Memory Optimization for SSR

[Uttkarsh-Srivastava]

Summary

• Cache ChunkExtractor in production - Reuse single instance instead of reading/parsing loadable-stats.json on every request
• Cache routes array - Validate and cache routes once at module load instead of per-request
• Add explicit bodyParser limits - Set explicit 100kb limit for json and raw parsers (best practice)

Files Changed

File	Change
src/server/renderer/handler.js	ChunkExtractor & routes caching
src/server/expressServer.js	Explicit bodyParser limits

Why

In production, loadable-stats.json and routes don't change after build. Caching eliminates:

• Repeated JSON file reads and parsing per request
• Redundant route validation per request
• Multiple getRoutes() calls per request
