A WebAssembly optimization technique that mounts tar archives as virtual filesystems using JSON metadata indexing, eliminating extraction overhead. WebR has adopted this approach for distributing R packages, achieving faster load times and reduced memory consumption while maintaining compatibility with standard .tar.gz files on static servers.
