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.

AWS Lambda Layer Pack

aws-layer-pack -- a tool for creating AWS Layers

A CLI tool for packaging project dependencies into a zip that can be deployed as a Layer on AWS Lambda.

About

AWS Lambda now allows for common code to be packaged and deployed as layers. This not only allows code to be shared between multiple Lambda functions, but also provides a way to write and test code in Lambda without having to publish dependencies with every change.

The aws-layer-pack is a command line tool that makes creating the file used for AWS Layer deployment easy for nodejs projects. The tool packages all of the production dependencies listed in the projects package.json into a properly formatted zip that can then be uploaded to AWS Lambda.

Installing

npm i -g aws-layer-pack

Creating AWS Layer package

Run aws-layer-pack on the command line at the root of a node project.
Upload the created layer.zip file to AWS as a Layer.

IMPORTANT

npm must be on the path for this tool to work properly.
