Any idea to modify recrypt function as a promise based one? currently It's blocking the event loop!

[rvigneshw]

When trying to use recrypt function to encrypt a pdf on server, no other request is getting processed

can you try to use this: https://github.com/julianhille/MuhammaraJS/issues/92#issuecomment-871671379

this works with streams but im unsure if this unblocks the event loop

[rvigneshw]

Tried that, but still, my event loop is blocking :-[

I'll have a look at it.

[julianhille]

i digged a bit deeper and the blocking is not from js itself. The cpp code of PDFDocumentCopyingContext and then WriteNewObjects and a foor loop. I don't think this is possible to rewrite as promise without a major rewrite of the underlying cpp code.

Maybe worker threads or multi processing will solve your problem

[julianhille]

Can you give me a small sample snippet to reproduce? An oddly huge pdf i could find myself. 😂

[julianhille]

Update: i've got some idea and will try that.

Any solution about this? Which recrypt will block the whole nestjs backend

@zhuxb711 do you have any updates on this

@xLEpEX Use "Threadz" to run it on another thread
