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 🙏

next-typesafe-url

Now with full support for app directory and server components!

Fully typesafe, JSON serializable, and zod validated URL search params, dynamic route params, and routing for NextJS.

Big shoutout to tanstack/router and yesmeck/remix-routes for inspiration and ideas.

Whats wrong with curent solutions?

Routing

Next.js's non-typesafe routing can lead to runtime errors and make it difficult to catch routing-related issues during development, as it relies on string literals instead of type-safe constructs.

Search Params

from tanstack/router:

Traditional Search Param APIs usually assume a few things:

  • Search params are always strings
  • They are mostly flat
  • Serializing and deserializing using URLSearchParams is good enough (Spoiler alert: it's not, it sucks)

Typesafety Isn’t Optional

How does next-typesafe-url solve these problems?

  • Fully typesafe routing- all the way from the route, to the route params, to the search params
  • Search params are JSON-first, so you can pass strings, numbers, booleans, nulls, and even nested objects and arrays
  • Search and route params are validated at runtime using zod, so you can be sure that the data you get matches the schema you expect
