site_icons

An efficient website icon scraper for rust or command line usage.

Features

• Super fast!
• Partially downloads images to find the sizes
• Can extract a site logo <img> using a weighing system
• Works with inline-data URIs (and automatically converts <svg> to them)
• Supports WASM (and cloudflare workers)

Command line usage

cargo install site_icons

site-icons https://github.com
# https://github.githubassets.com/favicons/favicon.svg site_favicon svg
# https://github.githubassets.com/app-icon-512.png app_icon png 512x512

# https://github.githubassets.com/apple-touch-icon-180x180.png app_icon png 180x180

Rust usage

use site_icons::Icons;

let mut icons = Icons::new();
// scrape the icons from a url
icons.load_website("https://github.com").await?;

// fetch all icons, ensuring they exist & determining size
let entries = icons.entries().await;

// entries are sorted from highest to lowest resolution
for icon in entries {
  println!("{:?}", icon)
}

Sources

• HTML favicon tag (or looking for default /favicon.ico)
• Web app manifest icons field
• <img> tags on the page, directly inside the header OR with a src|alt|class containing the text "logo"
