Nix for developers and ops
summary
Nix uses a functional DSL plus a package manager to guarantee reproducible builds via content-addressed derivations and the Nix store. Example converts a Node + puppeteer app to use puppeteer-core and injects Chromium through Nix so builds stop downloading random binaries; the PDF generation runs successfully in a nix-shell environment. Nix provides binary caches to avoid rebuilding huge dependency trees, supports garbage collection of unused store entries, and can export a minimal Docker image.
