Vercel System Environment Variable Test

Purpose

This project checks whether Vercel system environment variables (like VERCEL) are available in different build script scenarios.

What We’re Testing

• If VERCEL is available in an npm postbuild script.
• If VERCEL is available when the postbuild script is chained directly in the build command.

How to Test

1. Deploy this project to Vercel.
2. Check the build logs for the output of postbuild.js:
   • First, with postbuild as an npm lifecycle script.
   • Then, by chaining it in the build command:
     "build": "next build && node postbuild.js"

Why

To determine the most reliable way to access Vercel system environment variables during the build process.
