+
+Recoil is the next generation state management library: CM safe, memoized, atomic, transactional. [recoiljs.org](https://recoiljs.org)
+
+## ℹ️ Abstract
+`recoil-toolkit` is a set of helpers, patterns and best practices about app state management (`recoil` based) for writing great apps with less effort.
+
+What you get out of the box:
+
+- 📈 task manager
+- ⌚ loading states / loader stacks
+- ❌ error states / error stack
+- :atom: immutable updaters
+- :boom: RecoilTunnel -> read/update a recoilStore outside of React
+- :electron: ReduxTunnel -> mix redux and recoil selectors (gradually upgrade redux apps to recoil!)
+
+and what is coming soon ...
+- 🔜 advanced task manager - chrome dev tools
+- 🔜 easy debugging long/duplicated/onError tasks
+- 🔜 task statistics, kpi
+- 🔜 reactive/observable pattern implementation
+- :question: any idea? open an issue!
+
+...stay tuned!
+
+## 🧰 Installation
+
+```bash
+npm i recoil recoil-toolkit
+# OR
+yarn add recoil recoil-toolkit
+```
+## 📖 Documentation
+
+- [Api guide](https://github.com/salvoravida/recoil-toolkit/tree/master/docs) (work in progress...)
+
+## ❤️ Core Concepts
+*read before the official recoil guide [recoiljs.org](https://recoiljs.org)*
+
+- **Atom**: micro state
+- **Selector** : derived state from atoms and other selectors
+- **Set**: function(microState, prev => next) dispatch micro updates
+- **Task**: async function that do something and can read(get)/write(set) to/from the store.
+
+Simple use pattern with hooks:
+```javascript
+import { useRecoilState, useRecoilValue } from 'recoil';
+import { useRecoilTask } from 'recoil-toolkit';
+
+//in your component ...
+const [state, setState] = useRecoilState(atom);
+const value = useRecoilValue(atomOrSelector);
+//with recoil
+const execute = useRecoilCallback(task,[]);
+//with recoil-toolkit
+const { loading, data, error, execute } = useRecoilTask(task, []);
+```
+
+## ⚙️ State Management Pattern

+--------------------------------------------------------------------
+|                                                                   |
+---> atoms -> selectors -> view(hooks) -> set(sync)/tasks(async) --->
+```
+
+###  🕒 Tasks
+Task is a core concept of `recoil-toolkit`.
+Basically it's an async function (Promise) that have access to the store with a closure of `({ set, reset, snapshot })`.
+
+```javascript
+const task = ({ set, reset, snapshot }) => async ({}) => {
+   // await do something and update store
+};
+   
+function Component(){ 
+    //with recoil
+    const execute = useRecoilCallback(task,[]);
+    //with recoil-toolkit
+    const { loading, data, error, execute } = useRecoilTask(task, []);
+   
+    return ...
+}
+```
+Fetching data example:
+```typescript
+import { atom } from 'recoil';
+import { RecoilTaskInterface, useRecoilTask } from 'recoil-toolkit';
+
+const notifications = atom<{ id: number; text: string }[]>({
+   key: 'notifications',
+   default: [],
+});
+
+const getNotificationsTask = ({ set }: RecoilTaskInterface) => async () => {
+   const body = await fetch('/api/notifications');
+   const resp = await body.json();
+   set(notifications, resp);
+};
+
+export const NotificationsView = () => {
+   const { loading, data, error, execute: refresh } = useRecoilTask(getNotificationsTask, [], {
+      dataSelector: notifications,
+   });
+   if (loading) return 'Loading…';
+   if (error) return 'Sorry! Something went wrong. Please try again.';
+   return (
+      <div>
+         <button onClick={refresh}>Refresh</button>
+         {data.map(({ id, text }) => (
+            <NotificationItem key={id} text={text} id={id} />
+         ))}
+      </div>
+   );
+};
+```
+Sending data example:
+```typescript
+const notificationRead = atomFamily<boolean, number>({
+   key: 'notificationRead',
+   default: false,
+});
+
+const notifyServerNotificationRead = ({ set }: RecoilTaskInterface) => async (id: number) => {
+   await fetch('/api/notification-read', { body: JSON.stringify({ id }), method: 'POST' });
+   set(notificationRead(id), true);
+};
+
+export const NotificationItem = ({ id, text }: { id: number; text: string }) => {
+   const read = useRecoilValue(notificationRead(id));
+   const { loading, error, execute: notify } = useRecoilTask(notifyServerNotificationRead, []);
+   return (
+      <div style={{ color: read ? 'green' : 'yellow' }}>
+         <p>{text}</p>
+         {!read && (
+            <button disabled={loading} onClick={() => notify(id)}>
+               {loading ? 'Sending ...' : 'Send Read'}
+            </button>
+         )}
+         {error && 'Sorry, server error while set notification read!'}
+      </div>
+   );
+};
+```
+### 🔨 Advanced Task Concepts
+Task can have options for advanced use case.
+```typescript
+ type TaskOptions = {
+   key?: string;
+   errorStack?: boolean;
+   loaderStack?: boolean | string;
+   exclusive?: boolean;
+};
+```
+Send error to global errorStack:
+```typescript
+import { useRecoilTask, useLastError } from 'recoil-toolkit';
+
+export const useAdvancedTask = () =>
+   useRecoilTask(advancedTask, [], {
+      errorStack: true,
+   });
+
+// somewhere in your ui ...
+const lastError = useLastError();
+```
+Use a common loader stack:
+```typescript
+import { useRecoilTask, useIsLoading } from 'recoil-toolkit';
+
+export const useAdvancedTask1 = () =>
+   useRecoilTask(advancedTask1, [], {
+      loaderStack: true,
+   });
+   
+export const useAdvancedTask2 = () =>
+   useRecoilTask(advancedTask2, [], {
+      loaderStack: true,
+   });
+
+// somewhere in your ui ...
+const isGlobalLoading = useIsLoading();
+```
+loaderStack can be a string, so you can have many loader stacks if needed.
+```typescript
+export const useAdvancedTask1 = () =>
+   useRecoilTask(advancedTask1, [], {
+      loaderStack: 'widgetA',
+   });
+export const useAdvancedTask2 = () =>
+   useRecoilTask(advancedTask2, [], {
+      loaderStack: 'widgetA',
+   });
+
+// somewhere in your ui ...
+const isWidgetALoading = useIsLoading('widgetA');
+```
+Exclusive tasks (no double run): ComponentA, ComponentB read from the same task instance, that is exclusive. So if componentA already execute the task, componentB, will see the same loading, data, error.
+```typescript
+export const useAdvancedExclusiveTask = () =>
+   useRecoilTask(advancedTask, [], {
+      key:'advancedTask',  
+      exclusive:true   // no double run
+   });
+
+
+function ComponentA(){
+   const {loading, data, error, execute} = useAdvancedExclusiveTask();
+   // ....
+}
+
+function ComponentB(){
+   const {loading, data, error, execute} = useAdvancedExclusiveTask();
+   // ....
+}
+```
+## :boom: RecoilTunnel
+RecoilTunnel capture the current recoil store instance, and allow you to use it outside of React.
+https://codesandbox.io/s/k6ri5
+
+```jsx
+import React from 'react';
+import ReactDOM from 'react-dom';
+import { atom, RecoilRoot, useRecoilValue } from 'recoil';
+import { getRecoilStore, RecoilTunnel } from 'recoil-toolkit';
+
+const timeAtom = atom({
+   key: 'timeAtom',
+   default: new Date(),
+});
+
+export const CurrentTime = () => {
+   const currentTime = useRecoilValue(timeAtom);
+   return <p>{currentTime.toLocaleTimeString()}</p>;
+};
+
+ReactDOM.render(
+   <RecoilRoot>
+      <RecoilTunnel />
+      <CurrentTime />
+   </RecoilRoot>,
+   document.getElementById('root'),
+);
+
+getRecoilStore().then(store => {
+   console.log('RecoilTunnel captured Recoil store:', store);
+   setInterval(() => {
+      store.set(timeAtom, new Date());
+   }, 999);
+});
+```
+
+## :electron: ReduxTunnel
+Read, Write from/to Redux. Mix redux and recoil selectors (gradually upgrade redux apps to recoil!)
+https://zhb1x.csb.app/ - src: https://codesandbox.io/s/zhb1x
+
+```jsx
+import React from 'react';
+import ReactDOM from 'react-dom';
+import { atom, RecoilRoot, useRecoilValue, useRecoilState, selector } from 'recoil';
+import { inc, reduxSelector, ReduxTunnel, useReduxDispatch, useReduxSelector } from 'recoil-toolkit';
+
+//reduxStore is a simple counter { counter:0 }
+import { reduxStore } from './reduxStore';
+const getReduxCount = (s: { count: number }) => s.count;
+
+const counterAtom = atom({ key: 'counter', default: 0 });
+const maxCounterType = selector<string>({
+   key: 'maxCounter',
+   get: ({ get }) => {
+      const re = get(counterAtom);
+      //reduxSelector allow recoil to reactive on redux selector change (memoized)
+      const rx = get(reduxSelector(getReduxCount)) as number;
+      return re === rx ? '' : re > rx ? 'recoil' : 'redux';
+   },
+});
+
+function App() {
+   const reduxCount = useReduxSelector(getReduxCount);  
+   //useReduxSelector it's an alias of useRecoilValue(reduxSelector(sel))
+   //const reduxCount = useRecoilValue(reduxSelector(getReduxCount)); 
+   const dispatch = useReduxDispatch();
+   const [counter, setCounter] = useRecoilState(counterAtom);
+   const maxType = useRecoilValue(maxCounterType);
+   return (
+      <>
+         <div>
+            reduxCounter : {reduxCount}
+            <button onClick={() => dispatch({ type: 'INCREMENT' })}>dispatch</button>
+         </div>
+         <div>
+            recoilCounter : {counter}
+            <button onClick={() => setCounter(inc)}>dispatch</button>
+         </div>
+         <div>{maxType}</div>
+      </>
+   );
+}
+
+ReactDOM.render(
+   <RecoilRoot>
+      <ReduxTunnel reduxStore={reduxStore}>
+         <App />
+      </ReduxTunnel>
+   </RecoilRoot>,
+   document.getElementById('root'),
+);
+```
+Note: you can use `react-redux` useSelector/useDispatch to access reduxStore, instead of useReduxSelector from `recoil-toolkit`, or both at same time.
