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 🙏

数据结构

基本任务结构

export type Task = {
  id: string;
  type: TaskType; // 'task' | 'project' | 'milestone'
  name: string;
  start: Date;
  end: Date;
  progress: number; // 0-100
  styles?: {
    backgroundColor?: string;
    backgroundSelectedColor?: string;
    progressColor?: string;
    progressSelectedColor?: string;
  };
  isDisabled?: boolean;
  project?: string; // 向后兼容的字段
  dependencies?: string[];
  hideChildren?: boolean;
  displayOrder?: number;
  children?: Task[]; // 新的嵌套结构
};

任务组织方式

1. 传统方式(向后兼容)

使用 project 字段来标识任务属于哪个项目:

const tasks: Task[] = [
  {
    id: 'Project1',
    name: '项目1',
    type: 'project',
    start: new Date('2024-01-01'),
    end: new Date('2024-01-31'),
    progress: 50,
  },
  {
    id: 'Task1',
    name: '任务1',
    type: 'task',
    start: new Date('2024-01-01'),
    end: new Date('2024-01-10'),
    progress: 80,
    project: 'Project1', // 通过 project 字段关联
  },
];

2. 新的嵌套结构(推荐)

使用 children 数组来组织任务,支持多层级嵌套:

const tasks: Task[] = [
  {
    id: 'SoftwareProject',
    name: '软件开发项目',
    type: 'project',
    start: new Date('2024-01-01'),
    end: new Date('2024-01-31'),
    progress: 30,
    hideChildren: false,
    children: [
      {
        id: 'Planning',
        name: '项目规划',
        type: 'task',
        start: new Date('2024-01-01'),
        end: new Date('2024-01-05'),
        progress: 100,
        children: [
          {
            id: 'Requirements',
            name: '需求分析',
            type: 'task',
            start: new Date('2024-01-01'),
            end: new Date('2024-01-03'),
            progress: 100,
          },
          {
            id: 'Design',
            name: '系统设计',
            type: 'task',
            start: new Date('2024-01-03'),
            end: new Date('2024-01-05'),
            progress: 80,
            dependencies: ['Requirements'],
          },
        ],
      },
      {
        id: 'Development',
        name: '开发阶段',
        type: 'project',
        start: new Date('2024-01-05'),
        end: new Date('2024-01-25'),
        progress: 20,
        children: [
          {
            id: 'Frontend',
            name: '前端开发',
            type: 'task',
            start: new Date('2024-01-05'),
            end: new Date('2024-01-15'),
            progress: 30,
            dependencies: ['Design'],
          },
          {
            id: 'Backend',
            name: '后端开发',
            type: 'task',
            start: new Date('2024-01-07'),
            end: new Date('2024-01-20'),
            progress: 15,
            dependencies: ['Design'],
          },
        ],
      },
    ],
  },
];

嵌套结构的优势

  1. 更直观的组织方式:任务层级关系一目了然
  2. 支持多层级嵌套:可以创建复杂的项目结构
  3. 更好的代码可读性:数据结构更清晰
  4. 向后兼容:仍然支持传统的 project 字段
  5. 自动缩进显示:任务列表会根据层级自动缩进

安装

npm install react-gantt-chart
# 或
yarn add react-gantt-chart
# 或
pnpm add react-gantt-chart

基本使用

import React from 'react';
import { Gantt } from 'react-gantt-chart';
import { ViewMode } from 'react-gantt-chart';

const App = () => {
  const tasks = [
    {
      id: 'Task1',
      name: '任务1',
      type: 'task',
      start: new Date('2024-01-01'),
      end: new Date('2024-01-10'),
      progress: 50,
    },
    // ... 更多任务
  ];

  const handleTaskChange = task => {
    // 使用 debug 包进行调试
    const debug = require('debug')('react-gantt:example');
    debug('任务变更:', task);
  };

  return (
    <Gantt
      tasks={tasks}
      viewMode={ViewMode.Day}
      onDateChange={handleTaskChange}
      listCellWidth="155px"
      columnWidth={65}
    />
  );
};

高级功能

任务展开/折叠

const handleExpanderClick = task => {
  // 处理任务展开/折叠
  const debug = require('debug')('react-gantt:example');
  debug('展开/折叠任务:', task);
};

<Gantt
  tasks={tasks}
  onExpanderClick={handleExpanderClick}
  // ... 其他属性
/>;

自定义样式

<Gantt
  tasks={tasks}
  barBackgroundColor="#b8c2cc"
  barProgressColor="#a3a3ff"
  projectBackgroundColor="#fac465"
  milestoneBackgroundColor="#f1c453"
  // ... 其他样式属性
/>

国际化

<Gantt
  tasks={tasks}
  locale="zh-CN" // 支持中文
  // ... 其他属性
/>

子任务显示控制

<Gantt
  tasks={tasks}
  showSubTask={true} // 显示子任务行
  // ... 其他属性
/>

<Gantt
  tasks={tasks}
  showSubTask={false} // 隐藏子任务行(默认)
  // ... 其他属性
/>

迁移指南

从传统结构迁移到嵌套结构

  1. 识别项目任务:找到所有 type: 'project' 的任务
  2. 收集子任务:找到所有 project 字段指向该项目的任务
  3. 重构数据结构:将子任务放入项目的 children 数组中
  4. 移除 project 字段:从子任务中移除 project 字段(可选)
// 迁移前
const oldTasks = [
  { id: 'Project1', name: '项目1', type: 'project', ... },
  { id: 'Task1', name: '任务1', type: 'task', project: 'Project1', ... },
  { id: 'Task2', name: '任务2', type: 'task', project: 'Project1', ... },
];

// 迁移后
const newTasks = [
  {
    id: 'Project1',
    name: '项目1',
    type: 'project',
    children: [
      { id: 'Task1', name: '任务1', type: 'task', ... },
      { id: 'Task2', name: '任务2', type: 'task', ... },
    ],
  },
];
