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 🙏

@cfp-studio/vfs

@cfp-studio/vfs 提供统一的虚拟文件系统(Virtual File System, VFS)抽象,支持内存、磁盘、堆叠多源读写、监听与快照,适用于低代码、测试、沙箱等多场景。

主要功能

  • 内存文件系统(MemoryReader/Writer)
  • 磁盘文件系统(FsReader)
  • 多源堆叠文件系统(StackedReader)
  • 监听文件变更、快照与回滚
  • 统一 Reader/Writer 接口,支持异步/同步读写

架构与核心模块

  • src/api.ts:Reader/Writer/Entry 等核心接口定义
  • src/memory.ts:内存文件系统实现
  • src/real.ts:真实文件系统实现(基于 fs-extra/chokidar)
  • src/stacked.ts:多源堆叠文件系统实现
  • src/listeners.ts:监听器管理
  • src/index.ts:主入口,导出全部 API 与工厂函数

主要导出 API

  • createMemoryReader():创建内存文件系统
  • createMemoryReaderFromSnapshot(snapshot):基于快照恢复内存文件系统
  • createFileSystemReader(options):创建磁盘文件系统
  • createStackedReader(readers):堆叠多个 Reader
  • Reader/Writer/Entry 等类型

典型用法

import { createMemoryReader, createFileSystemReader, createStackedReader } from '@cfp-studio/vfs';

const mem = createMemoryReader();
const fsr = createFileSystemReader();
const vfs = createStackedReader([mem, fsr]);

依赖

  • fs-extrachokidar:文件系统与监听
  • assert-never:类型安全

构建与测试

  • pnpm build:TypeScript 编译与打包
  • pnpm test:Vitest 单元测试

__ 注意 使用 unbuild @2.0.0 版本 升级后编译错误__
