A complete framework for gRPC-node.js

const grpc = require('grpc');
// takes in a js object, returns a grpc metadata object with the same properties
module.exports = function generateMeta(metaObject, options) {
  if (metaObject === undefined) {
    return new grpc.Metadata();
    }
  const metadata = new grpc.Metadata(options);
  const keys = Object.keys(metaObject);
  for (let i = 0; i < keys.length; i++) {
    metadata.set(keys[i], metaObject[keys[i]]);
  }
  return metadata;
}
