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 🙏

Dev Certificates

Easy creation of local trusted SSL certificates for developers.

Quickstart

npx @squaredle/local-ssl-certs issue --name Acme dev-certs acme.test "*.acme.test"

Usage

  1. Run:

    npx @squaredle/local-ssl-certs issue --name Acme dev-certs acme.test

  2. Install the resulting CA certificates:

    • The root CA certificate (ending in .crt) must be installed in your Trusted Root Certification Authorities store.

      • By default, the root CA's private key is deleted after creation so it can't be used against you.

    • The intermediate CA (also ending in .crt) must be installed in your Intermediate Certification Authorities store.

      • This certificate can only be used to sign certificates for .test domain names, so it's relatively safe to keep the private key around.
      • Alternatively, you may delete the intermediate private key, but you'll need to reissue and reinstall the root and intermediate CA certificates to generate new certificates later.

    • Installation varies by OS:

      • Windows: Open the root and intermediate .crt files and install each in its appropriate store (see above).

      • Mac: Open the root and intermidate .crt files in Keychain Access and install them in the System keychain, set to "Always Trust".

      • Linux: Varies by distribution. For Ubuntu:

        sudo cp dev-certs/root-ca.crt /usr/local/share/ca-certificates/
sudo update-ca-certificates

  3. Configure your local web server to use the generated certificate and key:

    • For example, if you're using http-server:

      npx http-server -S -C dev-certs/your-local-domain.test.crt -K dev-certs/your-local-domain.test.key

    • Or in an Apache VirtualHost:

      SSLEngine on
SSLCertificateFile /path/to/dev-certs/your-local-domain.test.crt
SSLCertificateKeyFile /path/to/dev-certs/your-local-domain.test.key

  4. Test the SSL certificate:

    • You may need to restart your browser or device for new CAs to take effect.
    • Open your browser and navigate to https://your-local-domain.test.
    • If everything is set up correctly, you should see a secure connection without any warnings.
