This repository is a curated collection of over 3400 SVG icons for popular brands, maintained by the Simple Icons project. It is primarily a data repository, with the core assets being the SVG files in `icons/` and the structured metadata in `data/simple-icons.json`. The JSON schema defines brand title, hex color, source URL, guidelines, license, and aliases (including duplicates, localizations, and old names). The repository includes a comprehensive toolchain for managing and validating the icon set: scripts for adding/removing icons, formatting data, and running lint checks (custom linter `ourlint.js`, SVG linting via `svglint`, and JSON schema validation). A JavaScript SDK (`sdk.mjs`) provides utilities for accessing icon data, slug generation, and color normalization. The project is published as an npm package and also served via a CDN. While the primary purpose is data curation, the repository exhibits strong software engineering practices with automated CI/CD (GitHub Actions for release, label sync, issue management), pre-commit hooks, and extensive tests that validate every icon's properties. It is a hybrid of a data collection and a well-engineered toolset for maintaining that collection.
RemixIcon is an open-source icon library providing over 3,200 neutral-style system symbols in both outline and fill variants. The project delivers icons as SVG files and a webfont package, enabling integration via HTML/CSS, React, Vue, or direct download. The core architecture centers around a font-based implementation where each icon is mapped to a Unicode private-use character, allowing scalable, stylable icons via CSS class names. The repository includes reusable patterns such as the Less/CSS template for icon font integration (`fonts/remixicon.less`/`fonts/remixicon.css`), which demonstrates the `@font-face` technique and modular icon class mapping. Additionally, the `tags.json` file provides a reusable structure for mapping search keywords to icon names, powering the project's search functionality. Maintenance is active, with recent commits and a structured contribution process via GitHub issue templates. Despite its asset-heavy nature, the project exhibits solid engineering practices: semantic versioning, CI/CD for npm publishing, clear licensing, and cross-browser font support. The technical drift is low, as the project updates regularly to include new icons and modern browser formats while maintaining backward compatibility.
This repository provides 40+ icon pack libraries for WPF (and UWP) applications under the MahApps.Metro ecosystem. The core architecture defines base classes (PackIconControlBase, PackIconDataFactory, converters) that each icon pack extends with auto-generated code: an enum of icon identifiers (e.g., PackIconFontAwesome6Kind), a PackIcon control, markup extensions, and converters. Icon path data is embedded as JSON resources and loaded via a singleton factory. The code is predominantly auto-generated from upstream icon sets (Font Awesome, Material Design, Bootstrap, etc.), leading to a highly repetitive structure across packs. The library is actively maintained with recent commits, CI/CD pipelines, and semantic versioning. While the code is well-organized and functional, the heavy reliance on code generation reduces craftsmanship in the per-pack files; the genuinely reusable components are the base classes in the Core project, which implement icon scaling, flip, rotation, spin animation, and data loading patterns.
