redux-substore

Collected actions, reducer, epic and state for any async operation.

Install

npm install redux-substore --save

Run the demo!

npm run demo

The demo shows how redux-substore can manage two types of requests: one that succeeds and one that fails.

How to use it:

Setup

Construct a new Substore that will manage the getMyData() request function.

import Substore from 'redux-substore'

export default new Substore({
  prefix: 'MY_PREFIX',
  promiseFunction: args => getMyData(args),
  responseMap: response => response['keyWhereMyDataIs'],
})

The prefix will be used to label the action types for this substore. The function passed to promiseFunction: must return a promise that will resolve with the response or reject with an error. Alternatively, send callbackFunction: with a Node-style callback with signature function(err, data). The responseMap: function will receive whatever the request function resolves or calls back with, and should use the response to generate the substore's state. responseMap should generate the initialState for the substore when it receives null.

Integrate with Redux

Add the reducer and epic to your combineReducers and combineEpics:

import { combineReducers } from 'redux'

rootReducer = combineReducers({
    ...
    myData: myDataSubstore.reducer
})

import { combineEpics } from 'redux-most'

rootEpic = combineEpics([
    ...
    myDataSubstore.epic
])

Manage Your Async Ops

Trigger the request by dispatching the result of requestAction()

store.dispatch(mySubstore.requestAction(requestParams))

Parameters passed to the requestAction will be passed on to the request function supplied as promiseFunction: or callbackFunction: when the Substore was constructed. The action has type MY_PREFIX_REQUEST and when it completes, MY_PREFIX_REQUEST_SUCCESS or MY_PREFIX_REQUEST_FAILURE will be dispatched accordingly.

Access the status and data of the substore by selecting the key you assigned in combineReducers:

getState().myData.isLoading

getState().myData.error

getState().myData.data (default responseMap sets this key)

Clean up

If you need to remove the data in the Substore, dispatch mySubstore.clearAction().
