How to convert a .sb3 to .html in the command line?

I have a repo with scratch files (sb3) and I’d love to have my pipeline convert them to html and host them via github/gitlab pages.

Can I use this repo to do that? Is there some documentation?

I’m looking for something like

npm convert --to-html file.sb3 --output public/file.html

Here’s a more complete fixed version with Packager vs packager also fixed

const fs = require('fs')
const path = require('path')
const Packager = require('@turbowarp/packager')

const run = async () => {
  const projectFile = process.argv[2];
  console.log("Project File: "+projectFile);
  const projectData = fs.readFileSync(projectFile);
  const progressCallback = () => {};
  const loadedProject = await Packager.loadProject(projectData, progressCallback);

  const packager = new Packager.Packager();
  packager.project = loadedProject;

  const result = await packager.package();
  fs.writeFileSync(path.join(__dirname, 'demo_output.html'), result.data);
};

run()
  .catch((err) => {
    console.error(err);
    process.exit(1);
  });

you should do this instead:

  const projectData = fs.readFileSync(projectFile);
  const progressCallback = () => {};
  const loadedProject = await packager.loadProject(projectData, progressCallback);

loadProject has a second argument that’s a function it’ll call with progress information. It’s supposed to be optional but apparently that was broken at some point
