Usage

Using Redux Subspace with redux-observable is pretty similar to using it with Redux itself, except rather than subspacing the store, you need to subspace the epics.

Epic Middleware

In order for redux-observable to work with redux-subspace you must use the createEpicMiddleware function from the redux-subspace-observable package instead of the default one. This allows redux-subspace to intercept subspaced epics to provide the extra bits it needs to work.

import { createStore } from 'redux'
import { applyMiddleware } from 'redux-subspace'
import { createEpicMiddleware } from 'redux-subspace-observable'
import { reducer, epic } from 'some-dependency'

const epicMiddleware = createEpicMiddleware(epic)

const store = createStore(reducer, applyMiddleware(epicMiddleware))

Subspacing an Epic

The subspaced higher-order epic is used to subspace epics:

import { subspaced } from 'react-redux-observable'
import epic from 'some-dependency'

const subspacedEpic = subspaced((state) => state.subApp, 'subApp')(epic)

Now the epic will only receive actions that match the subspace's namespace and any actions it emits will be automatically namespaced as well.

The store parameter will also be a subspace created by the provided selector and namespace.

Nesting Subspaced Epics

You can nest subspaces epics by combining them together like regular epics. By doing this, the standard nesting behavior of subspaces will still occur.
