creating threads with Processing.js ?

in Processing with Other Languages • 2 years ago

hi !

I'm working on a sketch in processing.js, where data are dynamicaly loaded (every seconds ) from a text file on the server through the loadString function. But, everytime I load the textfile, my sketch is slowed down by the process. Is there a way to create a threads to run this process in processing.js or javascript ? Or maybe another solution to handle this problem ?

This belongs to Processing Implementations (sigh). Moved.
And no, you cannot do that, JavaScript is a mono-threaded language...

Actually, there is. They are called Web Workers and are a fairly new invention, so understand they are not widely supported.

Sorry to come in late, did you think of loading your data with AJAX (XMLHttpRequest)? That should give control back to your drawing

Thanks for your responses !

Three months ago, when I came with this problem, I finally discovered the existence of web workers, but I was unable to use it with processing.js. Oh, and no, I didn't think to use XMLHttpRequest, but it could be useful in the future !
