slack-redux-store

A Redux store that can be used in coordination with node-slack-client. This library implements a set of reducers for real-time events from the Slack API.

Usage

npm install slack-redux-store

import {RtmClient, CLIENT_EVENTS} from '@slack/client';
import SlackReduxStore from 'slack-redux-store';

let client = new RtmClient(yourApiToken, {
  dataStore: new SlackReduxStore(),
  ...
});

client.start();
client.dataStore.subscribe(() => {

  // The store now holds a state tree with the `rtm.start` payload, like:
  // {
  //    users: {},
  //    channels: {},
  //    ims: {},
  //    groups: {},
  //    bots: {},
  //    self: {},
  //    teams: {}
  // }
  //
  // And will be updated with events from the web socket.
  console.log(client.dataStore.getState());
});

You can pass your own reducers, initial state, and enhancers through the constructor, for full customization:

import * as reducers from './your-own-reducers';

let initialState = {
  some: 'defaultState'
};

let enhancers = [
  applyMiddleware(logger),
  DevTools.instrument()
];

return new SlackReduxStore({
  reducers: reducers.default,
  initialState,
  enhancers
});

So What?

If you're using React, your model should be using immutable data for optimal performance. This is because React components rely on shouldComponentUpdate to know when to re-render. You can easily swap out the default store in node-slack-client with this one, which never mutates state.

In addition, this store can leverage extensions like Redux DevTools for monitoring, rewinding, or replaying state changes.
