Yarn — 2019 and Beyond
summary
Yarn v2 presents concrete changes: a modular plugin architecture rewritten in TypeScript, Plug’n’Play made the default to eliminate node_modules, replacing tens of thousands of unpacked files with one zip per package and enabling zero-install by committing those zips to the repo. New tools include Yarn DLX for one-off runners, Prolog-based constraints that lint and auto-fix package.json across workspaces, interactive upgrades that resolve workspace version conflicts, revamped message codes and coloured output, and an experimental but usable release path.
