Create a new directory on your local machine and initialize a Node.js project.
const app = express(); const unblocker = new Unblocker( prefix: '/proxy/' );
Vercel Hobby accounts enforce a maximum execution timeout of 10 seconds (up to 60 seconds on Pro plans) for serverless functions. If you attempt to stream large files, download videos, or load heavily asset-loaded websites through the proxy, the function will hit this limit and terminate prematurely, resulting in a FUNCTION_INVOCATION_TIMEOUT error. No WebSocket Support
Deploying Node Unblocker on Vercel allows you to create a personal proxy utilizing Vercel's global edge network. This guide covers how to set up, configure, and optimize Node Unblocker for Vercel's serverless architecture. Understanding the Compatibility Challenge node unblocker vercel
Leave the build settings as default. Vercel automatically detects the Node.js environment and deploys the api folder. Overcoming Edge Cases and Limitations
: Your proxy is deployed across Vercel’s global network, reducing latency by routing traffic through the server closest to you.
: Vercel’s Hobby plan has a 10-second execution limit for functions. If a site takes longer to load through the proxy, the request will fail. Create a new directory on your local machine
Vercel’s AUP explicitly prohibits the operation of "proxy servers" or "anonymizers" on their platform without express permission.
Alternatively, if you placed your code in api/index.js , Vercel will automatically treat it as a serverless function.
Deployments can be triggered automatically via GitHub integration. Step 1: Understanding Serverless Limitations No WebSocket Support Deploying Node Unblocker on Vercel
Vercel’s infrastructure is distributed worldwide, meaning the proxy often benefits from low-latency connections.
