+ +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: + +- πŸ“ˆ 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 ... +- πŸ”œ advanced task manager - chrome dev tools +- πŸ”œ easy debugging long/duplicated/onError tasks +- πŸ”œ task statistics, kpi +- πŸ”œ 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 +``` +## πŸ“– 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, []); +``` + +## βš™οΈ State Management Pattern + +``` +-------------------------------------------------------------------- +| | +---> atoms -> selectors -> view(hooks) -> set(sync)/tasks(async) ---> +``` + +### πŸ•’ 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 ( +
+ + {data.map(({ id, text }) => ( + + ))} +
+ ); +}; +``` +Sending data example: +```typescript +const notificationRead = atomFamily({ + 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 ( +
+

{text}

+ {!read && ( + + )} + {error && 'Sorry, server error while set notification read!'} +
+ ); +}; +``` +### πŸ”¨ 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

{currentTime.toLocaleTimeString()}

; +}; + +ReactDOM.render( + + + + , + 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.
