Action mixins

You can add mixins to your actions to handle common tasks. For example, instead of writing:

class LoadText extends AppAction { ...

You can add with CheckInternet to check for internet connectivity:

class LoadText extends AppAction with CheckInternet { ...

Or even combine multiple mixins:

class LoadText extends AppAction with CheckInternet, NonReentrant, Retry { ...

All available mixins

Mixin	Purpose	Overrides
CheckInternet	Checks internet before action; shows dialog if no connection	before
NoDialog	Modifier for CheckInternet to suppress dialog	(requires CheckInternet)
AbortWhenNoInternet	Checks internet before action; aborts silently if no connection	before
NonReentrant	Aborts if the same action is already running	abortDispatch
Retry	Retries the action on error with exponential backoff	wrapReduce
UnlimitedRetries	Modifier for Retry to retry indefinitely	(requires Retry)
UnlimitedRetryCheckInternet	Combines internet check + unlimited retry + non-reentrant	abortDispatch, wrapReduce
Throttle	Limits action execution to at most once per throttle period	abortDispatch, after
Debounce	Delays execution until after a period of inactivity	wrapReduce
Fresh	Skips action if data is still fresh (not stale)	abortDispatch, after
OptimisticCommand	Applies state changes optimistically, rolls back on error	reduce
OptimisticSync	Optimistic updates with coalescing; merges rapid dispatches into one sync	reduce
OptimisticSyncWithPush	Like OptimisticSync but with revision tracking for server pushes	reduce
ServerPush	Handles server-pushed updates for OptimisticSyncWithPush	reduce

Compatibility matrix

Not all mixins can be combined. AsyncRedux throws an exception if you try to use incompatible mixins together, and in some cases it will warn you at compile time.
