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 🙏

API

Properties

| Name | Type | Default | Description | | ---------------- | --------------------- | --------- | ------------------------------------------------ | | columns | ResizableColumnType[] | undefined | antd table 的 columns | | defaultWidth | number | 120 | 某一列不能拖动,设置该列的最小展示宽度,默认 120 | | minConstraints | number | 60 | 拖动最小宽度 默认 defaultWidth/2 | | maxConstraints | number | Infinity | 拖动最大宽度 默认无穷 | | columnsState | ColumnsStateType | undefined | 列状态的配置,可以用来操作列拖拽宽度 | | onResizeStart | Function | undefined | 开始拖拽时触发 | | onResizeEnd | Function | undefined | 结束拖拽时触发 | | debounceWaitTime | number | 1000 | 窗口resize时重新渲染的防抖时间,单位 ms |

Return

| Name | Description | | ---------------- | --------------------------------------- | | resizableColumns | 拖拽 columns,用在 Table columns | | components | 拖拽 components, 用在 Table components | | tableWidth | 表格宽度,用在 Table width | | resetColumns | 重置 | | refresh | 刷新组件 |

注意事项

  • 默认拖动颜色为#000,可通过global或设置 css 变量--resizable-line-background设置颜色
  • 至少一列不能拖动(width 不设置即可),请保持至少一列的自适应
  • 若 column 未传入dataIndex,请传入一个唯一的key,否则按照将按照 column 的序号 index 计算唯一 key
  • 若 column 有副作用,请把依赖项传入 useMemo deps 中

Example

Antd Table

import { useMemo } from 'react'
import { Table, type TableColumnsType } from 'antd'
import { type ResizableColumnsType, useAntdResizableHeader } from 'use-antd-resizable-header'


type Columns = ResizableColumnsType<TableColumnsType>

function App() {
  const columns: Columns = []

  const { components, resizableColumns, tableWidth, resetColumns, refresh } = useAntdResizableHeader({
    columns: useMemo(() => columns, []),
    // 保存拖拽宽度至本地localStorage
    columnsState: {
      persistenceKey: 'localKey',
      persistenceType: 'localStorage',
    },
  });

  return (
    <>
      <Table
        columns={resizableColumns}
        components={components}
        scroll={{ x: tableWidth }}
      />
    </>
  );
}

ProTable

import { useMemo } from 'react'
import { type ProColumns, ProTable } from '@ant-design/pro-components'

type Columns = ResizableColumnsType<ProColumns[]>


function App() {
  const columns: Columns = []

  const { components, resizableColumns, tableWidth, resetColumns, refresh } = useAntdResizableHeader({
    columns: useMemo(() => columns, []),
  });

  return (
    <>
      <ProTable
        columns={resizableColumns}
        components={components}
        scroll={{ x: tableWidth }}
      />
    </>
  );
}

修改拖拽背景颜色

/* index.css */
--resizable-line-background: red;

为什么需要 React.useMemo ?

如果不使用 useMemo

组件 render => columns 引用变化 => use-antd-resiable-header render => 组件 render => columns 引用变化···

不使用 useMemo

可以采用其他阻止 render 的方案,如: columns 是 prop 或 组件外常量

Table 特殊处理

filter 按钮溢出隐藏了

解决方案

.ant-table-filter-trigger {
  margin-inline: 0;
}

ProTable 特殊处理

fixed

ProTable 默认会给 fixed 列添加宽度,所以可能会造成 至少一列宽度为0 的条件无法满足。

解决方案

  1. 手动给 fixed 列添加宽度,然后不设置其余某一个非 fixed 列宽度
  2. 不设置 fixed 列宽度(默认 200),然后其余某一列也不设置宽度
