Project LifeOps (Part 5): 24/7 Zero-Cost Cloud Deployment ($0/month), Mobile Optimization, and PWA
We have arrived at the grand finale of our engineering series. Across the four previous installments, we designed the database architecture and FastAPI backend , crafted the Glassmorphism Dark Mode React interface , built the interactive fitness, reading, cinema, and Kanban modules , and developed the in-memory Word and Excel reporting engine . Yet in software development, a sobering pattern…
In our concluding segment of the engineering series, we demonstrate a groundbreaking, cost-free approach to deploying full-stack applications. This final installment showcases the full LifeOps project, which includes a production-ready cloud topology, a seamless mobile experience, and an installable Progressive Web App (PWA).
1. Production Cloud Topology ($0/month): To ensure continuous availability without any ongoing expenses, we leverage the most generous cloud free tiers available. The client device uses a web browser or an installed Progressive Web App (PWA) accessible via https://datalaria.com/apps/lifeops/. The front end is served through Netlify Edge CDN ($0/month) with Vite build, Rollup code splitting, and transparent proxy rewrite under the Datalaria domain.
The backend runs on Render.com Web Service ($0/month), featuring FastAPI + Uvicorn container, JWT bearer tokens, HTTPS REST calls, anti-DoS rate limiting, and strict CORS. The Supabase Cloud ($0/month) provides a managed PostgreSQL database instance, isolated schema, and cryptographic JWT session validation.
1.1. Vite Bundle Optimization (vite.config.js): To guarantee sub-second initial loads, especially on mobile networks, we configured Rollup manual chunking. This separates stable external dependencies (vendor-react, @supabase, and vendor-libs) from dynamic code, allowing browsers to cache vendor libraries permanently. When updates occur, users only download lightweight changes.
