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 🙏

favicon-generator

A simple CLI tool to generate favicon and PWA icons from a single source image.

Features

  • 🎨 Generates multiple icon sizes from one source image
  • 📱 Creates PWA icons (android-chrome-192x192.png, android-chrome-512x512.png)
  • 🍎 Creates Apple touch icon (apple-touch-icon.png)
  • 🌐 Generates standard favicons (favicon-16x16.png, favicon-32x32.png)
  • 📦 Creates favicon.ico file
  • ⚡ Simple one-command usage

Installation

As a dev dependency (recommended)

npm install --save-dev favicon-generator
# or
pnpm add -D favicon-generator
# or
yarn add -D favicon-generator

Global installation

npm install -g favicon-generator

Usage

  1. Place your source icon as public/source-icon.png in your project root (default)

    • The source image should be square and high resolution (at least 512x512px recommended)
    • PNG format is recommended

  2. Run the generator:

# Default usage (uses public/source-icon.png and outputs to ./public)
npx generate-icons
# or
generate-icons

# Specify a custom input file
npx generate-icons --input ./assets/icon.png
# or
generate-icons -i ./assets/icon.png

# Specify a custom output directory
npx generate-icons --output ./dist/icons
# or
generate-icons -o ./dist/icons

# Both together
npx generate-icons -i ./assets/icon.png -o ./dist/icons

The tool will create the output directory if it doesn't exist.

  1. The following files will be generated in the public/ directory:
    • favicon.ico - Multi-resolution .ico file (16x16, 32x32)
    • favicon-16x16.png - 16x16 favicon
    • favicon-32x32.png - 32x32 favicon
    • apple-touch-icon.png - 180x180 Apple touch icon
    • android-chrome-192x192.png - 192x192 Android Chrome icon
    • android-chrome-512x512.png - 512x512 Android Chrome icon
    • android-chrome-maskable-512x512.png - 512x512 maskable icon
