svg-sprite is a mature Node.js library and CLI tool for generating SVG sprites from individual SVG files. It supports five output modes (css, view, defs, symbol, stack) and produces accompanying stylesheets (CSS, SCSS, LESS, Stylus) via Mustache templates. The system processes SVGs through a queue-based pipeline that includes SVGO optimization, dimension calculation, namespace handling, and layout algorithms (including a bin-packing algorithm for compact sprites). It is configuration-driven with YAML/JSON support for meta data, alignment, and shape transformations. The codebase is modular with clear separation of concerns: shape processing, sprite layout, mode-specific rendering, and utility functions. It includes a comprehensive test suite with snapshot tests and visual regression testing using Playwright. While the library is actively maintained and well-structured, it carries some technical debt from older JavaScript patterns and a large dependency footprint. The packer algorithm and queue-based processing are standout reusable components.
