useStream

React hook for repeating async operations.
Source code is hosted on GitHub​
yarn
npm
yarn add @corets/use-stream
npm install --save @corets/use-stream
This library is built on top of these packages:
Async
useAsync
useStream()
Takes a function or an instance of Async and turns it into a repeating stream of data:
import React from "react"
import { createAsync } from "@corets/async"
import { useStream } from "@corets/use-stream"
​
const sharedQuery = createAsync(async () => "some global data")
    
const Example = () => {
  const stream = useStream(1000, async () => `Current date is ${new Date().toISOString()}`)
  const globalStream = useStream(5000, sharedQuery, ["some", "dependencies"])
  
  const handleReload = () => stream.run()
  const handleCancel = () => stream.cancel()
  
  if (stream.isRunning() && ! stream.getResult()) {
    return <h1>Loading for the first time</h1>
  }
  
  if (stream.isErrored()) {
    return <h1>There was an error :(</h1>
  }
  
  return (
    <div>
      Result: {stream.getResult()} 
      {stream.isRunning() && "Refreshing ..."}
      <button onClick={handleReload}>Reload</button>
      <button onClick={handleCancel}>Cancel</button>
    </div>
  )
}
