SHIP LESS JAVASCRIPT IN NEXT.JS WITH YOUR AI AGENT

Summary from the TLDR Dev newsletter

Hidden import chains often load heavy code upfront that teams thought they had deferred, which slows page loads. Next.js 16.4 adds an agent skill that reads Turbopack's module graph, finds these problems, and can apply the fixes, plus new Bundle Analyzer views for route sizes, snapshot diffs, and the critical render path. At Vercel, it removed nearly 2 MB of compressed JavaScript across v0 and vercel.com, so Turbopack users can get similar savings with little manual work.
