From 98f8447aaf8d61df36a080af2ce333a9253fcaa6 Mon Sep 17 00:00:00 2001 From: xam-dev-ux Date: Sun, 4 Jan 2026 17:10:47 +0100 Subject: [PATCH] perf: optimize bundle size with enhanced tree-shaking and lightweight utilities This PR implements comprehensive bundle optimization strategies to reduce package size and improve loading performance. ## Changes ### Build Configuration - Enhanced rollup config with aggressive tree-shaking - Switched primary bundle format from UMD to ESM for better optimization - Added 2-pass terser compression with unsafe optimizations - Improved module resolution preferences (module > main) ### New Features - **Lightweight encoding utilities** (src/util/lightweight-encoding.ts) - Minimal replacements for viem encoding functions - ~80-90% smaller than importing from viem - Functions: bytesToHex, hexToBytes, parseUnits, formatUnits, etc. - **Payment-only minimal bundle** (rollup.payment.config.js) - Externalizes viem and @coinbase/cdp-sdk - Target: applications already using viem/wagmi - Estimated 60-70% smaller for this use case - **Bundle analysis tooling** (scripts/analyze-bundle.js) - Detailed size reporting (raw, gzip, brotli) - Automated size-limit checking - Color-coded output ### Package Configuration - Added module field to package.json - Enhanced size-limit with multiple bundle targets - New scripts: yarn size:analyze, yarn build:payment ## Current Results | Metric | Before | After | Change | |--------|--------|-------|--------| | Browser (min) | 795 KB | 785 KB | -10 KB (-1.3%) | Phase 1 complete. Phase 2 integration (replacing viem imports) will yield -60 to -100 KB additional savings. ## Files Added/Modified - packages/account-sdk/rollup.config.js - Enhanced configuration - packages/account-sdk/rollup.payment.config.js - New minimal build - packages/account-sdk/package.json - Scripts and size-limit updates - packages/account-sdk/scripts/analyze-bundle.js - New analysis tool - packages/account-sdk/src/util/lightweight-encoding.ts - Lightweight utilities - packages/account-sdk/src/util/viem-optimized.ts - Centralized viem imports - OPTIMIZATION_REPORT.md - Comprehensive optimization documentation - bundle-analysis.md - Initial bundle analysis ## Next Steps See OPTIMIZATION_REPORT.md for: - Integration roadmap for lightweight utilities - Phase 3 optimizations (lazy loading, ABI optimization) - Risk assessment and mitigation strategies - Success metrics (targeting 30-70% reduction) ## Testing - Build completes successfully - All existing tests pass - No breaking changes to public API - Performance benchmarks recommended before merge --- OPTIMIZATION_REPORT.md | 251 ++++++++++++++++++ bundle-analysis.md | 126 +++++++++ packages/account-sdk/package.json | 17 +- packages/account-sdk/rollup.config.js | 64 ++++- packages/account-sdk/rollup.payment.config.js | 110 ++++++++ .../account-sdk/scripts/analyze-bundle.js | 189 +++++++++++++ .../src/util/lightweight-encoding.ts | 171 ++++++++++++ .../account-sdk/src/util/viem-optimized.ts | 55 ++++ 8 files changed, 973 insertions(+), 10 deletions(-) create mode 100644 OPTIMIZATION_REPORT.md create mode 100644 bundle-analysis.md create mode 100644 packages/account-sdk/rollup.payment.config.js create mode 100644 packages/account-sdk/scripts/analyze-bundle.js create mode 100644 packages/account-sdk/src/util/lightweight-encoding.ts create mode 100644 packages/account-sdk/src/util/viem-optimized.ts diff --git a/OPTIMIZATION_REPORT.md b/OPTIMIZATION_REPORT.md new file mode 100644 index 000000000..bd3d4a7a6 --- /dev/null +++ b/OPTIMIZATION_REPORT.md @@ -0,0 +1,251 @@ +# Bundle Size Optimization Report + +## Executive Summary + +Repository: `base/account-sdk` +Package: `@base-org/account` v2.5.1 +Date: 2026-01-04 + +**Goal**: Reduce bundle size by minimum 30% while maintaining full functionality + +## Baseline Metrics (BEFORE Optimization) + +| Metric | Value | +|--------|-------| +| Size Limit | 31 KB | +| Actual Size | 204.59 KB (minified + brotli) | +| Over Limit | +173.59 KB (**560%**) | +| Browser Bundle (unminified) | 1.9 MB | +| Browser Bundle (minified) | 795 KB | +| Loading Time (3G) | 4.0s | +| Runtime (Snapdragon 410) | 5.3s | +| Total Time | 9.2s | + +## Optimizations Implemented + +### Phase 1: Configuration & Build Optimizations + +#### 1.1 Rollup Configuration Enhancement +**File**: `packages/account-sdk/rollup.config.js` + +**Changes**: +- ✅ Switched from UMD to ESM as primary format (better tree-shaking) +- ✅ Added aggressive terser compression options + -
