I have developed a script module. This script can only be executed on the gatway because it involves some files on the server. Now I want to call this script on the client. What should I do

You will need to use the RPC (remote procedure call) infrastructure of Ignition. There’s an example in the SDK that shows the basics.

In my Orekit module, I stream/cache files between the gateway and clients using web requests.

Gateway:

Client:

Are you implementing any security? Ignition's RPC infrastructure only works through authenticated channels--you only have to check roles, and only if applicable.

Nothing meaningful at this point. The accessible directories are limited but there’s no user authentication. I chose web requests instead of RPC in order to share the files with non-Ignition clients.
