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 🙏

Readme

exfat-reader

一个用于读取 exFAT 镜像(image)的轻量工具库,支持列目录、判断存在与读取文件。

  • 运行环境: Node.js >= 20
  • 包管理器: pnpm (建议),亦可使用 npm/yarn
  • 模块格式: 提供 ESM 与 CJS 构建产物,内置类型声明(.d.ts

安装

# pnpm
pnpm add exfat-reader

# npm
npm i exfat-reader

# yarn
yarn add exfat-reader

快速开始

传入 exFAT 镜像的二进制数据(Uint8ArrayArrayBuffer)。

// ESM
import { ExfatReader, createExfatReader } from "exfat-reader";

// 假设你已经以某种方式获取了 exFAT 镜像的二进制数据
// 例如:从文件、网络、Buffer 等转换为 Uint8Array 或 ArrayBuffer
const imageUint8 = new Uint8Array(/* ... */);

// 方式一:使用类
const reader = new ExfatReader(imageUint8);

// 方式二:工厂函数
// const reader = createExfatReader(imageUint8);

// 列出根目录
const listRoot = reader.list("/");
console.log(listRoot);

// 判断路径是否存在(文件或目录)
console.log(reader.exists("/Documents"));

// 读取文件
const data = reader.readFile("/hello.txt");
if (data) {
  // data 是 Uint8Array,按需转为字符串或写入文件等
  console.log("file size:", data.byteLength);
}

CommonJS 用法

// CJS
const { ExfatReader, createExfatReader } = require("exfat-reader");

const imageUint8 = new Uint8Array(/* ... */);
const reader = new ExfatReader(imageUint8);
console.log(reader.list("/"));
