webpack

Build performance remains a major concern with 8,511 GitHub issues. Despite being a core Next.js promise, developers struggle with Turbopack, Babel, and webpack optimization. Experimental features often break existing setups, and slow builds cascade to affect all feature delivery timelines.

Developers often start Lambda projects without frameworks, forcing manual setup of API Gateway and CloudWatch integrations. As architectures grow, the 50MB default deployment size limit becomes a constraint, requiring webpack bundling per function to stay under limits and improve deployment speed.
