HOW WE MADE REGISTRY METADATA 70% SMALLER

Summary from the TLDR Dev newsletter

vlt.io reduces npm registry metadata transfers by serving install-focused packuments that keep fields package managers need while dropping large signatures and checksums that do not affect installation. Across four clean-install fixtures, metadata transfers fell from 25% to 45% of downloaded bytes on npmjs.org to 5% to 15% on vlt.io, with install times improving by 20% to 70%.
