PlugKit to stupidly simple, stream-capable plugin runtime for Go.
No gRPC. No protobuf. No codegen.
Just structs, CBOR, pipes and a handshake.
PlugKit is a micro-framework that lets you:
- create and run plugins as separate processes (we call them simply plugs)
- communicate with them over
stdin/stdout - pass arbitrary Go structs encoded with CBOR
- use bidirectional message routing
- gracefully terminate a plug whenever you want (
Finish)
It's like HashiCorp’s go-plugin, but:
- without the pain
- without reflection
- without type registries
- with streaming message support 😎 (in future)
PlugKit is under active development.
The API will evolve slightly, but the core already works:
- ✅ Running plugins as separate processes
- ✅ Bidirectional communication (host <-> plugin)
- ✅ CBOR serialization (
fxamacker/cbor) - ✅ Handling multiple message types
- ✅
