• Fix testing on windows

Install

npm install @zodern/nodemiral

Features

• Support connecting to any unix remote server
• Authenticate with password(using sshpass) or with a pem file
• Can work with multiple servers at once
• Supports, copy, execute and executeScript at core methods
• Familiar NodeJS API

Example

var nodemiral = require('@zodern/nodemiral');
var session = nodemiral.session('hostname', {username: 'root', password: 'password'});

session.execute('uname -a', function(err, code, logs) {
  console.log(logs.stdout);
});

API

Session

Create a session to a remote server. You can invoke following methods after created a session

@param hostname - hostname or ip addess
@param auth - object containing following fields: `username` and (`password` or `pem`)
@param options - object of options described below
nodemiral.session(hostname, auth, options);

options:

• ejs - ejs options with ejs fields
• ssh - object whose key and value will be passed as -o key:value to any ssh session. For example { 'StrictHostKeyChecking': 'no', 'UserKnownHostsFile': '/dev/null' }

Session Methods

execute

execute given shell command on the remote server

@param shellCommand - shellCommand
@param options - {onStdout, onStderr}
@param callback - callback containing following parameters
  err - err if exists
  code - status code of the ssh process
  logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
session.execute(shellCommand, callback);

executeScript

execute a local shell script in the remote server. You can template shell script with EJS.

@param localScriptFile - localScriptFile
@param options.vars - variables to the template if uses ejs in the script
@param callback - callback containing following parameters
  err - err if exists
  code - status code of the ssh process
  logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
session.executeScript(localScriptFile, options, callback);

copy

copy a file from local machine to the remote machine. Supports binary files too. Support EJS templating with non-binary files

@param localFile - localFile
@param remoteFileLocation - remoteFileLocation
@param options.vars - templateVars
@param optiosn.progressBar - show progress bar
@param callback - callback containing following parameters
  err - err if exists
  code - status code of the ssh process
  logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
session.copy(localFile, remoteFileLocation, options, callback)
