_meta
