Tunnel

An attempt to build a clone of Ngrok. While it may be a bit buggy, it works and demonstrates the basic functionality of tunneling HTTP requests.

---

Features

• gRPC Bi-Directional Streams: Enables seamless communication between the client and server.
• Subdomain Mapping: Access your HTTP server on a custom subdomain like subdomain.localhost:8080.
• Work in Progress: The code is a mess.

---

Prerequisites

Ensure you have the following installed:

• Go
• Make
• Protocol Buffers Compiler (protoc)

Building

1. Generate gRPC structures:

   make proto

2. Install dependencies

   go mod tidy

3. Build the binaries:

   make build

Running

1. Start the server:

   ./bin/server

2. Start the client with the desired port and subdomain:

   ./bin/client <port> <subdomain>

   Example:

   ./bin/client 3000 mysubdomain

3. Access your HTTP server on:

   mysubdomain.localhost:8080

How It Works

• The client and server communicate using gRPC Bi-Directional streams, facilitating real-time tunneling of requests.
