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

smart-type-expander

A lightweight, zero-dependency CLI tool built on top of the native TypeScript Compiler API. It recursively expands deeply nested, truncated TypeScript types into fully structural representations while safely protecting native objects, class instances, and ORM schemas from breaking into internal prototype definitions.

Features

  • Deep Recursive Expansion: Breaks open nested object shapes, intersections, and unions.
  • Smart Auto-Detection: Automatically shields native globals (Date, RegExp, Promise, Map, Set), third-party class instances (Decimal, BigNumber), and database schemas (Zod, Prisma $Enums) from expanding into raw internal prototypes.
  • Prettier-Style Formatting: Auto-aligns brackets and outputs clean, 2-space indented definitions row-by-row.
  • Config Inheritance: Dynamically locates and reads your project's nearest tsconfig.json to accurately resolve absolute paths, baseUrl, and external dependencies.

Installation

You do not need to install it locally. Run it on-demand inside any repository using npx:

npx smart-type-expander <path-to-file> <type-name>
