Next.js 14 introduced foundational improvements to the App Router framework, incorporating Server Actions, granular revalidation flags, and stream-based partial prerendering. Deploying these workloads on traditional static CDNs often leads to broken hydration or excessive cold starts.

Architecture Overview: ServerLaas Edge Runtime

At ServerLaas, we split the compiled Next.js build output into two optimized tiers: static assets (JS chunks, CSS, public images) are pushed directly to our storage layer and distributed via our edge network, while dynamic SSR routes and Server Actions run in lightweight containerized Node processes monitored by PM2.

bash
# Build configuration inside deploy.sh
npm run build
pm2 reload ecosystem.config.js --update-env
Key Takeaway
Pro Tip: Always ensure NODE_ENV=production is exported before executing next build. Next.js optimizes React bundle sizes by up to 60% in production mode.

Handling Server Actions & Revalidation

Server Actions require atomic consistency between client submit handlers and server execution endpoints. ServerLaas automatically provisions sticky routing headers at the Nginx edge layer to guarantee seamless session state across rolling deployments.
