Holesail is a truly peer-to-peer network tunneling and reverse proxy software that supports both TCP and UDP protocols.

Holesail lets you share any locally running application on a specific port with third parties securely and with a single command. No static IP or port forwarding required.

Before using Holesail, make sure you have Node.js installed on your system. You can download Node.js from the official website: https://nodejs.org/en/download/

Once Node.js is installed, you can install Holesail Server using npm (Node Package Manager):

npm i holesail -g

To start a local Holesail Server, use the following command:

holesail --live <port>

Replace port with the desired port number you want to expose to the network.

This will give you a connection string to connect to, use that to access this server from anywhere:

holesail <connection-string>

To view full usage instructions and all set of commands, run:

holesail --help

const Holesail = require('holesail')

const hs = new Holesail({
  server: true, // act as a server
  secure: true // use secure mode
})

await hs.ready()

console.log('Server is ready:', hs.info.url)

Or as a client:

const Holesail = require('holesail')

const hs = new Holesail({
  client: true,
  key: 'hs://s000abcdef...' // URL or raw key
})

await hs.ready()

console.log('Client connected:', hs.info)

API

new Holesail(opts)

Options:

• server Boolean Start as server (default false)
• client Boolean Start as client (default false)
• key String Optional. URL or raw key for connecting
• secure Boolean Enable secure mode (default false)
• port Number Optional. Specific port to bind/connect
• host String Optional. Specific host to bind/connect
• udp Boolean Optional. Force UDP usage (advanced)

.ready() Wait for Holesail to initialize and connect.

.pause()

.resume()

.info() Get metadata about the current Holesail instance:

.close() Gracefully shuts down the connection and releases resources.

Holesail uses a simple URL format for sharing server locations:

• Secure server: hs://s000

• Insecure server: hs://0000

The parser will auto-detect and split the prefix for you. If you pass a full hs:// URL to the constructor, it'll Just Work
