Benchmarking Next.js on production

This script allows you to measure some performance metrics of your local build of Next.js on production by uploading your current build to Vercel with an example app and running some basic benchmarks on it.

Requirements

the Vercel CLI

Setup

Rename the provided ./env.local file to ./env and fill in the required VERCEL_TEST_TOKEN and VERCEL_TEST_TEAM values. You can find and generate those from vercel.com.

Run pnpm install, pnpm bench and profit.

Note: if you made some changes to Next.js, make sure you compiled them by running at the root of the monorepo either pnpm dev or pnpm build --force.

How it works

with the Vercel CLI, we setup a project
we npm pack the local Next build and add it to the repo
we upload the repo to Vercel and let it build
once it builds, we get the deployment url and run some tests
