This post details The Washington Post's migration to Next.js and Vercel for their election engineering platform. Key technical aspects include: replacing an AWS ECS-based rendering layer with Vercel, migrating to Next.js 12 to utilize Incremental Static Regeneration (ISR), hosting both development and production environments on Vercel, rewriting the frontend in TypeScript, and improving test coverage. The post highlights Vercel's ability to handle spiky traffic and streaming data, enabling scalability and responsiveness. A specific technical challenge addressed was a lagging WebSocket solution for a high-data-load page, which was rewritten successfully. The migration aimed to reduce complexity, improve developer onboarding, and lower costs compared to their previous AWS infrastructure.
