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 🙏

Upgrading to v10

Formly v10 requires Angular 21 or newer. Upgrade Angular first, then update all @ngx-formly/* packages used by your application together to v10. The Material, PrimeNG, and NG-ZORRO integrations require version 21 or newer of their respective UI libraries. Kendo requires version 21.4.1 or newer, and NativeScript requires @nativescript/angular 21 or newer. Applications staying on Angular 20 should use Formly v9.

See the v10 upgrade guide for migration steps.

Upgrading to v9

Formly v9 requires Angular 20 or newer. Upgrade Angular first, then update all @ngx-formly/* packages used by your application together to v9. The Material, PrimeNG, and NG-ZORRO integrations require version 20 or newer of their respective UI libraries. Kendo requires version 19.1 or newer, and NativeScript requires @nativescript/angular 20 or newer. Applications staying on Angular 19 should use Formly v8; applications staying on Angular 18 should use Formly v7.

PrimeNG datepicker fields no longer accept monthNavigator, yearNavigator, or yearRange, which PrimeNG 20 removed. Replace @primeng/themes imports with @primeuix/themes when configuring a PrimeNG theme.

See the v9 upgrade guide for migration steps and the changelog for the full list of changes.
