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.


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 🙏

AWS CDK Construct for a static site. Provides S3, CloudFront, ACM, Route53, and subdomain redirects




AWS CDK S3 Cloudfront Construct

This package provides a CDK construct that creates a Cloudfront distribution which serves content from S3 and is integrated with Route 53 and ACM. Specifically, it:

  • Creates a private S3 bucket
  • Creates a CloudFront distribution for that bucket
  • Optionally creates a Route53 record pointing to that bucket
  • Optionally creates a certificate for the distribution if a domain name is used (can use existing)
  • Optionally adds subsomain redirects, .e.g. redirects to the main
  • Optionally uploads content file to the S3 bucket and invalidates the distribution if it is already existing


The minor version of the package is synchronized to the CDK version used.


  • An aws account and relevant profile configured

Example usage

new S3CloudFront(this, 'S3CloudFront', {
  domain: {
    domainName: '', // The domain name's TLD must be an existing hosted zone in Route53
    tld: '',
  subdomainRedirects: ['www'],
  bucketName: 'examplenonadigital',
  error404Document: '404.html',


  • You need to have the correct AWS_PROFILE environment variable set as the CDK_DEFAULT_ACCOUNT and CDK_DEFAULT_REGION are picked up from the AWS_PROFILE environment variable

  • As the bucket is private and does not use S3 hosting, you need to add an edge lambda to serve index documents. The aws-cdk-standard-cloudfront-lambdas package provides these.
