Major optimizations to resolve Docker build hanging at "rendering chunks..." phase: **Vite Configuration (vite.config.ts)**: - Switch minifier from terser to esbuild (10-100x faster) - Disable sourcemap generation to reduce build time - Implement aggressive chunk splitting for large dependencies: - monaco-editor (73MB) → separate chunk - mermaid (75MB) → separate chunk - @xterm (6.1MB) → separate chunk - vue-vendor, ui-vendor, vendor → logical groupings - Enable CSS code splitting for better caching - Increase chunk size warning limit to 1000KB - Pre-bundle large dependencies (monaco-editor, mermaid, vue, pinia, naive-ui) **Dockerfile Changes**: - Add NODE_OPTIONS=--max-old-space-size=4096 to prevent OOM during build - Move NODE_ENV=production before build step for consistency **Root Cause Analysis**: The build bottleneck was caused by three massive dependencies totaling ~150MB: - monaco-editor (73MB) - VS Code editor for file editing - mermaid (75MB) - Diagram rendering in chat messages - @xterm (6.1MB) - Web terminal These packages caused vite:asset (43%) and vite:terser (8%) phases to take excessive time, especially in resource-constrained Docker environments. **Expected Impact**: - 50-70% faster build times (primarily from esbuild + pre-bundling) - Eliminate hanging at "rendering chunks..." phase - Better memory management during Docker builds Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
