Changelog

✨ 0.9 (TBD)

  • ⚡️ Features

    • The derive props macro now supports Properties with lifetimes [@jstarry, #580]
    • New ResizeService for registering for window size updates [@hgzimmerman, #577]

  • 🛠 Fixes

  • 🚨 Breaking changes

✨ 0.8 (2019-08-10)

Props! Props! Props!

This release introduces a more developer friendly way to handle your Component props. Use the new #[derive(Properties)] macro to beef up your props! Property values can now be annotated as #[props(required)] which will enforce that props are present at compile time. This means that your props struct no longer needs to implement Default, so time to clean up all of those prop values you wrapped in Option to have a default value.

  • ⚡️ Features

    • html! - Self-closing html tags can now be used: <div class="marker" /> [@totorigolo, #523]
    • html! - SVG name-spaced tags are now supported! [@jstarry, #550]
    • Properties can now be required at compile time [@jstarry, #553]
    • App components can now be mounted with properties [@jstarry, #567]
    • Apps can now be mounted as the <body> tag [@jstarry, @kellytk, #540]
    • Content editable elements can now trigger oninput events [@tiziano88, #549]

  • 🛠 Fixes

    • html! - Class name order is now preserved which unlocks the use of Semantic UI [@charvp, #424]
    • html! - Dashed tag names and properties are supported [@jstarry, #512, #550]
    • html! - All rust keywords can be used as tag attributes [@jstarry, #550]
    • html! - Support Callback closure with explicit return type [@totorigolo, #564]
    • html! - Fixed edge case where > token would break parser [@totorigolo, #565]
    • Performance improvement to the diff engine [@totorigolo, #539]
    • Properties no longer need to implement the PartialEq, Clone, or Default traits [@jstarry, #553]
    • Component will not panic if the change method is unimplemented [@jstarry, #554]

  • 🚨 Breaking changes

    • The Component::Properties associated type must implement the new Properties trait [@jstarry, #553]

      The new Properties trait is what powers the ability to check required props are present at compile time. Use the derive props macro to implement automatically.

      use yew::Properties;

#[derive(Properties)]
pub struct Props {
  #[props(required)]
  pub value: MyStruct,
}

    • Callback props no longer transform into Option types [@jstarry, #553]

      html! { <Button on_click=Msg::Click /> }

      before:

      #[derive(PartialEq, Clone, Default)]
pub struct Props {
    on_click: Option<Callback<()>>,
}

      after: note the #[props(required)] attribute

      #[derive(PartialEq, Properties)]
pub struct Props {
    #[props(required)]
    on_click: Callback<()>,
}

✨ 0.7 (2019-07-19)

Commas? We don't need no stinkin' commas!

This release brings a new and improved html! macro for writing JSX-like syntax. Commas and colons are no longer necessary now that the macro is written as a procedural macro.

  • ⚡️ Features

    • html!{} is now valid syntax and can be used to render nothing [@jstarry, #500]
    • Apps can now be built without cargo-web using wasm-bindgen [@jstarry, #497]
    • Callback now implements Debug [@DenisKolodin, #485]
    • New utility method for getting the host of the current page [@DenisKolodin, #509]

  • 🛠 Fixes

    • html! - Commas are no longer necessary for splitting up attributes [@jstarry, #500]
    • html! - Colons are no longer necessary for denoting a Component tag [@jstarry, #500]
    • Textarea value can be now be set: <textarea value="content"> [@DenisKolodin, #476]
    • changed StorageService::restore to take an immutable receiver [@dermetfan, #480]
    • Fixed a component rendering bug [@jstarry, #502]

✨ 0.6 (2019-02-20)

  • ⚡️ Features

    • Added start_app convenience method for initializing the app and mounting it to the body [@DenisKolodin, #462]
    • Added handling of files of input element. There is now a ChangeData::Files variant for the onchange handler [@DenisKolodin, #464]
    • Added ReaderService to read data from File instances. [@DenisKolodin, #464, #468]

  • 🛠 Fixes

    • It was impossible to set value attribute for any tag instead of option, because it used inner value of VTag to keep the value for input element. Now value attribute works for options, progress tags, etc.

  • 🔮 Examples

✨ 0.5 (2019-02-01)

🎶 Secret Agent Man 🎶

This release introduces the concept of an Agent. Agents are separate activities which you could run in the same thread or in a separate thread. There are three types of agents Context, Job, Public described below. To connect to an agent use the Worker::bridge method and pass a link of component's environment to it.

  • ⚡️ Features

    • Introduced the concept of an Agent which can run processes in other contexts:
      • Context agent spawns once per thread
      • Job agent spawns for every bridge
      • Public agent spawns an agent in a separate thread (it uses Web Workers API under the hood).
    • Allow setting the whole properties struct of a component with <Component: with props />
    • ComponentLink now has a send_self method which allows components to update themselves [@DenisKolodin, #365]
    • All services are re-exported within the yew::services module.
    • html! macro supports multiple classes in a single string: <a class="button is-primary",>.
    • Added FetchOptions to allow setting Credentials of fetch request.
    • FetchService aborts requests using AbortController.
    • Added SubmitEvent with onsubmit rule.

  • 🛠 Fixes

    • Bug with emscripten target RuntimeError: index out of bounds fixed with a new scheduler [@DenisKolodin, #272]

  • 🚨 Breaking changes

    • send_back method requires a mutable reference to self. This was added to prevent creating callbacks in view implementations. [@DenisKolodin, #367]
    • Context requirement removed. It's no longer necessary to use Component<CTX> type parameter. Instead, a link to the environment is provided with the Component::create call. [@DenisKolodin, #272]
