const app = express(); const unblocker = new Unblocker( prefix: '/proxy/' );

However, you can create a basic implementation using node-unblocker as a middleware within a Vercel-compatible framework like . 1. Project Setup

For personal use, Vercel’s free tier provides ample resources to run basic proxy logic without the overhead of a dedicated VPS.

Ensure node-unblocker is a dependency:

Standard Node Unblocker scripts are designed for long-running processes. To work on Vercel, the code must be refactored into an API route (e.g., /api/proxy ) that exports a handler function rather than listening on a specific port. This requires code modification.
