Create tasks to perform effect easier with React Hooks

Install

npm install --save tasook

Overview

React Hooks provide useEffect for perform side effects, but we need :

1. Reduce the boilerplate code when handling async operations
2. Solution to de-couple the trigger & consume of effects, to avoid consume logics in useEffect function, like Dan mentioned in he's twitter

So we build createTask & useTask, to enable us consume data first, then trigger the async operation when need.

Usage

import React, { useEffect } from 'react'
import { effectA, effectB } from './effects';
import { createTasks, createTask, useTask } from 'tasook'

const taskA = createTask(effectA)
const tasks = createTasks({ // create multiple tasks
  effectB,
})

const App = () => {
  // consume task with useTask
  const [dataA, errorA, loadingA] = useTask(taskA)
  const [dataB] = useTask(tasks.effectB)

  useEffect(() => { 
    // only trigger effects in useEffect, do not consume effect results here
    taskA('John') // taskA will pass all arguments to effectA
    tasks.effectB('Kpax')
  }, [])

  return (
    <div>
      hello Tasook
      <div>
        effectA: {dataA}
        <br/>
        effectB: {dataB}
      </div>
      <p>
        <button
          disabled={loadingA}
          onClick={
            () => {
              taskA('Mark@' + (new Date()))
                .then(()=> {
                  console.log('taskA returns what effectA returns')
                })   
            }
          }
        >
          {loadingA ? 'Loading...' : 'Reload effectA'}
        </button>
      </p>
    </div>
  )
}

export default App
