You mayĮven live without dependency injection, and still be able to test each part of The only place where your isolated and self-contained parts meet is your customĪpplication class (or any other place where you create a global store). Pass the context into theirĬonstructors if needed, let them control the services and other APIs.īut keep them small and isolated. Your middlewares are now your controllers. Join them together and you will get a new state object without producing much The ones that could not handle the message will return the current sub-state, Since reducers byĭefault return the current state - you can easily combine reducer functions.

Handling a subset of actions (and most likely - a sub-state). Your reducer must be pure, but you may split it into smaller functions, each

Your action can be on any type, from raw strings or integer constants to enums forĪuthorization there might be one set of state variables, for user profile Your state can be of any type and it can have any nested sub-states (e.g. Jedux doesn’t force you to implement certain interface or to use certain data Group of action types, so you can use different Enums and use instanceof to see Middlewares are usually small and focused. New Store ( reducer, initialState, new Logger ( 'myApp' ), new Downloader ( context, cacheDir )) toggle the “isDownloading” flag or “progress” value). All actions are passed into the store, where a reducer could update the A thread mayĮmit UPDATE_PROGRESS actions periodically and DOWNLOAD_FINISHED once it’sĭone. Receives that action, starts a downloading thread (or service). On button click you emit START_DOWNLOAD action. Middleware in the chain, and it has a reference to the global store object soĮxample: you need to download a file when the button is clicked.

The action further, or skip it, or emit another action instead.Įach middleware knows about the incoming message, the current state, the next Middleware is a simple way to hook into anĪction stream, intercept actions, run side-effect tasks and either propagate Threads, running network operations or dealing with other android APIs? Now, what if you have to do some real job in your app? Like starting some Your reducer is a pure function that must have no side effects.
