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

@bitbybit-dev/jscad

JSCAD solid modeling integration for Bitbybit - programmatic CSG operations, extrusions, hulls, and more for creating precise 3D geometry through code.

Overview

This package wraps the OpenJSCAD kernel with additional algorithms from Bitbybit. JSCAD excels at programmatic solid modeling using constructive solid geometry (CSG) - perfect for parametric designs, mechanical parts, and 3D-printable models.

Works in both Node.js and browser environments. For browser apps, we recommend @bitbybit-dev/jscad-worker which wraps this library in a non-blocking WebWorker.

Quick Start

The fastest way to scaffold a project with JSCAD pre-configured:

npx @bitbybit-dev/create-app my-project --engine threejs
cd my-project
npm install
npm run dev

This creates a complete Vite + TypeScript project with JSCAD, OCCT, and Manifold kernels ready to use. Learn more about the CLI.

Need Server-Side CAD?

The CLI first asks you to choose between a Frontend app or a CAD Cloud app. Select "cloud" to scaffold a full-stack project with a backend (Hono on Cloudflare Workers, Node.js Express, or ASP.NET Core) and a React + Three.js frontend. Your API key stays on the server and the frontend proxies requests through your backend:

npx @bitbybit-dev/create-app my-cloud-project --type cloud

Choose from 5 backend templates: Hono + SDK, Hono + REST, Node.js + SDK, Node.js + REST, or .NET + REST. Each includes ready-to-run examples with model generation, batch operations, and CAD pipelines. Learn more.
