0.3.1-alpha

• upgrade prop-types dependency (#20)
• use :static-properties instead of :class-properties to pass :childContextTypes (#20)

0.3.0

• ⚠️ Breaking derivatives-pool now returns the record instead of a map with the get! and release! functions. If you did not directly call the derivatives-pool function (and used the Rum mixins) this should not affect you. (e813f1ddfd7)
  • To upgrade replace uses of the get! and release! functions with their pendants in org.martinklepsch.derivatives (same names) and pass the derivatives pool record that is now returned by derivatives-pool as first argument.
  • Sorry for this breakage I hope it does not affect too many. 🙌
• Improvement depend on cljsjs/react-proptypes for React 16 compatibility (#18)
• Bugfix with a spec like {:db [[] (atom {})]} it was not possible to get ahold of the :db atom. (64efb6f3)

0.2.0

• Improvement Implement own derived-value that can be disposed, which will remove watches on sources (atoms or other watchable things). Previously Rum's derived-atom was used which does not support cleaning up watches when they are no longer needed. PR #2

• New Feature Extend Rum drv mixin to accept multiple arguments PR #5 & PR #8. Previously you called d/drv multiple times:

  (rum/defcs block < rum/reactive (d/drv :product/page) (d/drv :product/images) (d/drv :product/text) 
    [state]
    (let [page   (d/react state :product/page)
          images (d/react state :product/images)
          text   (d/react state :product/text)] 
      ...))

  Now it is possible to pass multiple keywords to the same function with the same result as multiple invocations. Also there is a new function react-all that can be used to dereference multiple or all known derivatives at once:

  (rum/defcs block < rum/reactive (d/drv :product/page :product/images :product/text)
    [state]
    (let [{:keys [:product/text]} (d/react-all state)]
      [:p text] ,,,))

  (d/react-all state) -> {:product/page 'val :product/images 'val :product/text 'val}
  (d/react-all state :product/page) -> {:product/page 'val}

• Improvement The sync-derivatives! function and the DerivativesPool record constructors now receive an extra argument watch-key-prefix that helps avoiding conflicts when creating multiple pools from a single source atom with specs that have overlapping keys. See #10 for details.

  • This change is breaking if you call ->DerivativesPool, map->DerivativesPool or sync-derivatives! directly. Most likely you are not though :)

• Bugfix Fix wrong assumption in tests that would cause them to fail when a spec contains more complex keys: 37cda80

• Bugfix Fix issue where sync-derivatives! would fail if spec keys don't implement IFn b5f9545

0.1.1

• add tests

• implement build in terms of sync-derivatives

• add assertions that spec is a map

• when checking if something is a function to use to derive a new value or if it is a source we now use (implements? IWatchable x) instead of (fn? x)

• refactor pooling implementation to allow testing of internals

• Rum mixins: simplifiy keys used in childContext to be strings

• Rum mixins: make sure the token is correctly passed to get! and release! functions

0.1.0 (04-06-2016)

• initial release

Legend

• Breaking: A refactoring that may potentially break backwards compatibility
• Improvement: An improvement that is not breaking compatibility and thus should not require action from your side
• New Feature: An extension to the API that may make your life easier
• Bugfix: Fix of broken behavior. If you think you might rely on the bug check the linked commit.
