Changelog

[Unreleased]

Fixed

• <-value hook mutated ref in render, making it not safe for use in Concurrent React
• Converting prop className to class was only done when hiccup parsing; now also happens in defnc so it works with cloneElement.
• Improved hiccup interpretation by 10x

Changed

• Deprecated Hooks names prepended with <-; adopted useXyzAbc convention
• Changed API for extending components; now you can call (extend-tag :new-tag ReactComponentToUse)

Added

• A new hx.hooks.alpha namespace with experimental Hooks
• Alpha-level "reloadable" hook useReloadable and useStateOnce that persist their state across hot reloads.

[0.4.0] - Mar 26, 2019

Changed

• <-state now returns a [value set-value] tuple instead of an atom.
• props passed into hiccup are only converted camel->kebab and back if the element is a keyword.
• hx.hiccup is now cross-platform (CLJ + CLJS) and has been decoupled from React

Added

• <-value hook that caches the Clojure value passed into it, and only returns a (referentially) different value if it is not= the previous one. Useful for optimizing renders with things that might return the same data structurally, but with a different reference.
• <-state's update function can take arguments like swap!, e.g. (set-value assoc :foo "bar")
• <-state can take a third argument: a function that returns true if the new value and previous value are equal. If true, it will not apply the change.
• Lots of tests
• defnc and defcomponent components now have prettier display names (for e.g. React devtools)
• defnc now can be passed a :wrap option with a collection of higher-order components to wrap the component in

Fixed

• :class prop having value nil when :class-name not present
• Special chars (e.g. ?) in props being dropped
• <-effect where a function is not returned by f caused an error
• <-ref was just broken

[0.3.3] - Mar 08, 2019

Added

• :provider component and hx.react/create-context function

Fixed

• Race condition in <-deref hook
• Props with numbers, two-letter camel-case were dropped or truncated

[0.3.2] - Feb 25, 2019

Fixed

• <-state: swap! works on a <-state atom inside of <-effect
• className prop is available as either :class or :class-name when parsing props in defnc to provide parity with hiccup parser's conversion of :class prop to className
• namespaced keywords are now preserved in props maps

[0.3.1] - Feb 20, 2019

Fixed

• <-ref: Pass initial value to react/useRef

[0.3.0] - Feb 10, 2019

Changed

• Moved hx.react.hooks to hx.hooks (breaking)
• <-deref: no longer takes a deps argument, but will automatically re-watch if atom argument changes (breaking)
• <-deref: Fix bug where two calls on the same atom didn't work as expected
• <-effect: Convert second argument deps from CLJS collection to array
• <-ref: Have deref return the current value in React ref (breaking)

Added

• Additional core hooks:
  • <-memo
  • <-callback
  • <-imperative-handle
  • <-layout-effect
  • <-debug-value
