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

hostc CLI

Expose a local HTTP/WebSocket service through a hostc tunnel.

hostc is the thin command-line product layer on top of the hostc client SDK. It handles arguments, config, diagnostics, terminal output, and local service checks. Protocol logic lives in the shared protocol and client packages.

Install

npm install -g hostc

Or run it without installing:

npx hostc@latest 3000

Usage

hostc <port> [--local-host <host>] [--server <url>] [--data-channels <count>] [--qr]
hostc config get
hostc config set server-url https://hostc.example.com
hostc config unset server-url
hostc config path
hostc doctor [port]

Examples

hostc 3000
hostc 5173 --data-channels 4
hostc 8080 --local-host 127.0.0.1
hostc 3000 --server https://hostc.example.com
hostc 3000 --qr

Options

  • --local-host <host>: host of the local service. Defaults to localhost.
  • --server <url>: hostc server URL. Defaults to https://hostc.dev.
  • --data-channels <count>: number of binary data channel WebSockets. Defaults to 2.
  • --qr: show a QR code for the public URL when stdout is a TTY.

Environment variables

  • HOSTC_SERVER_URL: override the hostc server URL for local development, staging, or self-hosted deployments.
  • HOSTC_CONFIG: override the config file path.
  • HOSTC_DEBUG: set to 1 for protocol and reconnect debug output.
  • HOSTC_DISABLE_UPDATE_CHECK: set to 1 to disable the interactive npm update check.

What it does

  • Creates an ephemeral tunnel.
  • Opens one or more binary data channel WebSockets.
  • Proxies HTTP requests to your local service.
  • Proxies WebSocket upgrades on the same local port.
  • Recreates a new ephemeral tunnel after a data channel disconnect.
  • Prints spinner, success, warning, reconnect reason, and upgrade hints.
  • Provides hostc doctor for local diagnostics.

Current limitations

  • Anonymous tunnels are temporary.
  • Reconnects may create a new tunnel id and public URL.
  • Reserved domains, accounts, dashboard, and daemon mode are not included yet.
  • Early protocol versions may require CLI upgrades.
