Problems with npm install
First of all, I found this project through Hackady, and I think it's really great! Thank you!
I tried to add a library (newtype-ts, as described in PR #31), but running npm install newtype-ts
scrambles all my local node-modules
libraries.
I think there should be a better / more robust way for adding, changing, or upgrading npm modules.
Yes, there certainly should; the way this project is laid out currently fights npm and requires significant manual rejiggering of the node_modules
folder. At some point, I'm hoping to come back and refactor it to use entirely es5 modules and proper typescript (rather than global-namespace embeds and vanilla js). This is going to need significant work to bring some of the dependencies in-line, so I don't currently have an estimate for when that's going to come about...
(Thank you for the PR, by the way!)
I need to learn how to set up webpack for a different project. If it's all right with you, I could try and set up CascadeStudio to be bundled with Webpack, perhaps with Babel for TS support. I don't really know how to do it yet, but I'd love to give this a go.
I was thinking about teaching myself the same thing a month ago, but that was when I learned that webpack is an absolute monstrosity, and probably the root of a lot of evil in modern web tech. You can see the half-baked carnage from such experimentation here in feat-modules
.
Once the trauma from that has worn off, my eventual hope is to come back and try Snowpack, which markets itself as a more humane webpack (that can also automatically convert pre-esm modules into esm modules!). Since several of the dependencies in CascadeStudio predate ECMAScript5 modules, this functionality could be a huge time-saver...
Cool, I didn't know about Snowpack. If it's ok with you, I could give this a go.
Fine with me 👍
I'd recommend starting from either #15 or feat-modules
(since they have my WIP typescript support integrated).
I started working on #15, by separating the service worker importScripts
from the node_modules and post-processing opencascade.wasm.js
to exclude export default opencascade;
. I did that since they are not module imports, and will not be detcted by Snowpack, if I understand correctly.
You can find it in my cloned repo on the separate-nod_modules branch.
I included a npm script in package.json
called 'prep' to clone OpenCascade and opentype.js (which I also added to package.json
). I cloned TS manually since I believe there's a compilation step, which I did not do.
When I run it locally with the node_modules from the cloned repository it runs OK, but when I try to install all dependencies from npm and then running my pre-processing script npm run prep
, I get errors regarding missing functions. I could not trace the origin of the problem, but I assume that you've done some more editions to opencascade.wasm.js
which I caould not easily track. Maybe a different OC build?
I hope I'm on the right track, and hope you can help me trace the bugs. Here are the error logs from Chrome's console:

If you're trying to do a fresh npm install
, you may be grabbing the embind version of opencascade.js
(which is now the default in that repo, but not in CascadeStudio), which adds and renames nearly all of the functions.
I have a mostly working embind port here: https://github.com/zalo/CascadeStudio/pull/12
You'll notice I also patch out some lines (and patch in some debug/error reporting functionality).
