Modern Tar Archiver

modern-tar is a zero-dependency, cross-platform JavaScript library designed for efficient streaming of tar archives. It supports both parsing and writing tar files, leveraging the browser-native Web Streams API for optimal performance and memory efficiency across diverse JavaScript runtimes, including Node.js (requiring version 18.0.0 or higher), web browsers, and Cloudflare Workers. The library is currently at stable version 0.7.6, with a consistent release cadence that introduces bug fixes, performance optimizations, and crucial security patches. Its key differentiators include a robust streaming architecture capable of handling large archives without full memory loading, full compliance with USTAR format and PAX extensions, built-in helpers for gzip compression, a TypeScript-first design ensuring strong type safety, and a minimal footprint due to its zero external dependencies.
