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 🙏

nodezoo-npm

Npm Travis Coveralls Gitter

A micro-service that provides npm data for NodeZoo. This micro-service depends on the npm registry but also caches retrieved data to reduce load on the public registry.

If you're using this microservice, and need help, you can:

Running

This micro-service can be ran as part of a complete system or as a single isolated unit.

As a complete system

A special system repository is available that runs the complete system using Docker and Fuge.

Isolated mode

To make testing easier this micro-service can be ran in 'isolated' mode. This mode allows testing over http using a well defined port. Please note isolated mode means patterns are not exposed via mesh.

To run in isolated mode,

  • Clone this repository locally,
  • Run npm install,
  • Run npm start isolated,

Note: In memory storage is used over redis in isolated mode.

A simple http service is supported and can be called using Curl or other Rest client. The default port is 8052. It can be changed using the NPM_PORT environment variable.

curl -d '{"role":"npm","cmd":"get","name":"hapi"}' http://localhost:8052/act

Configuration
