Usage

Basic Usage

import React, { useEffect } from 'react'
import useFetchData from '@jzone/react-request-hook'
import axios from '@/utils/axios'

export default function TestPages (props) {
  const [{ data, isLoading, error }, fetchData] = useFetchData(data => axios.get('/xxx', { params: data }))
  
  useEffect(() => {
    fetchData()
  }, [fetchData])

  if (!data) {
    return !error ? <div>loading...</div> : <div>error</div>
  }

  return <div>
    <p>hello useFetchData</p>
    <span onClick={() => fetchData({ a: 3 })}>onClick</span>
  </div>
}

Custom Hooks

// hook/index.js
import React from 'react'
import useFetchData from '@jzone/react-request-hook'
import axios from 'axios'
/**
 * @param {*} url url
 * @param {*} initState setInit state, defaultValue: undefined
 * @return {array} [state, memoizedFetchDateApi] state: { data, isLoading, error, ... }
 */
export const useFetchDataGet = (url, initState) => {
  const [state, memoizedFetchDateApi] = useFetchData(data => axios.get(url, { params: data }), initState)

  return [state, memoizedFetchDateApi]
}

/**
 * @param {*} url url
 * @param {*} initState setInit state, defaultValue: undefined
 * @return {array} [state, memoizedFetchDateApi] state: { data, isLoading, error, ... }
 */
export const useFetchDataPost = (url, initState) => {
  const [state, memoizedFetchDateApi] = useFetchData(data => axios.post(url, data), initState)

  return [state, memoizedFetchDateApi]
}

GET

import React, { useEffect } from 'react'
import useFetchData from '@jzone/react-request-hook'
import axios from '@/utils/axios'
import { useFetchDataGet } from '@/hook'

export default function TestPages (props) {
  const [{ data, isLoading, error }, fetchData] = useFetchData(data => axios.get('/xxx', { params: data }))
  // or
  // const [{ data, isLoading, error }, fetchData] = useFetchDataGet('/xxx')
  useEffect(() => {
    fetchData()
  }, [fetchData])

  if (!data) {
    return !error ? <div>loading...</div> : <div>error</div>
  }

  return <div>
    <p>hello useFetchData</p>
    <span onClick={() => fetchData({ a: 3 })}>onClick</span>
  </div>
}

POST

import React, { useEffect } from 'react'
import useFetchData from '@jzone/react-request-hook'
import axios from '@/utils/axios'
import { useFetchDataPost } from '@/hook'

export default function TestPages (props) {
  const [{ data, isLoading, error }, fetchData] = useFetchData(data => axios.post('/xxx', data))
  // or
  // const [{ data, isLoading, error }, fetchData] = useFetchDataPost('/xxx')
  useEffect(() => {
    fetchData()
  }, [fetchData])

  if (!data) {
    return !error ? <div>loading...</div> : <div>error</div>
  }

  return <div>
    <p>hello useFetchDataGet</p>
    <span onClick={() => fetchData({ a: 3 })}>onClick</span>
  </div>
}

Batch Request

function BatchRequest () {
  const batchFetchData = (data) => Promise.all([request1(data), request2(data)])
  const [{ loading, error, data }, fetchData] = useFetchData(batchFetchData)

  useEffect(() => { fetchData() }, [fetchData])

  if (loading) return 'loading...'
  if (error) return 'error'

  const [res1, res2] = data

  return (
    <div>
      <div>{res1}</div>
      <div>{res2}</div>
      <button onClick={() => fetchData({ a: 3 })}>refetch batch</button>
    </div>
  )
}

API

state.isLoading	是否加载中	Boolean or undefined	undefined
state.error	接口请求错误	any	null
fetch	绑定state的请求方法，使用时fetch() 或者 fetch(data)	function(data?)
initState	初始/默认state, e.g: { isLoader: true } 初始为加载中	Object

useFetchData

const [state, fetch] = useFetchData(requestFn[, initState])

参数	说明	类型	默认值
requestFn	自定义请求方法	function(data?)

requestFn e.g:

(data) => fetch('/xxx', { method: 'POST', body: data })
(data) => axios.get('/xxx', {params: data})
(data) => axios.post('/xxx', {params: data})
(data) => Promise(req1(data), req2(data))
...

useFetchDataGet

const [state, fetch] = useFetchDataGet(url[, initState])

参数	说明	类型	默认值
url	请求地址	String

useFetchDataPost

const [state, fetch] = useFetchDataPost(url[, initState])

参数	说明	类型	默认值
