MartinXPN / next-slow-build-reproduction

This is a Next.js project bootstrapped with create-next-app.

Steps to reproduce the slow build (#63315)

This repo shows that the latest NextJS version is ~15X slower than the previous one (13.4.19) when building the project.

# You can run `yarn build` instead to see the execution time
npm run build     # (~500s) This will build the app with the latest Next.js version
npm uninstall next && npm install next@13.4.19 && rm -rf .next
npm run build     # (~35s) This will build the app with the previous Next.js version

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.

This project uses next/font to automatically optimize and load Inter, a custom Google Font.
