Conduit comes with a bunch of officially developed modules that should cover most of your backend's needs.
Building your own modules is entirely supported.
You can build them in any language offering support for gRPC, though we only currently provide a companion SDK for TypeScript.
Uh, oh, looks like this section is currently Under Development.
We'll do our best to document this as soon as possible.
If you need help building your own module now, shoot us a question on our Discord server.
