Grpc and protobuf


i am new to n8n. I had searched but can’t find grpc but only http. Can i check is it possible to custom make one?

other than json, is it possible to have protobuf format? thanks

Have you tried to include as npm libraries when running n8n inside docker?

You can use them from a Function or Function Item node.

Check the libraries


Thank you very much. I didn’t know that. Thanks for sharing.

You are welcome!


Glad I found this thread. But I’m less-developer, more project manager. I found this post about including libraries in Docker, but could someone help me with an terminal command that I’d need to run to include these two libraries. I need to use grpc services to automate some ridiculous work I often do…

This is my ‘normal’ Docker command:
docker run -it --rm --name n8n -p 5678:5678 -v ~/.n8n:/home/node/.n8n -v ~/Downloads:/mnt/Downloads n8nio/n8n

Thanks in advance.
