In this hands-on course, you will build your own HTTP tunneling application from scratch using Node.js, WebSockets, PostgreSQL, and React. Instead of simply using tunneling tools, you will learn how they work internally by implementing a complete production-grade tunneling system step by step. This course focuses on real-world system architecture, giving you practical experience building a developer infrastructure tool similar to ngrok.
What You Will Build
During the course, you will design and implement a complete three-component system:
- Tunnel Agent (CLI Application): A Node.js command-line tool that runs locally on a developer’s machine and creates a secure tunnel connection to the internet.
- Tunnel Server (Relay Server): A Node.js server responsible for managing tunnel connections, receiving public traffic, and routing HTTP requests to the connected agent.
- Real-Time Monitoring Dashboard: A React application that visualizes tunnel connections and request activity in real time.
By the End of the Course
You will have built a fully functional HTTP tunneling platform, including:
- a Node.js CLI tunnel agent
- a tunnel relay server
- a React real-time monitoring dashboard
You will also gain practical experience designing networked backend systems and developer infrastructure tools that can be showcased in your portfolio or extended into a real product.
