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.
