Has anyone done anything with Node Red and Webassemby? I am interested in trying to get Node Red working with this product but I am not sure where to start. They also have some Node.js examples but I don't know the best way to try and interface Node Red with this product. Anyone have any thoughts…

Hi @jewendt , I have last year been experimenting with Webassembly in Node-RED. At the time being it was still a bit experimental support in NodeJs. But I assume it will wirk now much better if you use a recent NodeJs version. The webassembly is some kind of Javascript bytecode that can be run fa…

[image] BartButenaers: So as soon as the onRuntimeInitialized callback function is called In fact what I mean is that your Node-RED flow might have been started, before your webassembly code has been loaded. So messages might already start arriving in your node, before you can handle them. …

Assuming you want to run this server side in Node-Red, my guess is you don't need to worry about Webassembly for this. I took a quick look at Dynamsoft's website and they have a Node.js library. (My assumption) To run it in Node-Red you probably just need to wrap the Node.js library into a custom n…

@jewendt @BartButenaers I am using webassembly with node-red mostly with QuantLib and EigenJs ( not much of a choice ) It can be extremly tricky to use Node-Red and Emscripten mostly if you want to create your wrapper for Node-Red. 1st problem : Heap allocation and request finalize for garbage co…

Hi Daniel, Thanks for the info! I haven't used wasm myself meanwhile, except for my node-red-contrib-ffmpeg-wasm . But in that node I simply use an npm module to handle all the wasm complexity for me.

Hi @BartButenaers , no problem You should give it a try when time is free, you can compile any typescript into C and vice versa For example NODE-RED -> QuickJS TSC -> C -> Emscripten -> WASM It is a pity we don't have a strict [typescript function] node to force developper to only produce typescr…

Now that I think about it , I never actually told to @knolleary , @dceejay how we can compile node-red into wasm or exe without electron. https://bellard.org/quickjs/ ( done )
