Changelog

Upcoming

  • Reagent no longer bundles React. Instead it uses cljsjs/react as a dependency. This means that you should no longer specify React in :preamble in your project.clj.

  • adapt-react-class makes it easier to use "native" React components with Reagent.

  • cursor is re-written, to be more efficient and flexible.

  • render now forces a deep update of all components, to make it more convenient to use with e.g. figwheel.

  • Renamed as-component to as-element, to match React's new terminology better (old name still works, though, for backward compatiblity).

  • Stop wrapping native components. This reduces the number of components created a lot, and can speed some things up substantially (especially render-to-string, that is not bound by browser performance). This is made possible by a new way of keeping track of which order to re-render dirty components.

  • Added create-element to make it easier to embed native React components in Reagent ones.

  • Arguments to components are now compared using simple =, instead of the old, rather complicated heuristics. NOTE: This means all arguments to a component function must be comparable with = (which means that they cannot be for example infinite seqs).

  • React updated to 0.12. Reagent now creates all React components using React.createElement.

  • render-component is now render, and render-component-to-string is render-to-string, in order to match React 0.12 (but the old names still work).

  • Add render-to-static-markup. This works exactly like render-to-string, except that it doesn't produce data-react-id etc.

  • create-class now takes a Reagent-style render function (i.e with the same arguments you pass to the component), called :reagent-render.

0.4.3

  • React updated to 0.11.2

  • Add reagent.core/cursor

  • Add javascript interop macros .' and .!

  • Add force-update-all to make LightTable integration easier

  • Some performance optimizations

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 don’t 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...
