v0.2.0-alpha

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.

Breaking Changes

  • 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

Other 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!
