Cold install benchmarks from a Next.js 16 + Shadcn/ui + Railway monorepo show pnpm at half npm's time, but the real story is Radix UI's undeclared dependencies breaking under strict hoisting. A practical look at .npmrc tuning, Bun's flat structure trade-off, and where Next.js dependency weight dominates.
An Astro 6 build on Vercel started failing because a generated `_astro/*astro_type_script*` chunk hit an esbuild parse error. Stripping TypeScript syntax was not enough. The stable workaround was to bypass Astro's script transformation path with page-local imports from `public/vendor`.
Rust bundler Rolldown replaces esbuild and Rollup, unifying development and production builds. Achieved 40-64% reduction in actual projects such as Linear and Beehiiv.
