Iconoir is an open-source icon library (MIT) providing over 1600 SVG icons in 24×24 grid, distributed as framework-specific packages for React, React Native, Vue, SolidJS, Flutter, and CSS. The repository is a monorepo containing the raw SVG icons, a build pipeline that generates typed component libraries from those SVGs, and a Next.js website for browsing and downloading icons with search, filtering, and customization. The build system (bin/build/index.js) uses a plugin architecture to produce components for each target framework, while the website includes virtualized rendering for performance. Despite the large surface area, the codebase is well-organized with clear separation between icon sources, build tooling, and distribution packages. The primary architectural pattern is code generation: SVGs are transformed into framework-specific components via templates, enabling consistent cross-platform delivery. Notable components include the build pipeline's template system (e.g., icon-template.js), the website's virtualized icon list with React Window, and a Python script for enriching icon metadata from naming conventions.
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.
