# Ecosystem

Redux is a tiny library, but its contracts and APIs are carefully chosen to spawn an ecosystem of tools and extensions, and the community has created a wide variety of helpful addons, libraries, and tools. You don't need to use any of these addons to use Redux, but they can help make it easier to implement features and solve problems in your application.

For an extensive catalog of libraries, addons, and tools related to Redux, check out the [Redux Ecosystem Links](https://github.com/markerikson/redux-ecosystem-links) list. Also, the [React/Redux Links](https://github.com/markerikson/react-redux-links) list contains tutorials and other useful resources for anyone learning React or Redux.

This page lists some of the Redux-related addons that the Redux maintainers have vetted personally, or that have shown widespread adoption in the community. Don't let this discourage you from trying the rest of them! The ecosystem is growing too fast, and we have a limited time to look at everything. Consider these the “staff picks”, and don't hesitate to submit a PR if you've built something wonderful with Redux.

## Side Effects

#### Widely Used

**[gaearon/redux-thunk](https://github.com/gaearon/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.

```js
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](https://github.com/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

```js
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](https://github.com/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

```js
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](https://github.com/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

```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](https://github.com/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

```js
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](https://github.com/acdlite/redux-promise)**  
Dispatch promises as action payloads, and have FSA-compliant actions dispatched as the promise resolves or rejects.

```js
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](https://github.com/lelandrichardson/redux-pack)**  
Sensible, declarative, convention-based promise handling that guides users in a good direction without exposing the full power of dispatch.

```js
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 }),
            });
```

## Higher-Level Abstractions

**[keajs/kea](https://github.com/keajs/kea)**  
An abstraction over Redux, Redux-Saga and Reselect. Provides a framework for your app’s actions, reducers, selectors and sagas. It empowers Redux, making it as simple to use as setState. It reduces boilerplate and redundancy, while retaining composability.

**[jumpsuit/jumpstate](https://github.com/jumpsuit/jumpstate)**  
A simplified layer over Redux. No action creators or explicit dispatching, with a built-in simple side effects system.

**[TheComfyChair/redux-scc](https://github.com/TheComfyChair/redux-scc)**  
Takes a defined structure and uses 'behaviors' to create a set of actions, reducer responses and selectors.

**[Bloomca/redux-tiles](https://github.com/Bloomca/redux-tiles)**  
Provides minimal abstraction on top of Redux, to allow easy composability, easy async requests, and sane testability.

## Community Conventions

**[Flux Standard Action](https://github.com/acdlite/flux-standard-action)**
