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 🙏

  • 复用与回收(Recycle)
  • 虚拟化(VirtualWaterfall)

🛡️ 稳健性

  • 书签定位、滚动锚点、粘性头部
  • 状态持久化与 URL 同步

♿ 可访问性与易用性

  • A11y 增强、简洁 API、完善的示例

📊 监控与分析

  • 热力图/交互分析、滚动性能采集(示例插件)

📦 安装

NPM / Yarn / PNPM(作为工程示例运行)

# 安装依赖
npm install

# 启动开发服务器

📊 包大小与优化

模块大小(示意)

| 模块 | 原始大小 | Gzip 后 | 说明 | | ---------- | -------- | ------- | ----------------------------------- | | 核心组件 | ~10 KB | ~3 KB | WaterfallCore 仅包含基础布局逻辑 | | 插件系统 | ~12 KB | ~4 KB | 插件管理器 + 事件总线 | | 单个插件 | ~2-5 KB | ~1-2 KB | 每个插件平均大小 | | 完整插件组 | ~80+ KB | ~25 KB | 包含常用插件的组合示例 |

💡 提示:使用按需导入与插件精简组合,可显著降低打包体积。

Tree-Shaking 支持

本库完全支持 Tree-Shaking,未使用的插件不会被打包到最终产物中。

为什么支持 Tree-Shaking?

  1. ESM 模块发布,便于静态分析
  2. 无副作用标记:"sideEffects": false
  3. 命名导出,便于按需引用
  4. 插件均为独立模块,可单独引入
{
  "sideEffects": false,
  "module": "dist/index.es.js",
  "exports": {
    ".": {
      "import": "./dist/index.es.js",
      "types": "./dist/index.d.ts"
    }
  }
}

✅ 支持 Tree-Shaking 的导入方式

import {
  WaterfallCore,
  withPlugins,
  createAlignmentPlugin,
  createTransitionPlugin,
} from "vane-waterfall";

const Waterfall = withPlugins(WaterfallCore, [
  createAlignmentPlugin({ mode: "shortest" }),
  createTransitionPlugin({ duration: 180 }),
]);

⚠️ 不推荐的导入方式

// ❌ 不推荐:一次性导入所有插件(会失去 Tree-Shaking 优势)
import * as Waterfall from "vane-waterfall";

按需导入示例

方式一:精确导入(最小体积)

import { WaterfallCore, withPlugins, createAlignmentPlugin, createTransitionPlugin } from "vane-waterfall";

方式二:分类导入(推荐)

import {
  WaterfallCore,
  withPlugins,
  createAutoColumnPlugin,
  createResponsiveColumnsPlugin,
} from "vane-waterfall";

方式三:分组导入

import {
  createAlignmentPlugin,
  createFixedHeightPlugin,
  createGapPlugin,
} from "vane-waterfall";

不同场景的包大小对比(示意)

| 使用场景 | 导入插件数 | 预估大小(Gzip) | | -------------- | ---------- | ---------------- | | 最小化(仅核心) | 0 | ~3 KB | | 基础使用 | 2-3 个 | ~8-12 KB | | 常规项目 | 5-8 个 | ~15-25 KB | | 功能丰富 | 10-15 个 | ~30-45 KB |

打包优化建议

1. 使用动态导入

const Waterfall = withPlugins(WaterfallCore, [createTransitionPlugin()]);

async function loadAdvancedPlugins() {
  const { createVirtualWaterfallPlugin } = await import("vane-waterfall");
  return [createVirtualWaterfallPlugin()];
}

2. Vite 配置优化

// vite.config.ts(示例)
export default {
  build: {
    rollupOptions: {
      output: {
        manualChunks: {
          waterfall: ["vane-waterfall"],
        },
      },
    },
  },
};

3. Webpack 配置优化

module.exports = {
  optimization: {
    usedExports: true,
    sideEffects: false,
    splitChunks: {
      cacheGroups: {
        waterfall: {
          test: /vane-waterfall/,
          name: "vane-waterfall",
          chunks: "all",
        },
      },
    },
  },
};

验证 Tree-Shaking 效果

同样可通过打包分析工具或比较测试文件大小的方式进行验证。

性能监控

可通过示例插件采集滚动与布局时序,或在页面中注入简单统计逻辑。


🚀 快速开始

基础使用

import { WaterfallCore } from "vane-waterfall";

<WaterfallCore
  items={items}
  columns={4}
  gap={12}
  padding={12}
  renderItem={(item) => <div style={{ height: item.height }} />}
/>;

使用插件

import {
  withPlugins,
  createAlignmentPlugin,
  createAutoColumnPlugin,
  createResponsiveColumnsPlugin,
  createTransitionPlugin,
} from "vane-waterfall";

const Waterfall = withPlugins(WaterfallCore, [
  createAutoColumnPlugin({ minColumnWidth: 220 }),
  createResponsiveColumnsPlugin({
    breakpoints: {
      xs: { width: 0, columns: 1 },
      sm: { width: 640, columns: 2 },
      md: { width: 768, columns: 3 },
      lg: { width: 1024, columns: 4 },
      xl: { width: 1280, columns: 5 },
    },
  }),
  createAlignmentPlugin({ mode: "shortest" }),
  createTransitionPlugin({ duration: 180, easing: "ease-out" }),
]);

组合示例:性能优化

const WaterfallPerf = withPlugins(WaterfallCore, [
  createTransitionPlugin({ duration: 150 }),
]);

🎯 API 文档

核心组件:WaterfallCore

Props(节选)

| 属性 | 类型 | 说明 | | --------------- | ------------------- | --------------------------------- | | items | any[] | 数据集合(含高度或可测量高度) | | renderItem | (item,i)=>ReactNode | 渲染函数 | | columns | number | 列数(可被插件覆盖) | | gap | number | 列间距 | | padding | number | 容器内边距(参与布局计算) | | alignmentMode | "shortest" | 列分配策略 | | onReachBottom | ()=>void | 触底回调 |

插件钩子(节选)

  • beforeLayoutafterLayout
  • calculateItemPosition(item, index):返回值可覆盖默认位置

🛠️ 开发建议

  • 优先使用 padding 控制容器留白,避免仅用 containerStyle.padding
  • 通过插件扩展行为,保持核心组件简洁稳定
  • 大型场景建议结合虚拟化与工作线程布局
