Customize or script using golang?

Hello, is it possible to customize or script on Corteza with golang (or even python)? I really dont like Javascript …

Sure. Corteza is communicating with Corredor via gRPC and you can write your own automation server in any language that can run scripts in any language.

and how to integrate them?

I have python scripts, so I created a gRPC server for them and made Corredor js triggers them
so the whole purpose of Corredor component is just to trigger python scripts

Thanks! so I can write client and server scripts/code in python and have these hosted on the corteza platform?

There is no official documentation to do this.

You can study how Corredor works and reverse-engineer it for your needs.
