Redoc Theme for gRPC UI

Prerequisites

Go >= 1.17

Install

go get github.com/nhatthm/grpcui-redoc

Usage

Use grpcuiredoc.HandlerViaReflection() or grpcuiredoc.Handler() the same way as fullstorydev/grpcui.

For example:

package exmaple

import (
	"fmt"
	"net/http"
	"os"
	"path/filepath"

	grpcuiredoc "github.com/nhatthm/grpcui-redoc"
	"google.golang.org/grpc"
	"google.golang.org/grpc/reflection"
)

func main() {
	// ----------------------------
	// Start up our gRPC server
	// ----------------------------
	svr := grpc.NewServer()

	// we need the reflection service, to power the UI
	reflection.Register(svr)

	// ...
	// register our gRPC services and then start up the server in a goroutine
	// ...

	// ----------------------------
	// Create a client to local server
	// ----------------------------
	cc, err := grpc.Dial(fmt.Sprintf("127.0.0.1:%d", grpcPort))
	if err != nil {
		panic(fmt.Errorf("failed to create client to local server: %w", err))
	}

	// ----------------------------
	// Create gRPCui handler
	// ----------------------------
	target := fmt.Sprintf("%s:%d", filepath.Base(os.Args[0]), grpcPort)
	// This one line of code is all that is needed to create the UI handler!
	h, err := grpcuiredoc.HandlerViaReflection(ctx, cc, target)
	if err != nil {
		panic(fmt.Errorf("failed to create client to local server: %w", err))
	}

	// ----------------------------
	// Now wire it up to an HTTP server
	// ----------------------------
	serveMux := http.NewServeMux()

	serveMux.Handle("/grpcui/", http.StripPrefix("/grpcui", h))
}
