go-openrpc-reflect

Use reflection to generate OpenRPC service descriptions from static code and at runtime.

GoDoc

Design

Go's net/rpc service works by using a code-style convention to structure a reflection-based implementation to build RPC servers around business logic.

This package works in a similar way, but instead of building RPC servers, it builds service descriptions (of those servers) which meet the OpenRPC Specification. Differentially, this package doesn't strictly enforce any specific code-style conventions, but provides an extensible pattern that can be moulded to fit nearly any RPC service implementation, whether hand-rolled or conventional. Sane defaults are provided fitting the conventions of popular Go RPC libraries, namely net/rpc and ethereum/go-ethereum/rpc.

this project is intended to open the door to openrpc adoption — and service discovery patterns in general — by removing the hurdle of requiring a human to actually sit down and write (and maintain) a complete and correct description of potentially complex services.

It enables APIs to provide accurate, complete, and dynamic descriptions of themselves which can adapt to varying permissions and visibility scopes, server businesses, and transport contexts.

Default Configurations

Two default Reflector configurations are included:

  • StandardReflector is intended to pair well with net/rpc,
  • EthereumReflector pairs with github.com/ethereum/go-ethereum/rpc.

These implementations can be customized to a large degree, or can be used as references to build your own from scratch. The EthereumReflector is basically a customized version of the StandardReflector.

StandardReflector

The StandardReflector expects your API to be built following the pattern supported by Go's net/rpc library, which looks like this:

func (t *T) MethodName(argType T1, replyType *T2) error
EthereumReflector

The EthereumReflector expects your API to be built following the pattern supported by the Ethereum Foundation's github.com/ethereum/go-ethereum/rpc package, which looks like this:

func (s *CalcService) Add(a, b int) (int, error)

Library Limitations

  • Parameter and result type discovery only works for exported fields. If your API uses types that don't expose fields that you want to be documented, you'll need to use a custom schema definition.
  • Custom encoding/marshaling. If your API or types use custom encoding (eg. type json.[Un|]Marshal methods), you may need to use custom schema definitions as above.
  • As of Go 1.13, Go provides a go build flag -trimpath, which removes all file system paths from the compiled executable, to improve build reproducibility (and reduce artifact sizes). Stripping file paths from their absolute context at build time prevents the AST parsing steps in the library from knowing where to look. This may be addressed in later versions of this library.

Short Example

// Follow the standard Go RPC service establishment pattern.
calculatorRPCService := new(MyCalculator)
server := rpc.NewServer()
// Register the receiver to the net/rpc server.
err = server.Register(calculatorRPCService)
if err != nil {
    log.Fatal(err)
}

// Instantiate our document with sane defaults.
doc := &go_openrpc_reflect.Document{}
// Set up some minimum-viable application-specific information.
doc.WithMeta(&go_openrpc_reflect.MetaT{
    GetServersFn: func() func(listeners []net.Listener) (*meta_schema.Servers, error) {
        return func([]net.Listener) (*meta_schema.Servers, error) { return nil, nil }
    },
    GetInfoFn: func() (info *meta_schema.InfoObject) {
        return nil
    },
    GetExternalDocsFn: func() (exdocs *meta_schema.ExternalDocumentationObject) {
        return nil
    },
})
// Use a provided default Standard reflector pattern.
doc.WithReflector(go_openrpc_reflect.StandardReflector)

// Register the receiver to the doc.
doc.RegisterReceiver(calculatorRPCService)

// Wrap the document in a very simple default 'RPC' service struct, which provides one method: Discover,
// which returns the doc.Discover() value.
rpcDiscoverService := &RPC{doc}

// Register the OpenRPC Document service back to the rpc.Server.
err = server.Register(rpcDiscoverService)
if err != nil {
    log.Fatal(err)
}

// net/rpc is sort of funny because it has these special conventions that you have

// These are conventions such as:

// - arguments must each be pointers
// - ... etc.
// Because these conventions are kind of funny, people often just use wrappers that fit
// these conventions around their 'actual' methods.
// But for the sake of brevity, which I'm probably close to losing anyways, we're just
// going go for the bone.
