📝 Walkthrough

Walkthrough

The changes migrate the flamegraph-bench e2e test environment from an Express-based development server to Nitro. The update modifies package.json scripts to run the built Nitro output server, removes the Express dependency, adds nitro as a devDependency, deletes the Express server implementation file, and integrates the Nitro Vite plugin into the build configuration.

Changes

Cohort / File(s)	Change Summary
Nitro Integration e2e/react-start/flamegraph-bench/package.json, e2e/react-start/flamegraph-bench/vite.config.ts	Added nitro (npm:nitro-nightly@latest) as devDependency; modified "start" and "start:prof" scripts to execute ./.output/server/index.mjs instead of ./tests/server.js; integrated nitro() plugin into Vite configuration
Express Server Removal e2e/react-start/flamegraph-bench/tests/server.js	Deleted entire Express server bootstrap file that previously handled static asset serving and request delegation

🐰 Express has served its time so well,
But Nitro's magic breaks its spell!
Now flames dance bright through built output,
Our benchmarks run on swifter strut! ✨
