From 80fd1d5e9d0b8333601065d8bbaf0858fa5cfdd4 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 16 Feb 2026 10:50:15 +0000 Subject: [PATCH] perf: replace static icon imports with dynamic icon loading in IconifyIcon Removes heavy static imports of entire icon sets (@iconify-json/*) in `client/src/components/base/IconifyIcon.tsx`. Switches to passing icon strings directly to `@iconify/react`'s `Icon` component, which enables on-demand fetching and significantly reduces bundle size. Impact: - Reduces First Load JS for main pages by ~7.7 MB (e.g. /pages/account from 9.09 MB to 1.36 MB). - Eliminates unused icon data from the application bundle.
