feathers-action

never write another CRUD redux action!

this module helps you use feathers, redux, and tcomb.

Usage

const createModule = require('feathers-action')
const createCid = require('cuid')

const module = createModule('cats')
// module.actions
// module.epic
// module.updater

Dependencies

• feathers-reactive: must add plugin to feathers app / client
• redux-observable: must add middleware to redux store

API

module = feathersAction(name)

module = feathersAction(options)

options:

• name
• methods
• TODO idField

{ actions, updater, epic } = module

• actions: object where keys are method names (find, get, create, ...)
• updater: action => state => nextState
• epic: (action, action$, store) => nextAction$

modules = feathersAction([name, ...])

modules = feathersAction([options, ...])

where modules is an object where key is name and value is module as above.

methodAction = module.actions[method](cid, ...args)

each action creator receives a cid (client-generated id) as the first argument.

all subsequent arguments for feathers methods are the same as the corresponding methods on the feathers service.

completeAction = module.actions.complete(cid)

cancels a long-running subscription as in find or get.

errorAction = module.actions.error(cid, err)

setAction = module.actions.set(cid, key, value)

sets the given key as value in the corresponding redux state.

to unset (remove key), value is undefined.

nextState = module.updater(action)(state)

see "updater" in redux-fp: action => state => nextState

nextAction$ = module.epic(action$, store, { feathers })

see "epic" in redux-observable: (action, action$, store) => nextAction$

must pass in { feathers } as deps to createEpicMiddleware

// client
const Feathers = require('feathers/client')
const feathersSockets = require('feathers-socketio/client')
const feathersRx = require('feathers-reactive')
const Rx = require('rxjs')

const socket = io()
const feathers = Feathers()
  .configure(feathersSockets(socket))
  .configure(feathersRx(Rx))

// store
const { createStore, applyMiddleware } = require('redux')
const { createEpicMiddleware } = require('redux-observable')

const rootEpic = require('./epic')
const rootUpdater = require('./updater')

const epicMiddleware = createEpicMiddleware(rootEpic, {
  dependencies: { feathers }
})

const store = createStore(
  (state, action) => rootUpdater(action)(state),
  applyMiddleware(epicMiddleware)
)

Install

With npm installed, run

$ npm install feathers-action --save
