Release post: https://sycamore-rs.netlify.app/news/announcing-v0.7.0

• ⚡️ Features

  • Implement TryFromSegments for T: Route. This allows the creation of nested routers. See the docs for more information about usage.
  • Make parenthesis optional in cloned! macro. The following syntax is now accepted, in addition to the old syntax:

    // Before
    cloned!((my, variables, to, clone) => move || { ... })
    // After
    cloned!(my, variables, to, clone => move || { ... })

  • Builder API. Check out the hello-builder example for more usage details.
  • Make wasm-bindgen-interning a feature. This feature is enabled by default but can be opted-out which would disable wasm-bindgen/enable-interning. Opting-out can lead to a slight decrease in binary size at the cost of performance.
  • Introduce render_get_scope function. This allows accessing (and disposing of) the ReactiveScope created by the render function.
  • Hydration support. To enable hydration, replace calls to render and render_to with hydrate and hydrate_to.
  • Add #[track_caller] to use_context. This makes it much easier to debug the "context not found for type" error.
  • Better debugging utilities for inspecting the ReactiveScope hierarchy.

• 🛠 Fixes

  • Prevent data binding from panicking when not in browser.
  • Extend ReactiveScope into scopes that are siblings.
  • Fix Lerp implementation for integers.
  • Fix context API not working through Indexed and Keyed.
  • Update TodoMVC example to use context API.
  • Remove autocomplete from the list of boolean attributes for codegen.
  • Fix parenthesizing of expressions in view! macro interpolation syntax.
  • Fix context API when effects are re-executed.
  • Allow constant generics to be used with #[component] macro.

• 📃 Documentation

  • Add a note in the docs about Trunk CSS support.
  • Fix typo in README.md.

• Internal

  • Collect code coverage in CI.
  • Deprecate create_root in favor of create_scope.
  • Fix website npm build script.

• 🚨 BREAKING CHANGES

  • Refactor GenericNode and introduce Html trait. Add IS_BROWSER constant to Html.. For projects that target HTML, it is recommended to use the Html trait instead of GenericNode. This will ensure that it cannot be used on rendering backends that are not for HTML. To check if code is executing on the browser, access the Html::IS_BROWSER constant on the generic rendering backend. This also slightly changes the GenericNode interface which is why it is a breaking change but would most likely not influence you.
  • Make GenericNode generic over the event type. The event type is now an associated type to allow rendering backends to use another type from web_sys::Event.
  • Rename Template to View and template! to view!. For most cases, a simple search-and-replace will suffice, replacing all instances of Template to View and all instances of template! to view!.
  • Rename StateHandle to ReadSignal. The old name was somewhat confusing and did not reflect that StateHandle was just a read-only signal.
