Conflux

Conflux (GitHub: ben-ng/conflux, License: MIT, npm: conflux)

Conflux is Redux implantation for distributed systems. As the developer says: Distributed systems are hard. Conflux tries to make distributed systems more understandable. It aims to do what Redux did for Flux, and what Raft did for Paxos. Natrually, it does this by composing the two ideas.

So what does it really do?

You can build serverless applications. Which does not mean “serverless” as in it uses AWS Lambda. Serverless as in there is no central server, like how BitTorrent works just a cluster of nodes that coordinate with each other. The developer let’s know that he is working an a few example applications to help you get going.

A quick example provided by the developer:

var node = conflux({
    id: uuid.v4(),
    // how many nodes are in the cluster?
    clusterSize: 5,
    // how should nodes communicate?
    channel: {
        name: 'redis'
    },
    // define your action creators
    methods: {
        append(thing){
            return thing;
        }
    },
    // define your reducer
    reduce(state, action) {
        state = state == null ? [] : state;
        return state.concat(action);
    },
});

// subscribe to changes
node.subscribe(() => {
    console.log(nodeB.getState().log.join(' '));
});

// perform an action
node.perform('append', ['foo']);

When you have worked with Redux before Conflux should feel very familiar. You subscribe() to a Conflux instance, and call getState() inside to get the current state. Instead of dispatching actions directly, you perform() methods that dispatch() them. The methods are declared when you construct a Conflux instance which is the equivalent to how Action Creators work in Redux.
