Middleware for syncing redux actions between app instances via pubnub.

Code

import { createStore, applyMiddleware } from 'redux';
import createPubnubActionSyncerMiddleware from 'redux-pubnub-action-sync-middleware';
 
const pubnubMiddleware = createPubnubActionSyncerMiddleware({
    publishKey: 'myPublishKey',
    subscribeKey: 'mySubscribeKey',
});
const createStoreWithMiddleware = applyMiddleware(pubnubMiddleware)(createStore);

createPubnubActionSyncerMiddleware takes an object parameter as input.

This is were to initialize the pubnub connection (pubnub docs)

In addition this object can set additional values for controlling the action syncing;

mode

Possible values 'sender', 'receiver' or 'both' (default)

sender

will only broadcast the actions taken with pubnub, but not apply any actions published by other instances.

receiver

will not broadcast actions taken in the instance, but will apply actions publiched by other instances.

both

will both broadcast and apply received actions.

default value

'both'

sendFilter

Function taking an action and retuning a boolean value. The action will be sendt to the server if the function returns a truethy value.

default value

(action) => true

receiverFilter

Function taking an action and retuning a boolean value. The action will be applied dispatched to the store if the function returns a truethy value.

default value

(action) => true

Query parameter

If mode is not set in code (see above) it can be set by query parameter. Use syncMode=sender, syncMode=receiver or syncMode=both to control the syncing direction.

eg.

http://myapp?syncMode=sender
