Are Node addons supported / will CEP ever support them?

[undavide]

Hi, according to this thread in the Forums, Node addons are not supported. But apparently they're used in an Adobe sample extension, so it's really unclear whether they work even if they shouldn't, or what else.

I'm doing tests with them and I keep getting "Uncaught Error: Module did not self-register." Since I'm just hacking node addons, I'd like to understand if it's just me doing something wrong, or CEP itself that can't support them. In which case... will it ever support them or it's a completely locked option?

Thank you! –Davide

As a side note, the Node.js that powers Photoshop Generator seems to digest addons pretty well!

@undavide This would make a great topic for a blog post!

Javascript Node.js addons are supported. However, native Node.js addons are not officially supported (you might need to rebuild the add-on using CEP's version of libuv and v8).

Thanks @dinghui0712 ! I've compiled a native add-on (this one: https://github.com/EyalAr/lwip) following the instruction in its own repository. Can you please point me to doc about recompiling the sourcecode using "CEP's version of libuv and v8" (I'm afraid I'm only hacking that lwip library and I have no clue about libuv and v8) Thank you very much!

Having trouble using a .node binary and hoping others might have figured this out in the better part of a decade since this was reported… :sweat_smile: The original linked forum thread seems to be gone—has the URL moved?

Yes, this would be very helpful indeed! Or a reference to where you were told this, so we can follow up.

Where/which?

Indeed. Fortunately I was able to de-archive it: https://community.adobe.com/t5/exchange-discussions/are-node-js-addons-supported-by-cep/td-p/6872845

Oh in that specific thread, the destination sample has also moved, this one is for CEP 10 & 11: https://github.com/Adobe-CEP/CEP-Resources/tree/master/CEP_11.x/Samples/CEP_HTML_Test_Extension-10.0/node_modules/mongodb/node_modules/bson

Thanks! I had replied to another discussion, but a community expert deleted my reply and shamed me for bringing the discussion back for some reason..

Anyways, another thread suggested using WebAssembly/WASM to get around the limitations, but I'm not really sure if that covers the same bases or how involved that might be: https://community.adobe.com/t5/indesign-discussions/c-node-addons-supported-in-cep/m-p/14044844#M539960

@heyakyra - I don't fully understand what you're trying to do, and what is blocking you. People use node all the time in CEP extensions, and sometimes it causes problems, but it's not prohibited... When you say "node binary" do you mean there's a C++ component?

[heyakyra]

Yes, exactly. Sorry I guess that context was only in the link
