+Async error catch middleware for Redux
+
+[![npm version](https://img.shields.io/npm/v/redux-async-catch.svg?style=flat-square)](https://www.npmjs.com/package/redux-async-catch)
+
+```sh
+yarn add redux-async-catch
+```
+
+## Installation
+
+```sh
+yarn add redux-async-catch redux-thunk
+```
+
+Then, update your store configuration:
+
+```js
+import { createStore, applyMiddleware } from 'redux';
+import asyncCatch from 'redux-async-catch';
+import thunk from 'redux-thunk';
+import fetchError from './actions/index';
+import rootReducer from './reducers/index';
+
+const store = createStore(
+  rootReducer,
+  applyMiddleware(
+      // Note: asyncCatch must be applied before thunk
+      asyncCatch(fetchError),
+      thunk
+  )
+
+);
+```
+
+- `asyncCatch` receive a thunk action that will receive catched `error` and `lastAction` as a arguments
+
+## Example
+
+Handle `401` error code in your Application and refresh user token.
+
+```js
+// actions:
+
+export const fetchUserData = () => async function (dispatch, getState) {
+    // You don't need to use try/catch anymore,
+    // all your errors will be handled in fetchError action
+    const user = await fetch('/api/me');
+};
+
+export const refreshUserToken = () => async function (dispatch, getState) {
+    // somme logic
+};
+
+export const fetchError = (e, lastAction) => function (dispatch, getState) {
+    switch (e.status) {
+
+        // when fetchUserData action was called and you got 401 
+        // (user token has been expired), you can refresh token and 
+        // dispatch lastAction again
+        case 401: {
+            dispatch(refreshUserToken());
+            dispatch(lastAction);
+            break;
+        }
+
+        default: {
+            console.error(e);
+        }
+    }
+};
+
+// also you can create your own catch implementation for some actions:
+export const fetchSomeOther = () => async function (dispatch, getState) {
+    try {
+        const user = await fetch('/api/some/other');
+    } catch (e) {
+        if (e.status === '404') {
+            // some logic
+        } else {
+            throw e;
+        }
+    }
+};
+
+```
