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.

Tunki

Self-hosted TCP tunnel for exposing local servers to the internet. A lightweight alternative to ngrok. Single binary for both server and client. Zero dependencies.

Features

Self-hosted: Full control over your data and infrastructure.
Multiplexing: Multiple streams over a single TCP connection.
Resilient: Automatic reconnection and heartbeat monitoring.
Zero Dependencies: Built with standard Node.js libraries.

Installation

npm install -g tunki

Usage

Server

Start the tunnel server on a public machine (e.g., VPS).

tunki server --port 4000

Client

Expose a local HTTP server (e.g., running on port 3000).

tunki http 3000 --server example.com:4000

Expose a local TCP service (e.g., SSH on port 22).

tunki tcp 22 --server example.com:4000

Protocol

Tunki uses a custom binary protocol over TCP.

Control Connection: Persistent connection for signaling and multiplexing.
Frames: Binary frames with header (Type, ID, Length) and payload.
Heartbeat: Periodic PING/PONG frames to ensure connectivity.
