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 🙏

ant-virtual-table

English | 简体中文

这是一个ant的虚拟表格,用于解决大数据渲染时页面卡顿的问题,本组件是对ant.desigin中Table组件进行一层封装,属性完全与原组件Table保持一致 AntDesign Table,可以让你像使用普通table一样使用虚拟table。例子中处理渲染1000万条数据,页面也非常流畅。在线demo

设计说明

考虑到兼容性问题,内部通过监听Table的滚动事件判断滑动行的位置,没有采用H5新特性IntersectionObserver。因此兼容性问题是比较好的。另外组件引入loash的throttle处理抖动问题,目前没有采用raf

例子

image

import React, { Component, Fragment } from 'react'
import { VirtualTable } from 'ant-virtual-table'
import 'antd/dist/antd.css'

const columns = [
  {
    title: '序号',
    dataIndex: 'id',
    width: 100
  },
  {
    title: '姓名',
    dataIndex: 'name',
    width: 150
  },
  {
    title: '年龄',
    dataIndex: 'age',
    width: 100
  },
  {
    title: '性别',
    dataIndex: 'sex',
    width: 100,
    render: (text) => {
      return text === 'male' ? '男' : '女'
    }
  },
  {
    title: '地址',
    dataIndex: 'address',
    key: 'address'
  }
]

function generateData () {
  const res = []
  const names = ['Tom', 'Marry', 'Jack', 'Lorry', 'Tanken', 'Salla']
  const sexs = ['male', 'female']
  for (let i = 0; i < 10000000; i++) {
    let obj = {
      id: i,
      name: names[i % names.length] + i,
      sex: sexs[i % sexs.length],
      age: 15 + Math.round(10 * Math.random()),
      address: '浙江省杭州市西湖区华星时代广场2号楼'
    }
    res.push(obj)
  }
  return res
}

const dataSource = generateData()

class App extends Component {
  render () {
    return (
      <Fragment>
        <VirtualTable
          columns={columns}
          dataSource={dataSource}
          rowKey='id'
          pagination={{ pageSize: 40 }}
          scroll={{ y: 400 }}
          bordered
        />
      </Fragment>
    )
  }
}

Prop Types

为降低迁移成本,属性与antd的Table完全保持一致,暂时没有自身独特的属性

注意

目前暂不支持内嵌tree等复杂的表单结构,任何复杂的表单结构都不建议使用,后续跟进当中...
