安装

npm i ph-lock pnpm i ph-lock

export default

// 1. 直接导出
import lock from 'lock'

// 2.导出实例，lockInstance

import {lockInstance} from 'lock'

// lockInstance接收一个参数，表示最大并发数量，0 < num <= 20, 默认 6
const lock = lockInstance(5)

引入

import lock, {lockInstance} from 'lock'
const lock = require('lock')

使用

import lock from 'lock'

const forFn = async (num) => {
  const res = await lock(function() {
    return new Promise(resolve => setTimeout(() => {
      resolve(num)
    }, 5000));
  })
  console.log('end----res:', res);
}

for (let i = 1; i <= 10; i++) {
  forFn(i)
}
