Changelog

Unreleased

Fixed

  • hx.hooks/useMemo: deps are optional and can be CLJS collection.

[0.5.3] - July 31, 2019

Changed

  • useIRef now uses specify instead of a wrapper, and refers to the current property on itself. This allows you to pass in the ref object directly to DOM ref prop.

[0.5.2] - May 16, 2019

Added

  • Alpha hooks useSmartEffect, useSmartLayoutEffect, useSmartMemo that auto-detect dependencies based on the body.

Fixed

  • useState and useIRef now properly memoize their dispatch functions to prevent unnecessary renders.
  • useReducer can now be passed IFn's like multimethods

[0.5.1] - May 05, 2019

Fixed

  • Function-as-children were not passing props correctly

[0.5.0]

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
