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.

Double clap to activate JARVIS — plays a welcome sound and opens Terminal

jarvis-clap

Double clap to activate JARVIS — plays a welcome sound and opens Terminal. Just like Tony Stark.

Install

# Prerequisite
brew install sox

# Install JARVIS
npm install -g jarvis-clap

Usage

# Run in foreground
jarvis

# Install as auto-start service (runs on login)
jarvis install

# Check status
jarvis status

# Remove the service
jarvis uninstall

Options

# Adjust clap sensitivity (0.0 = hair trigger, 1.0 = thunder only)
jarvis --threshold 0.5

# Use a custom sound file
jarvis --sound ~/my-sound.mp3

How it works

JARVIS listens to your MacBook microphone via sox. When it detects two sharp sounds (claps) within 0.1–0.5 seconds of each other, it:

Plays the welcome sound through your MacBook speakers
Opens Terminal

Detection is paused for 10 seconds after each trigger to prevent the sound playback from re-triggering.

Requirements

macOS (uses CoreAudio, afplay, and osascript)
Node.js >= 16
sox — brew install sox

Troubleshooting

Not triggering? Lower the threshold: jarvis --threshold 0.2

Triggering on random noise? Raise it: jarvis --threshold 0.5

No sound playing? Check your output device in System Settings > Sound.
