If you've used Vite, you know tree-shaking. It's fast, it's smart, and it runs on every single build — from scratch — every time. That's the part nobody talks about. Today I want to introduce something we've been quietly building inside Ionify: packSlimming . It's our architectural answer to what tree-shaking actually costs at scale. The problem with tree-shaking Tree-shaking is a per-build operation. Every time your build tool runs, it re-analyzes your entire dependency. That analysis disappears when the process exits. Next run? Start over. packSlimming: analysis that lives packSlimming is backed by Ionify's persistent graph and CAS layer. Here's what that means concretely: From your very first cold start, packSlimming analyzes your deps and stores the result. Every subsequent run — whether it's a dev server restart, a production build, or a CI run on the same branch — reuses that analysis. Your deps optimization is live from day one and never repeated unless something actually changes.…
