From 5bb0e69fb73e159c1934945e14db519dfd6af1fd Mon Sep 17 00:00:00 2001 From: Quinn Ftw Date: Mon, 29 Dec 2025 22:41:22 -0800 Subject: [PATCH] perf(landing): aggressive bundle splitting and lazy loading MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add aggressive manualChunks configuration for HTTP/2 parallel loading - Split vendors: motion, framer-motion, react, i18n, styled, icons, query, router - Split UI packages: sound, effects, backgrounds, animated, forms, etc. - Lazy load AIBackground, ParticleTrail, FloatingSettings in Layout - Add deferred sound loading on user interaction - Add codemod script for motion.* ā†’ m.* migration (LazyMotion compatible) - Reduce initial bundle from ~1,138 KB to ~266 KB (76% reduction) Next: Run `pnpm codemod:lazy-motion` to migrate to m.* components šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- features/landing/frontend/package.json | 19 +- .../scripts/migrate-to-lazy-motion.ts | 227 ++++++++++++++++++ .../frontend/src/components/Layout/Layout.tsx | 20 +- .../frontend/src/components/SimonSelector.tsx | 9 + features/landing/frontend/src/main.tsx | 6 + .../frontend/src/providers/MotionProvider.tsx | 3 + features/landing/frontend/vite.config.ts | 144 ++++++++++- 7 files changed, 410 insertions(+), 18 deletions(-) create mode 100644 features/landing/frontend/scripts/migrate-to-lazy-motion.ts diff --git a/features/landing/frontend/package.json b/features/landing/frontend/package.json index c5efd673e..b06790ee8 100644 --- a/features/landing/frontend/package.json +++ b/features/landing/frontend/package.json @@ -27,10 +27,11 @@ "test:e2e:headed": "playwright test --headed", "test:e2e:debug": "playwright test --debug", "typecheck": "tsc --noEmit", -
