Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@smarthr/use-bulk-check

npm version

リストに対しての個別チェック・ページ内一括チェック・ページを跨いだ一括全件チェックの状態を管理するための React のカスタムフックです。
バックエンドではチェックした要素の ID 一覧(sting[])かページを跨いだ一括全件チェックのフラグ(boolean)を受け取ることを想定します。

Usage

import React from 'react'
import { useBulkCheck } from '@smarthr/use-bulk-check'

export const Component = () => {
  const users = [
    {
      id: '1',
      name: 'user-1',
    },
    {
      id: '2',
      name: 'user-2',
    },
    {
      id: '3',
      name: 'user-3',
    },
  ]
  const {
    pageItems,
    hasCheckedItemInPage,
    isPageChecked,
    isAllChecked,
    toggleChecked,
    togglePageChecked,
    toggleAllChecked,
    resetChecked,
    checkedIds,
  } = useBulkCheck({ pageItems: users, defaultCheckedIds: ['1', '3'], defaultIsAllChecked: false })

  return (
    <div>
      <ul>
        {pageItems.map(({ item, checked }) => (
          <li key={item.id}>
            <input type="checkbox" checked={checked || isPageChecked || isAllChecked} onChange={() => toggleChecked(item.id)} />
            {item.name}
          </li>
        ))}
      </ul>

      <div>
        <p>
          <input type="checkbox" checked={isPageChecked} onChange={togglePageChecked} />
          ページ内全件チェック
        </p>
        <p>
          <input type="checkbox" checked={isAllChecked} onChange={toggleAllChecked} />
          ページを跨いで全件チェック
        </p>
        <button onClick={resetChecked}>全てのチェック状態を解除</button>
      </div>

      <div>
        <p>
          {hasCheckedItemInPage
            ? '表示しているページ内にチェックされたユーザーが一人以上います'
            : '表示しているページ内のユーザーにはチェックが一つもついていません'}
        </p>
        <p>
          {isPageChecked
            ? '表示しているページ内の全てのユーザーにチェックがついています'
            : '表示しているページ内にチェックがついていないユーザーが一人以上います'}
        </p>
        <p>{isAllChecked && 'ページを跨いで全てのユーザーにチェックがついています'}</p>
      </div>

      <div>
        <p>ページ関係なくチェックされている ID の一覧です。</p>
        <ul>
          {checkedIds.map((id) => (
            <li key={id}>{id}</li>
          ))}
        </ul>
      </div>
    </div>
  )
}
