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 🙏

介绍

lockman 是一个用于多进程的并发控制锁, 类似一些语言中(比如 C#)的 lock 关键字可以用来确保代码块完成运行,而不会被其他进程「影响」。 它可以把一段代码定义为互斥段(critical section),互斥段在一个时刻内只允许一个进程进入执行, 而其他进程必须等待。

不同之处,C# 的 lock 关键字作用在「线程间」,lockman 作用在 Node 的进程间。

npm version Build Status

安装

$ npm install lockman --save

示例

const Locker = require('lockman');

let locker = new Locker('demo');

locker.acquire(function(){
  //此处代码在同一时刻只允许一个进程进入执行
  locker.release();
});
