About

HiveSsh simplifies SSH2 connections via promise-based task execution on Linux servers with built-in server utilities and powerful command execution functions.

HiveSsh is a library designed to streamline SSH2 connections and task execution on Linux servers. It provides user-friendly promise-based functions for efficient server operations without the need for a client application.

Beta info

This software is yet not fully developed and will change over time. If a version is intended to be used in another release, it is recommended to pin the dependency to a version to prevent beta breaking changes.

Feel free to test the software and submit suggestions for improvements or problems.

Key Features

HiveSsh offers the following key features:

• All-Distributions: SSH2 and SFTP operations for all Linux servers

• Promisified: Promise-based functions for ease of use

• AbstractPackageManager: Built-in abstract package manager with support for apt, dnf, and yum, with additional configurability

• Exec: Command execution utilities for event or promise-based error handling and output parsing, filtering, and mapping

Requirements

HiveSsh requires the following server environments:

• SSH2 server
• SFTP support
• Linux distribution

Getting started

npm i hivessh

import { SshHost } from "hivelib"
// or import SshHost from "hivelib" (SshHost is also the default export)

//connect
const myHost = await SshHost.connect({
    host: "127.0.0.1",
    //port: 22, (default 22)
    //user: "root", (default root)

    //password: "123456789",
    // or
    //privateKey: "..."
    // or
    //privateKeyPath:"/home/user/.ssh/id_rsa",
    //passphrase: "123456789"
})

Here are some using examples:

Promisified

Execute and assets

After connecting an SshHost, you can use the promisified execution (and other asset features) directly on the SshHost instance.

// check files in user home dir
const homeDirFiles = await myHost.exec("ls -al")
console.log("Home dir files:\n", homeDirFiles.out)

Get the hosts public ip address:

// check if curl command exists
const curlExists = await myHost.exists("curl ifconfig.me")
if(!curlExists){
  myHost.close()
  throw new Error("Curl is not installed on: " + myHost.settings.id)
}

const myIp = await myHost.exec("curl ifconfig.me")
console.log("Host public ip: " + myIp.out)
//other sources: `api.ipify.org`, `ipinfo.io/ip` or `ipecho.net/plain`

You can also execute commands on absolut path:

const homeDirFiles = await myHost.exec(
  "ls -al",
  { pwd: "/etc" }
)
console.log("Etc files: ", homeDirFiles.out)

Also a git example:

// check if git command exists
const gitExist = await myHost.exists("git")
if(!curlExists){
  myHost.close()
  throw new Error("Git is not installed on: " + myHost.settings.id)
}

// get git status
const gitStatus = await myHost.exec(
  "git status",
  {
    pwd: "/home/tester/myrepo"
  }
)

console.log("Git status:\n", gitStatus.out)

Sftp

You can also use the promisified SFTP features via SshHost.sftp.

const myBinary: Buffer = await myHost.sftp.readFile("/home/tester/my-binary")

const exampleConfig: string = await myHost.sftp.readFile("/etc/example/config.yml", "utf8")

AbstractPackageManager

With the abstract package manager (apm) you can use apt, dnf, yum or a custom implemented package manager via one interface. The apm features are limited and general, but you can update your system and install, delete and list your packages.

// upgrade all packages using the abstract package manager
const apm = await myHost.getApm()
await apm.updateCache()
await apm.upgradeAll()

// install a package using the abstract package manager
await apm.install("git")
