leptos-use/CHANGELOG.md

# Changelog

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased] - 

### New Functions 🚀

- `use_mouse_in_element`
- `use_device_pixel_ratio` (thanks to @mondeja)
- `use_element_bounding`

### Fixes 🍕

- Fixed `use_geolocation` SSR compile issue
- Fixed `use_intl_number_format` maximum fraction digits option

### Changes 🔥

- The `UseMouseReturn` signals `x`, `y`, and `source_type` are now of type `Signal<f64>` instead of `ReadSignal<f64>`.
- You can now convert `leptos::html::HtmlElement<T>` into `Element(s)MaybeSignal`. This should make functions a lot easier to use in directives.
- There's now a chapter in the book especially for `Element(s)MaybeSignal`.
- Throttled or debounced callbacks (in watch_* or *_fn) no longer are called after the containing scope was cleaned up.
- The document returned from `use_document` now supports the methods `query_selector` and `query_selector_all`.

## [0.9.0] - 2023-12-06

### New Functions 🚀

- `use_display_media` (thanks to @seanaye)

### Breaking Changes 🛠

- (@feral-dot-io) The use `use_<type>_storage` functions have been rewritten to use `Codec`s instead of always
  requiring `serde`.
    - This also removes the feature `storage`
    - By default the `StringCodec` is used which relies on types implementing `FromString + ToString`
    - If you want to use `JsonCodec` you have to enable the feature `serde`
    - If you want to use `ProstCodec` (new!) you have to enable the feature `prost`.
- (@feral-dot-io) The Rust flag `--cfg=web_sys_unstable_apis` is not needed anymore since relevant `web_sys` APIs are
  now stable.
  This affects in particular
    - `use_element_size`
    - `use_resize_observer`

### Fixes 🍕

- `use_raf_fn` and `use_timestamp` no longer spam warnings because of `get`ting signals outside of reactive contexts.
- `use_infinite_scroll` no longer calls the callback twice for the same event
- `use_scroll` now uses `try_get_untracked` in the debounced callback to avoid panics if the context has been destroyed
  while the callback was waiting to be called.
- `use_idle` works properly now (no more idles too early).
- `use_web_notification`  doesn't panic on the server anymore.

## [0.8.2] - 2023-11-09

### Fixes 🍕

- Fixed SSR for
    - use_timestamp
    - use_raf_fn
    - use_idle

## [0.8.1] - 2023-10-28

### Fixes 🍕

- Using strings for `ElementMaybeSignal` and `ElementsMaybeSignal` is now SSR safe.
    - This fixes specifically `use_color_mode` to work on the server.

## [0.8.0] - 2023-10-24

### New Functions 🚀

- `use_web_notification` (thanks to @centershocks44)
- `use_infinite_scroll`
- `use_service_worker` (thanks to @lpotthast)

### Breaking Changes 🛠

- `use_scroll` returns `impl Fn(T) + Clone` instead of `Box<dyn Fn(T)>`.

### Other Changes 🔥

- `UseScrollReturn` is now documented

## [0.7.2] - 2023-10-21

### Fixes 🍕

- Some functions still used `window()` which could lead to panics in SSR. This is now fixed.
  Specifically for `use_draggable`.

## [0.7.1] - 2023-10-02

### Breaking Changes 🛠

- Leptos version is now 0.5
- No `cx: Scope` params are supported/needed anymore because of the changes in Leptos.
  Please check the release notes of Leptos 0.5 for how to upgrade.
- `watch` is now deprecated in favor of `leptos::watch` and will be removed in a future release.
  `watch_with_options` will continue to exist.
- `use_event_listener_with_options` now takes a `UseEventListenerOptions` instead of
  a `web_sys::AddEventListenerOptions`.
- `use_mutation_observer_with_options` now takes a `UseMutationObserverOptions` instead of
  a `web_sys::MutationObserverInit`.
- `use_websocket`:
    - takes now a `&str` instead of a `String` as its `url` parameter.
    - same for the returned `send` method.
    - The `ready_state` return type is now renamed to `ConnectionReadyState` instead of `UseWebSocketReadyState`.
    - The returned signals  `ready_state`, `message`, `message_bytes` have now the type
      `Signal<...>` instead of `ReadSignal<...>` to make them more consistent with other functions.
    - The options `reconnect_limit` and `reconnect_interval` now take a `u64` instead of `Option<u64>` to improve DX.
    - The option `manual` has been renamed to `immediate` to make it more consistent with other functions.
      To port please note that `immediate` is the inverse of `manual` (`immediate` = `!manual`).
    - Added documentation how pass it ergonomically as context.
- `use_color_mode`:
    - The optional `on_changed` handler parameters have changed slightly. Please refer to the docs for more details.
- Throttled or debounced functions cannot be `FnOnce` anymore.
- All traits `ClonableFn...` have been removed.

### Other Changes 🔥

- `use_websocket` can use relative urls now
- Callbacks in options don't require to be cloneable anymore
- Callback in `use_raf_fn` doesn't require to be cloneable anymore
