Fresh Next.js app benchmark

This fixture is generated by scripts/bench/generate-next-app-fixture.mjs.

Each benchmark run recreates the app, installs current npm versions, and type-checks the generated Next.js project with:

tsz --noEmit -p tsconfig.json
tsgo --noEmit -p tsconfig.json

The app intentionally imports and uses common type-heavy dependencies:

zod
@tanstack/react-query
react-hook-form
type-fest
ts-pattern
superjson
date-fns
clsx
zustand
valibot

The generated source mixes App Router pages, server actions, schema inference, discriminated unions, form helpers, query typing, store typing, and JSON-safe utility types so the benchmark reflects a modern application rather than a tiny startup file.
