Package use Grpc reflection api to download grpc proto descriptor. Now you don't have to add proto file to each package. Simple direct download proto package from example microservice without any files.

//import { GrpcReflection } from 'grpc-js-reflection-client';
import { GrpcReflection } from '../src/GrpcReflection';
import * as grpc from '@grpc/grpc-js';

/**
 * Other methods to use

try {
    (async () => {
        const c = new GrpcReflection('0.0.0.0:3000', grpc.credentials.createInsecure());

        // Find protobufjs descriptor by symbol in grpc reflection server
        const descriptor = await c.getDescriptorBySymbol('apidata');

        // Packagejs descriptor
        const descriptorMessage = descriptor.getDescriptorMessage();
        console.log(descriptorMessage);

        // Package definition
        const packageDefinition = descriptor.getPackageDefinition({
            keepCase: true,
            enums: String
        });
        //console.log(packageDefinition);

        // Get protobufer descriptor
        const buffer = descriptor.getBuffer();
        //console.log(buffer);

    })();

}catch(e){
    console.log(e);
