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 🙏

@ts3d-hoops/web-viewer-monolith

A self-contained version of the HOOPS Visualize Web Viewer that embeds the WebAssembly engine directly in the JavaScript bundle. This eliminates the need to serve the engine.esm.wasm file separately, making deployment simpler at the cost of a larger bundle size.

When to use this package

Use @ts3d-hoops/web-viewer-monolith instead of @ts3d-hoops/web-viewer if:

  • Your hosting environment makes it difficult to serve static .wasm files
  • You want to avoid managing the separate WebAssembly engine file
  • You prefer a single-file deployment approach
  • Bundle size is less of a concern than deployment simplicity

For most use cases, we recommend starting with @ts3d-hoops/web-viewer as it offers better performance through smaller initial bundle sizes and optimized loading.

Installation

npm install @ts3d-hoops/web-viewer-monolith

Quick Start

import '@ts3d-hoops/web-viewer-monolith';
import { WebViewer } from '@ts3d-hoops/web-viewer-monolith';

// Create a viewer instance
const viewer = new WebViewer({
  containerId: 'viewer-container',
  // Note: No need to specify enginePath with the monolith package
});

// Start the viewer
viewer.start();
<!doctype html>
<html>
  <head>
    <title>HOOPS Web Viewer</title>
  </head>
  <body>
    <div id="viewer-container" style="width: 800px; height: 600px;"></div>

    <script type="module">
      import '@ts3d-hoops/web-viewer-monolith';
      import { WebViewer } from '@ts3d-hoops/web-viewer-monolith';

      const viewer = new WebViewer({
        containerId: 'viewer-container',
      });

      viewer.start();
    </script>
  </body>
</html>

Key Differences from @ts3d-hoops/web-viewer

| Feature | @ts3d-hoops/web-viewer | @ts3d-hoops/web-viewer-monolith | | ---------------- | ---------------------------------- | ------------------------------- | | Bundle size | Smaller (engine loaded separately) | Larger (engine embedded) | | Deployment | Requires serving engine.esm.wasm | Single JS file | | Network requests | Engine loaded on demand | No additional requests | | Configuration | Must specify enginePath | No enginePath needed |

Loading Models

Once the viewer is running, you can load StreamCache models:

// Load a model from a URL
await viewer.model.loadSubtreeFromUrl({
  url: 'path/to/your/model.scs',
  modelRootIds: [],
});

// Load from server streaming
await viewer.model.loadSubtreeFromServer({
  modelName: 'your-model-name',
  modelRootIds: [],
});
