Deploying Node Unblocker on Vercel is a common way to create a personal proxy for bypassing simple network filters. However, because Vercel uses Serverless Functions rather than persistent servers, you need a specific configuration to make it work. 🚀 Deployment Guide

Deployment Steps — Minimal Proxy Example (function-based)

Assumptions: You will implement a constrained proxy function using Vercel Serverless Functions or Edge Functions (Edge recommended for low-latency, but memory/time smaller). The example below is conceptual — adapt to your repo layout and Vercel config.

Push your code to GitHub and import the repository into the Vercel Dashboard, or use the Vercel CLI: vercel Use code with caution. Copied to clipboard ⚠️ Important Considerations

Deploying Node Unblocker on Vercel is a classic "it works until it doesn't" scenario. While the initial setup is incredibly easy and the free tier is appealing, the platform is fundamentally mismatched with the needs of a proxy server.

const unblocker = new Unblocker( prefix: '/proxy/', requestMiddleware: [ (req, res, next) => // Optional: restrict to allowed sites next();

// /api/proxy.js (Vercel Serverless Function)
export default async function handler(req, res) 
  const target = req.query.url;
  if (!target) return res.status(400).send('Missing url');
  try 
    const url = new URL(target);
    // Whitelist/validate scheme and host if needed
    if (!['http:', 'https:'].includes(url.protocol)) return res.status(400).send('Invalid scheme');
    // Simple auth: require an API key header (implement robust auth in production)
    const apiKey = req.headers['x-api-key'];
    if (apiKey !== process.env.PROXY_API_KEY) return res.status(401).send('Unauthorized');
