Building a viral application to visualize train routes

What this post added

This post details how Chronotrains, an interactive map visualizing train routes across Europe, leveraged Vercel's platform, including Next.js API Routes deployed as Vercel Functions, to cache "isochrone" results on Vercel's Edge Network for optimal response times and seamless user experience. It also utilized Incremental Static Regeneration to reduce load on its PostgreSQL database, enabling it to scale to thousands of concurrent visitors.
