| ## React-ProviderX | ||
|
|
||
| A React state management library built on top of RxJS and Observables | ||
|
|
||
| ## Usage: | ||
|
|
||
| The library will cache data within your ObservableProvider, so you can grab values from a provider with the `useProvider` | ||
| hook - without re-fetching data. | ||
|
|
||
| ```tsx | ||
| import React from 'react' | ||
| import { useProvider, ObservableProvider, refresh } from 'react-providerx' | ||
| import { from } from 'rxjs' | ||
| import { tap } from 'rxjs/operators' | ||
|
|
||
| export const userResponseProvider$ = ObservableProvider.autoDispose((ref) => { | ||
| const fetchErrorApi = async () => { | ||
| const response = await fetch('https://jsonplaceholder.typicode.com/users/1') | ||
| const json = await response.json() | ||
| return json | ||
| } | ||
|
|
||
| return from(fetchErrorApi()).pipe( | ||
| catchError((error: Error) => { | ||
| console.log('there was an error in fetching the api') | ||
| ref.maintainState = false | ||
| return throwError(error) | ||
| }), | ||
| ) | ||
| }) | ||
| const fetchErrorApi = async () => { | ||
| const response = await fetch('https://jsonplaceholder.typicode.com/users/1') | ||
| const json = await response.json() | ||
| return json | ||
| } | ||
|
|
||
| return from(fetchErrorApi()).pipe( | ||
| catchError((error: any) => { | ||
| ref.maintainState = false | ||
| return ref.error(error) | ||
| }) | ||
| ) | ||
| }) | ||
|
|
||
| const Component: React.FC = () => { | ||
| const { isLoading, data, error } = useProvider(userResponseProvider$) | ||
| if(isLoading) { | ||
| return ( | ||
| <div> | ||
| Waiting For Data... | ||
| </div> | ||
| ) | ||
| } | ||
| return ( | ||
| <div> | ||
| {data} | ||
| <button onClick={() => refresh(userResponseProvider$)}>Click to refresh</button> | ||
| </div> | ||
| ) | ||
| const { isLoading, data, error } = useProvider(userResponseProvider$) | ||
| if (isLoading) { | ||
| return <div>Waiting For Data...</div> | ||
| } | ||
| return ( | ||
| <div> | ||
| {data} | ||
| <button onClick={() => refresh(userResponseProvider$)}> | ||
| Click to refresh | ||
| </button> | ||
| </div> | ||
| ) | ||
| } | ||
