vinext starter

Minimal vinext app on Cloudflare Workers with live runtime metrics and build benchmarks.

Live: https://vinext.h1n054ur.dev Article: https://blog.cloudflare.com/vinext/

What this is

Single-route App Router app running on vinext (Next.js API surface reimplemented on Vite), deployed to Workers.

The deployed page:

• Measures live runtime performance in your browser (TTFB, FCP, LCP, transfer sizes)
• Shows local build benchmark results (Next.js Turbopack vs vinext Vite/Rollup)
• Compares both against numbers from the Cloudflare blog post

Results summary

Bundle size (gzipped client JS):

	Next.js	vinext	Delta
CF blog (33 routes)	168.9 KB	74.0 KB	-56%
This repo (1 route)	165.2 KB	71.6 KB	-57%

Bundle reduction checks out.

Build time (3-run mean):

	Next.js	vinext
CF blog (33 routes)	7.38s	4.64s
This repo (1 route)	2.79s	3.40s

Build speed advantage did not reproduce on a single-route app. CF benchmarked 33 routes; the gap likely scales with route count.
