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 🙏

Landlock self-restrict-then-exec launcher for sandboxing subprocesses on Linux: per-platform prebuilt static binaries plus the JS seam that resolves, probes, and speaks their CLI contract

Readme

@deepseek-ai/node-addon-landlock-run

English | 中文

用于在 Linux 上限制子进程的 Landlock「先限制自身、再执行」启动器:此入口包定位对应平台的预构建二进制文件,运行功能性强制执行探测,并构建其授权 argv。消费方无需自行拼写启动器标志或解析启动器输出。

import { grantArgs, launcherPath, probe } from '@deepseek-ai/node-addon-landlock-run';

const launcher = launcherPath();
if (probe(launcher) !== 'unusable') {
  const argv = [launcher, ...grantArgs({ readOnly: ['/'], readWrite: ['/tmp/work'] }), '--', 'bash', '-c', command];
}

启动器在自身上安装 Landlock 规则集,再 exec 被包装的命令;该规则集会跨 execve 继承,因此整个进程树都在限制下运行。未授予的一切都被拒绝;启动器失败时以 125 退出且不运行命令:采用失败闭合策略,绝不在失败时放行。二进制约定锁定在仓库的 docs/cli-contract.md 中;C 源码作为 src/main.c 随该 tarball 分发,便于审计。

平台包(由 os/cpu 选择的可选依赖,内部不含 JavaScript):@deepseek-ai/node-addon-landlock-run-linux-x64@deepseek-ai/node-addon-landlock-run-linux-arm64。在缺少对应包的宿主上,launcherPath() 返回一个固定但不存在的路径,probe() 报告 'unusable';系统有意不提供安装时编译回退。
