v3.5

  • Fix a typing bug that made it impossible to use hooks-based (functional) Components with react bridge
  • Bump dependencies to latest version
  • Due to a change in @types/react we can no longer use ActionMap - use ActionMap instead

v3.4

  • Make current state of a store available in store.currentState just as in a BehaviorSubject. This helps in synchronous code (i.e. react state init).

v3.3

  • add useStore() hook to consume a store provided via through new Hooks API

v3.2

  • react bridge: Removed mapStatetoProps function and use much simpler props which is just an Observable emitting the props of the connected component
  • react bridge: Pass down an Observable of the input props given to a connected component
  • react bridge: Remove cleanup return property in connect: subscribe to the store.destroy observable instead which gets called upon unmount
  • react bridge: The store argument passed as the ConnectCallback in the connect() function now calls .clone() on the store internally and automatically calls .destroy() on the clone when the component is unmount. That way we don't need custom cleanup logic inside connect().

v3.0

  • Removed Action type (use Subject and specify a name as 3rd argument to .addReducer() instead)
  • New way of creating slices: Projections. Use .createProjection() to map any properties from a state to another (sliced) state.
  • Add .clone() method to Store which is like a slice without any transformation but uses the same state object. Useful to scope .select()/.watch() subscriptions, as .destroy() will end all subscriptions of the clone but will not affect the original.
  • We do not create immutable copies for initial states anymore but re-use the object passed in as initial state. Create immutable copies yourself if needed before creating a store.
  • Remove fully bundled UMD module from published package, you should use your own bundler like webpack.
  • Requires React >=16.4 for react bridge
  • Switch to reacts new context API for react bridge StoreProvider
  • Drop deprecated lifecycle hooks to be ready for React v17
  • Drop undefined as a valid return type for the ConnectCallback (you can use empty object {} though)

v2.0.0

  • fully RxJS 6 based (without need for rxjs-compat)
  • store.select() now emits on every state change, no matter if the result in the selection function is affected by the changes (disregards shallow identity)
  • introduce store.watch() that works as .select(), but performs a shallow equal check on each state change, not emitting a state if it is shallow-equal to the previous state
  • react bridge: complete change of react connect() API: usage of Components as wrapper now discouraged, everything can be wired inside a single function now passed to connect()
  • react bridge: very strict typing of MapStateToProps and ActionMap types using TypeScript 2.8 conditional types
  • react bridge: is now a first-class citizen: Enzyme based tests with full DOM rendering implemented; react bridge tests contribute to overall code coverage
  • react bridge: Use to provide a store instance via React's context API
  • react bridge: Introduce <StoreSlice slice={state => "keyOfState"}> to create store slices in a declarative way

v1.0.0

  • Fix type-inference for .createSlice() - this breaks existing code (just remove the type argument from .createSlice() to fix). Contributed by Sebastian Nemeth.

v0.5.0

  • React bridge now considered mature and can be imported from 'reactive-state/react'
  • Do not overwrite any initialstate on a slice if that prop is not undefined
  • Breaking change: Do not clone initialState/cleanupState for stores/slices. This means that whatever you pass as initial state object can be modified by the store, and modifications will be visisble to whoever uses that instance. The non-clone behaviour is no coherent with Redux behaviour and allows us to drop a cloneDeep() implementation which save a lot of kilobytes in the output bundle.
  • Better devtool integration with notifyStateChange observable on the store

v0.4.0

  • Use lettable operators from RxJS 5.5
  • Change API for devtool

v0.2.2

  • Fixed tslib only being a dev dependency, although it is needed as runtime dep when included from another project

v0.2.1

  • Fixed .select() not correctly infering the type when given no arguments
  • Fixed behaviour of special cleanup state string "undefined" which would delete they key - This will now set the key on the state to real undefined (non-string) upon cleanup
  • Added a "delete" special cleanup state string that will behave as "undefined" as before (remove the key from the parent state alltogether)
  • Started a changelog.
