Raw Blame History

Changelog

0.4.2

  • Allow multi-methods as component functions.

  • Tweak performance by avoiding clojure.core/memoize.

  • Bugfix: Allow on-change handler on controlled inputs to keep value unchanged.

0.4.1

  • Made Reagent compatible with ClojureScript 0.0-2173. reagent.core/atom now implements the necessary IAtom, ISwap and IReset protocols. Reagent should still be compatible with older ClojureScript versions, but you will get a lot of compilation warnings.

0.4.0

  • Breaking change: Component functions can get arbitrary arguments, and not just vectors and maps. This is a breaking change, but behaviour is unchanged if you pass a map as the first argument (as in all the examples in the old documentation).

  • React updated to 0.9.0.

  • You can now use any object that satisfies ifn? as a component function, and not just plain functions. That includes functions defined with deftype, defrecord, etc, as well as collections like maps.

  • reagent.core/set-state and reagent.core/replace-state are now implemented using a reagent.core/atom, and are consequently async.

  • Keys associated with items in a seq (e.g ”dynamic children” in React parlance) can now be specified with meta-data, as well as with a :key item in the first parameter as before. In other words, these two forms are now equivalent: ^{:key foo} [:li bar] and [:li {:key foo} bar].

  • Performance has been improved. For example, there is now practically no overhead for tracking derefs in components that dont use atoms. Allocations and memory use have also been reduced.

  • Intro and examples have been tweaked a little to take advantage of the new calling conventions.

0.3.0

  • Changes in application state are now rendered asynchronously, using requestAnimationFrame.

  • Reagent now does proper batching of updates corresponding to changed atoms, i.e parents are rendered before children, and children are only re-rendered once.

  • Add reagent.core/flush to render changes immediately.

  • Bugfix: Allow dynamic id with hiccup-style class names.

0.2.1

  • Bugfix: allow data-* and aria-* attributes to be passed through unchanged.

0.2.0

  • Rename Cloact to Reagent, due to popular disgust with the old name...
