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 🙏

unix socket for node

Readme

myde-unix-socket

高性能的 Node.js Unix socket 库,使用 Rust (Neon) 实现,支持文件描述符传递 (SCM_RIGHTS)。

特性

  • 🚀 高性能 - 使用 Rust 实现,基于 poll 事件循环
  • 📁 文件描述符传递 - 支持通过 Unix socket 传递文件描述符 (SCM_RIGHTS)
  • 🔍 对方pid获取 - 读取连接对方的 pid,在确认身份时非常有用
  • 📡 事件驱动 - 基于 data 事件接收数据
  • 🏗 TypeScript - 完整的类型定义
  • 📦 开箱即用 - 无需编译/重编译,自带 Linux 兼容二进制

安装

pnpm add myde-unix-socket

快速开始

服务器

import { UServer, USocket } from "myde-unix-socket";

const server = new UServer();
server.listen("/tmp/my-socket");

server.on("connection", (socket) => {
    socket.on("data", (data: Buffer, fds: number[]) => {
        console.log("Received:", data.toString());
    });

    socket.write(Buffer.from("Hello!"));
});

server.resume(); // 开始接受连接

客户端

import { USocket } from "myde-unix-socket";

const client = new USocket("/tmp/my-socket");

client.on("data", (data: Buffer, fds: number[]) => {
    console.log("Received:", data.toString());
});

client.on("connect", () => {
    client.write(Buffer.from("Hello Server!"));
});

事件驱动接收数据

const server = new UServer();
server.listen("/tmp/test");
server.resume();

server.on("connection", (socket) => {
    socket.on("data", (data: Buffer, fds: number[]) => {
        console.log("Data:", data.toString());
        console.log("FDs:", fds);
    });
});

const client = new USocket("/tmp/test");
client.write(Buffer.from("message1"));
client.write(Buffer.from("message2"));

文件描述符传递

import * as fs from "fs";

// 服务器
server.on("connection", (socket) => {
    socket.on("data", (data, fds) => {
        if (fds.length > 0) {
            const content = fs.readFileSync(fds[0], "utf-8");
            console.log(content);
            fs.closeSync(fds[0]);
        }
    });
});

// 客户端
const fd = fs.openSync("/tmp/file.txt", "r");
client.write({ data: Buffer.from("fd"), fds: [fd] });
fs.closeSync(fd);
