rhino3dm.js incompatible with Node v18. I keep getting error ERR_INVALID_URL

[dgrcode]

I was getting this issue with 0.14.0. After upgrading to 7.15.0 I keep getting the same error.

TypeError: Failed to parse URL from {project path}/node_modules/rhino3dm/rhino3dm.wasm
    at Object.fetch (node:internal/deps/undici/undici:11118:11)

    input: '{project path}/node_modules/rhino3dm/rhino3dm.wasm',

  }
}

I'm not sure what's going on, because the file at {project path}/node_modules/rhino3dm/rhino3dm.wasm is there. I can do cat {project path}/node_modules/rhino3dm/rhino3dm.wasm and see a bunch of binary output.

I think I might have updated node to v18.12.1 before I started seeing this issue. Could this be a node 18 compatibility issue?

I do get this warning when starting the server:

(node:71881) ExperimentalWarning: The Fetch API is an experimental feature. This feature could change at any time

[dgrcode]

I can confirm I don't get this issue with node v16.19.0. We'd have to confirm this is a node 18 incompatibility issue. This would be a problem given node releases.

From node's release schedule (link), here's the versions lifetime

v16 entered maintenance status about 3 months ago, on 2022-10-18. End of life will be 2023-09-11.

What does the code that loads rhino3dm in your node server look like?

[dgrcode]

This is the code that loads rhino3dm

const rhino3dm = require('rhino3dm')

console.log('rhino3dm: initializing')
/**
 * @type Promise<rhino3dm.RhinoModule>
 */
const rhinoPromise = rhino3dm()
  .then((rhino) => {
    console.log('rhino3dm: loaded')
    return rhino
  })
  .catch((err) => {
    console.log('rhino3dm: error', err)
  })

module.exports = rhinoPromise

Then, I use it like this:

const rhinoPromise = require('./server/services/rhino3dm')

const rhino = await rhinoPromise

But I'm confident that's not the issue, because that exact code works with node v16. It has only stopped working when I updated node to v18

[dgrcode]

Hi @sbaer any news on this? Can we confirm rhino3dm.js is not compatible with Node v18?

[fraguada]

@dgrcode Depending on the version of emscriptem, web assembly compiled code is not compatible with Node v18.1.0 and above. See: emscripten-core/emscripten#16913

Seems there was a patch applied. We need to see how to build rhino3dm with an updated version of emscripten to get the benefit of the patch. emscripten-core/emscripten#16917

In the meantime you can run your scripts in node.js 18.1.0 and above like so:
node --no-experimental-fetch index.js

Running in 16.15.0 (at least, haven't checked below) - 18.0.0 works as you'd expect.

[dgrcode]

Awesome, thanks for the details and workaround 🙌

[fraguada]

update: by updating our build tools, this issue is no longer present. We are getting ready to release an update. If you want to test, you can do so my using a recent build of js: https://github.com/mcneel/rhino3dm/suites/11184627947/artifacts/571581718

[dgrcode]

I can confirm the files in the link work as expected. Thanks for fixing this one. Is there an estimate update release date?

[fraguada]

Thanks for testing!
We have most everything in place for a release except for testing. Hopefully we can wrap it up in a week or so.

@dgrcode Just published rhino3dm.js 8.0.0. https://www.npmjs.com/package/rhino3dm

[dgrcode]

Thanks for the heads up! I just upgraded to 8.0.0 and it's working great using node v18

[fraguada]

Thanks for reporting @dgrcode!

EDIT: Just opened a new issue #521 to track this

Quick question. I just created a 3dm file with the rhino3dm.js library, and it gave me an error when trying to open it with Rhino. It said something like the file had been created with Rhino 8 and it couldn't be opened with Rhino 7. I haven't seen any Rhino 8 available yet.

Is that expected?
