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 🙏

Readme

TypeScript Numeric Type Patcher

Patches built-in TypeScript declarations to use stricter numeric types in DataView and TypedArray sub-classes.

Read more about it in this blog post: https://tobloef.com/blog/stricter-typescript-numerics.

To run it, simply enter the root folder of your project (the one containing the node_modules folder) and run:

npx typescript-numeric-type-patch

You can optionally specify the path of your project manually:

npx typescript-numeric-type-patch ./path/to/project

By default, the patcher will use "loosely" branded types (number is assignable to Int32). If you want to use "stricly" branded types (number has to be cast to Int32), you can use the --strict flag:

npx typescript-numeric-type-patch --strict

If you don't want to run this manually every time you install TypeScript in your project, you can generate patch files with patch-package for Node.js or bun patch for Bun.
