생태계

Redux는 작은 라이브러리이지만, 그 도구와 확장의 생태계가 널리 퍼져나갈 수 있도록 세심하게 규약과 API를 선택했습니다. 그리고 커뮤니티에서는 다양한 종류의 애드온, 라이브러리, 도구 등을 만들어 왔습니다. Redux를 사용하기 위해 이것들을 꼭 써야 하는 것은 아니지만, 여러분의 앱에서 기능을 구현하고 문제를 해결하는데 많은 도움을 줄 것입니다.

Redux와 관련된 라이브러리, 애드온, 도구에 대한 광범위한 목록을 보고 싶다면 Redux Ecosystem Links을 참고하세요. 또한 React/Redux Links에는 React나 Redux를 배우고 싶은 사람을 위한 튜토리얼과 유용한 자료들이 있습니다.

이 페이지에서는 Redux 메인테이너가 개인적으로 선택했거나, 커뮤니티에 널리 채용된 몇 가지만 소개합니다. 이 목록에 없는 것들도 걱정 말고 써보세요! Redux 생태계는 아주 빠르게 성장하고 있으며, 우리가 전부 써보기에는 시간이 부족했으니까요. 아래 목록은 '개발팀이 추천한' 목록 정도로만 받아들여주세요. Redux와 함께 사용할 수 있는 멋진 도구를 만들었다면 망설이지 말고 풀 리퀘스트를 보내주세요.

KodersLab/topologically-combine-reducers
A combineReducers variation that allows defining cross-slice dependencies for ordering and data passing

{ auth, users, todos },
// define the dependency tree
{ auth: ['users'], todos: ['auth'] }
)

Reducer Composition

// -> { type: 'UPDATE_BAZ_TITLE', id: 1, title: 'Foo Bar Baz', }

Utilities

[subtotalSelector, taxPercentSelector],
(subtotal, taxPercent) => subtotal * (taxPercent / 100)
)

jprichardson/redux-watch
Watch for state changes based on key paths or selectors

let w = watch(() => mySelector(store.getState()))
store.subscribe(
w((newVal, oldVal) => {
console.log(newval, oldVal)

meta: { offline: { effect: {}, commit: {}, rollback: {} } }
})

Immutable Data

ImmerJS/immer
Immutable updates with normal mutative code, using Proxies

const nextState = produce(baseState, draftState => {
draftState.push({ todo: 'Tweet about it' })
draftState[1].done = true
})

Side Effects

Widely Used

reduxjs/redux-thunk
Dispatch functions, which are called and given dispatch and getState as parameters. This acts as a loophole for AJAX calls and other async behavior.

Best for: getting started, simple async and complex synchronous logic.

function fetchData(someValue) {
return (dispatch, getState) => {
dispatch({type : "REQUEST_STARTED"});

myAjaxLib.post("/someEndpoint", {data : someValue})
.then(response => dispatch({type : "REQUEST_SUCCEEDED", payload : response})
.catch(error => dispatch({type : "REQUEST_FAILED", error : error});
};
}

function addTodosIfAllowed(todoText) {
return (dispatch, getState) => {
const state = getState();

if(state.todos.length < MAX_TODOS) {
dispatch({type : "ADD_TODO", text : todoText});
}
}
}

redux-saga/redux-saga
Handle async logic using synchronous-looking generator functions. Sagas return descriptions of effects, which are executed by the saga middleware, and act like "background threads" for JS applications.

Best for: complex async logic, decoupled workflows

function* fetchData(action) {
const { someValue } = action
try {
const response = yield call(myAjaxLib.post, '/someEndpoint', {
data: someValue
})
yield put({ type: 'REQUEST_SUCCEEDED', payload: response })
} catch (error) {
yield put({ type: 'REQUEST_FAILED', error: error })
}
}

function* addTodosIfAllowed(action) {
const { todoText } = action
const todos = yield select(state => state.todos)

if (todos.length < MAX_TODOS) {
yield put({ type: 'ADD_TODO', text: todoText })
}
}

redux-observable/redux-observable

Handle async logic using RxJS observable chains called "epics". Compose and cancel async actions to create side effects and more.

Best for: complex async logic, decoupled workflows

const loginRequestEpic = action$ =>
action$
.ofType(LOGIN_REQUEST)
.mergeMap(({ payload: { username, password } }) =>
Observable.from(postLogin(username, password))
.map(loginSuccess)
.catch(loginFailure)
)

const loginSuccessfulEpic = action$ =>
action$
.ofType(LOGIN_SUCCESS)
.delay(2000)
.mergeMap(({ payload: { msg } }) => showMessage(msg))

const rootEpic = combineEpics(loginRequestEpic, loginSuccessfulEpic)

redux-loop/redux-loop

A port of the Elm Architecture to Redux that allows you to sequence your effects naturally and purely by returning them from your reducers. Reducers now return both a state value and a side effect description.

Best for: trying to be as much like Elm as possible in Redux+JS

export const reducer = (state = {}, action) => {
switch (action.type) {
case ActionType.LOGIN_REQUEST:
const { username, password } = action.payload
return loop(
{ pending: true },
Effect.promise(loginPromise, username, password)
)
case ActionType.LOGIN_SUCCESS:
const { user, msg } = action.payload
return loop(
{ pending: false, user },
Effect.promise(delayMessagePromise, msg, 2000)
)
case ActionType.LOGIN_FAILURE:
return { pending: false, err: action.payload }
default:
return state
}
}

jeffbski/redux-logic

Side effects lib built with observables, but allows use of callbacks, promises, async/await, or observables. Provides declarative processing of actions.

Best for: very decoupled async logic

const loginLogic = createLogic({
type: Actions.LOGIN_REQUEST,

process({ getState, action }, dispatch, done) {
const { username, password } = action.payload

postLogin(username, password)
.then(
({ user, msg }) => {
dispatch(loginSucceeded(user))

setTimeout(() => dispatch(showMessage(msg)), 2000)
},
err => dispatch(loginFailure(err))
)
.then(done)
}
})

Promises

acdlite/redux-promise
Dispatch promises as action payloads, and have FSA-compliant actions dispatched as the promise resolves or rejects.

dispatch({ type: 'FETCH_DATA', payload: myAjaxLib.get('/data') })
// will dispatch either {type : "FETCH_DATA", payload : response} if resolved,
// or dispatch {type : "FETCH_DATA", payload : error, error : true} if rejected

lelandrichardson/redux-pack
Sensible, declarative, convention-based promise handling that guides users in a good direction without exposing the full power of dispatch.

dispatch({type : "FETCH_DATA", payload : myAjaxLib.get("/data") });

// in a reducer:
case "FETCH_DATA": =
return handle(state, action, {
start: prevState => ({
...prevState,
isLoading: true,
fooError: null
}),
finish: prevState => ({ ...prevState, isLoading: false }),
failure: prevState => ({ ...prevState, fooError: payload }),
success: prevState => ({ ...prevState, foo: payload }),
});

Middleware

Networks and Sockets

svrcekmichal/redux-axios-middleware
Fetches data with Axios and dispatches start/success/fail actions

export const loadCategories() => ({ type: 'LOAD', payload: { request : { url: '/categories'} } });

agraboso/redux-api-middleware

const fetchUsers = () => ({

}
})

const actionCreatorsScopedToA = scopeableActions.scope('a')
actionCreatorsScopedToA.foo('bar') //{ type: SET_FOO, value: 'bar', scopeID: 'a' }
