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.

Line Printer Daemon

This project implements Berkeley style line printer daemon in Javascript.

License

MIT

Installation

npm install -g lp-daemon

This will install lp-daemon globally. As an option you might wish to install it locally in a project as that project's dependency:

npm install lp-daemon

The project is exposing a function creating the server instance for its programmatic control.

Usage

On a global installation the following command is available:

lp-daemon --null

This command will start lp daemon with a backend dumping incoming requests to console, only.

lp-daemon --ipp=http://1.2.3.4:631/printers/%s

This time lp daemon is started with a backend forwarding print jobs to an IPP service at provided URL. In that URL occurrences of %s are replaced with queue name as given in a print job.

Running as a Service

This daemon is designed to run in foreground. Use software like systemd, forever or pm2 If you like to run it in background permanently.

Security Considerations

In Linux this software must be run as root, currently, for listening on port 515 as required. There are some countermeasures to this increased exposure to security vulnerabilities. Running the service in a docker container might limit the effects of a successful attack.
