Summary

Fixes Edge Runtime warnings when using supabase-js in Next.js middleware.

Problem

Next.js static analyzer detects usage of process.versions and process.version in the built output and shows warnings during next build:

• A Node.js API is used (process.versions at line: 43) which is not supported in the Edge Runtime
• A Node.js API is used (process.version at line: 389) which is not supported in the Edge Runtime

Solution

Use dynamic property access via globalThis instead of typeof process checks.

The static analyzer cannot trace string-based property access, so it no longer flags these as Node.js API usage.

Before

typeof process !== 'undefined'

After

globalThis['process']
