  • :before-render should be called on server-side rendering too (thx Alexander Solovyov, #79)

0.10.0

A big cleanup/optmization/goodies release with a lot breaking changes. Read carefully!

  • [ BREAKING ] cursor got renamed to cursor-in. New cursor method added that takes single key (as everywhere in Clojure)
  • [ BREAKING ] rum/mount returns nil (because you shouldn’t rely on return value of ReactDOM.render)
  • [ BREAKING ] :transfer-state is gone. All of component’s state is now transferred by default. If you still need to do something fancy on componentWillReceiveProps, new callback is called :did-remount callback
  • [ BREAKING ] removed cursored and cursored-watch mixins. They felt too unnatural to use
  • [ BREAKING ] removed rum/with-props (deprecated since 0.3.0). Use rum/with-key and rum/with-ref instead
  • [ BREAKING ] server-side rendering no longer calls :did-mount (obviously, that was a mistake)
  • [ BREAKING ] :rum/id is gone. If you need an unique id per component, allocate one in :init as store it in state under namespaced key

When upgrading to 0.10.0, check this migration checklist:

  • Change all rum/cursor calls to rum/cursor-in
  • Find all :transfer-state mixins.
    • If the only thing they were doing is something like (fn [old new] (assoc new ::key (::key old))), just delete them.
    • If not, rename to :did-remount
  • Check if you were using rum/mount return value. If yes, find another way to obtain component (e.g. via ref, defcc etc)
  • Replace rum/with-props with rum/with-key, rum/with-ref or :key-fn
  • Check that you weren’t relying on :did-mount in server-side rendering

Now for the good stuff:

  • Cursors now support metadata, alter-meta! etc
  • Cursors can be used from Clojure
  • Added :key-fn to mixins. That function will be called before element creation, with same arguments as render fn, and its return value will be used as a key on that element
  • Mixins can specify :before-render (triggered at componentWillMount and componentWillUpdate) and :after-render (componentDidMount and componentDidUpdate) callback
  • Added rum/ref and rum/ref-node helpers, returning backing component and DOM node
  • Some client-side API functions added to server version (dom-node, unmount, request-render etc). Their implementation just throws an exception. This is to help you write less conditional directives in e.g. :did-mount or :will-unmount mixins. They will never be called, but won’t stop code from compiling either.

And couple of optimizations:

  • Rum now makes use of staless components (nothing for you to do, if your component is defined via defc with no mixins, it’ll be automatically compiled to stateless component)
  • Rum will use React’s batched updates to perform rendering on requestAnimationFrame in a single chunk
  • Streamlined internals of component construction, removed render->mixin, args->state, element and ctor->class

0.9.1

  • Added rum.core/derived-atom, a function that let you build reactive chains and directed acyclic graphs of dependent atoms. E.g. you want *c to always contain a value of *a plus a value of *b and update whenever any of them changes
  • Added rum.core/dom-node helper that takes state and finds corresponding top DOM node of a component. Can be called in mixins after initial render only
  • Fixed compatibility of with-key on nil-returning component in server rendering (thx Alexander Solovyov, #73)

0.9.0

  • Better support for server-side rendering of SVG
  • [ BREAKING ] Rum used to support multiple ways to specify attributes. You would expect that both :allow-full-screen, :allowFullScreen and "allowFullScreen" would be normalized to allowfullscreen. As a result, you have to face three problems:
    • how do I decide which variant to use?
    • how do I ensure consistency accross my team and our codebase?
    • find & replace become harder

Starting with 0.9.0, Rum will adopt “There’s Only One Way To Do It” policy. All attributes MUST be specified as kebab-cased keywords:

Attribute What to use What not to use
class :class :class-name :className
for :for :html-for :htmlFor
unescaped innerHTML :dangerouslySetInnerHTML { :__html { "..." }}
uncontrolled value :default-value :defaultValue
uncontrolled checked :default-checked :defaultChecked
itemid, classid :item-id, :class-id :itemID :itemId :itemid
xml:lang etc :xml-lang :xml/lang :xmlLang "xml:lang"
xlink:href etc :xlink-href :xlink/href :xlinkHref "xlink:href"
xmlns not supported

To migrate to 0.9.0 from earlier versions, just do search-and-replace for non-standard variants and replace them with recommended ones.

0.8.4

  • Improved server-side rendering for inputs (#67 & beyond)
  • Compatible server-side rendering of components that return nil (#64)
  • Upgraded React to 15.1.0

0.8.3

  • rum/render-static-markup call for pure HTML templating. Use it if you’re not planning to connect your page with React later
  • rum/def* macros now correctly retain metadata that already exists on a symbol (thx aJchemist, #62)

0.8.2

  • Add rum.core/unmount function (thx emnh, #61)

0.8.1

  • Retain :arglists metadata on vars defined by rum/def* macros (thx aJchemist, #60)

0.8.0

  • Migrated to React 15.0.1
  • Optimized server-side rendering (~4× faster than Rum 0.7.0, ~2-3× faster than Hiccup 1.0.5)

0.7.0

0.6.0

0.5.0

  • Added :class-properties to define arbitrary properties on a React class (thx Karanbir Toor, #44)
  • [ BREAKING ] Removed support for :child-context-types and :context-types. Use { :class-properties { :childContextTypes ..., :contextTypes ... } } instead.

0.4.2

0.4.1

  • Fixed bug with rum macros emitting wrong namespace. You can now require rum.core under any alias you want (thx Stuart Hinson, #42)

0.4.0

  • [ BREAKING ] Core namespace was renamed from rum to rum.core to supress CLJS warnings

  • New defcc macro for when you only need React component, not the whole Rum state
  • [ BREAKING ] Component inner state (:rum/state) was moved from props to state. It doesn’t change a thing if you were using Rum API only, but might break something if you were relaying on internal details
  • Deprecated rum/with-props macro, use rum/with-key or rum/with-ref fns instead

0.2.7

  • Allow components to refer to themselves (thx Kevin Lynagh, #30)
