Changelog

Unreleased

compare

0.6.1 (10.3.2017)

compare

  • Fix :ref on inputs (#259)
  • React updated to 15.4.0 (#275, #276)
  • BREAKING: reagent.core no longer provides render-to-string or render-to-static-markup functions
    • reagent.dom.server includes the same functions
    • This is due to change in React packaging, including React-dom-server would increase the file size considerably, so now it is only included when reagent.dom.server is used

0.6.0

  • React updated to 15.2.1

  • Fix input on-change events in IE11

0.6.0-rc

  • React updated to 15.1.0

  • Symbols and keywords are now allowed in Hiccup content. They are converted using name.

  • Any object hat satisfies IPrintWithWriter is also allowed, and is converted using pr-str.

  • Bug fixes, improved error handling/reporting, and lots of testing.

0.6.0-alpha

Breaking changes

  • Reagent now depends on cljsjs/react-dom and cljsjs/react-dom-server, rather than on cljsjs/react directly.

  • Reactions are now asynchronous, just like Reagent components. flush forces outstanding reactions to run.

  • Reactions now only trigger updates of dependent components if their value change, as reported by = (previously, identical? was used).

  • The macros .' and .! in reagent.interop have been renamed to $ and $! respectively.

News

  • React updated to 0.14.3

  • Added reagent.dom and reagent.dom.server namespaces, corresponding to new React packages.

  • create-class now returns a normal React class, that can be used directly from javascript.

  • Add track: turns a function call into a reactive value.

  • Add track!: eager version of track.

  • Add dispose!: stop the derefable returned by track! from updating.

  • Add with-let macro: simpler handling of lifecycle in components and reactions.

  • Add rswap!: works like swap!, except that recursive calls are allowed, and they always return nil.

  • cursor now shares state between all instances corresponding to a given set of parameters.

  • next-tick now evokes its argument function at a clearly defined time (immediately before rendering, which is in turn triggered using requestAnimationFrame).

  • after-update is a new function, similar to next-tick, except that the function is evoked immediately after rendering.

  • Support [:> nativeComp {:foo "bar"}]

  • Reagent now falls back to using require if global React is undefined, to simplify use with e.g webpack and node.js.

0.5.1

  • React updated to 0.13.3

  • Deprecate calling the result of create-class as a function (i.e always use hiccup forms to call Reagent components).

  • Hiccup syntax has been extended to allow nested elements to be defined using '>' as part of the keyword name.

  • Add force-update for completeness.

  • Try harder to maintain cursor position in inputs.

  • Simplify examples, taking advantage of new figwheel.

  • Better warnings and error messages.

0.5.0

  • React updated to 0.12.2

  • 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.

  • ClojureScript 0.0-2816 or later is required.

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

  • reactify-component makes it easier to use Reagent components in JSX.

  • 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 up some things 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).

  • Reagent now creates all React components using React.createElement (required for React 0.12).

  • 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...
