createSessionReducer

Handy for creating the reducer that repacks and pushes the Session to Redux Store State.

Note this requires the input Action to fit the description in: ActionObject

function createSessionReducer (actionType, sessionObject)

Usage:

const session = { data: 'data' }

const reducer = createSessionReducer('reducer:sample:update', session) // Repack Session and Update the Store State

const service = function * ({ store, req, res }) {
  yield req('service:sample:init')
  while (true) {
    yield res({ type: 'reducer:sample:update', payload: session }) // Send the Update Action with latest Session
    const action = yield req([ 'service:sample:one', 'service:sample:two' ])
    // codes with access to action, session, store
  }
}

The (really simple) source code:

function createSessionReducer (actionType, sessionObject) {
  const initialState = { ...sessionObject, _tick: 0 }
  return (state = initialState, action) => {
    if (action.type === actionType) return { ...state, ...action.payload, _tick: state._tick + 1 }
    else return state
  }
}
