Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

#aux

To simplify scripting access to multiple machines, we present here a simple API that makes running commands on a POSIX compliant system, either local or remote, nothing short of a breeze.

Remote commands are run via ssh, and the aux binary can work as a proxy script, that enables an administrator to granulate access control.

##Install

###Server

On the machine you wish to control, you will probably want to use aux as a proxy script. This allows you to restrict client access to only pre specified commands. In this case you should just run:

npm install -g aux

###Client project

When using the aux library to control some machines from your application, just install as a dependency:

npm install aux

##Usage

###Server

aux --user <username> --add-key <pub_key>
aux --user <username> --remove-key
aux [--user <username>] --add-command <command>
aux [--user <username>] --remove-command <command>

###Client project

var aux = require('aux');

aux.testing = new aux.Remote({host: 'testing.example.com'});
aux.staging = new aux.Remote(
  {host: 'staging1.example.com'},
  {host: 'staging2.example.com'},
  {host: 'staging3.example.com'});

// optional callback with args: ({Error}, {Array})
aux.local('command', callback); 
aux.testing('command1', 'command2');
// if callback is provided, it is called when all servers have responded, with
// args: ({Error}, {Array})
aux.staging('command', callback); 

##Usage example

As a contrived example, say we want enable the happy user, Fred, restart nginx on our Ubuntu server

  1. First we add Fred's public authentication key to our server
aux --user fred --add-key "ssh-rsa AAAA...=="
  1. Next we allow Fred to restart any service on the system
aux --user fred --add-command "sudo service \w+ restart"
  1. Create a simple script for Fred to use on his machine
var aux = require('aux');

aux.server = new aux.Remote({host: 'example.xom'});
aux.server('sudo service nginx restart', function (err, result) {
  if (err) throw err;
  console.log(result.join('\n\n'));
});

Now Fred can simply call this script to restart nginx on the server.

node restart_nginx.js
