Proto Demo

This repo compares different ways of using Protobuf and gRPC in TypeScript and Node.js with using native TypeScript. It demonstrates two different use cases: Writing and reading from a database, and serving a gRPC service.

Usage

Use npm run <script> to run any of the demonstrates, which will take an object, serialize and deserialize it, and then print the output.

Options:

Script	Description
database:ts	A native TypeScript implementation of mock database interactions.
database:google	A google-protobuf implementation of mock database interactions.
database:pbjs	A Protobuf.js implementation of mock database interactions.
database:loader	A proto-loader-gen-types implementation of mock database interactions.
server:ts	A native TypeScript implementation of a gRPC service.
server:google	A google-protobuf and @grpc/grpc-js implementation of a gRPC service.
server:google-persistent	A google-protobuf and @grpc/grpc-js implementation of a gRPC service that stays open.
server:loader	A @grpc/proto-loader implementation of a gRPC service.
server:loader-persistent	A @grpc/proto-loader implementation of a gRPC service that stays open.
server:loader-google	A @grpc/proto-loader implementation of a gRPC server, with a google-protobuf and @grpc/grpc-js client.
enum:ts	A native TypeScript implementation of enum to string conversion.
enum:google	A google-protobuf implementation of enum to string conversion.
enum:pbjs	A Protobuf.js implementation of enum to string conversion.
enum:loader	A proto-loader-gen-types implementation of enum to string conversion.
proto	Regenerate the libraries with google-protobuf and pbjs.

npm run database:ts;
npm run database:google;
npm run database:pbjs;
npm run database:loader;
npm run enum:ts;
npm run enum:google;
npm run enum:pbjs;
npm run enum:loader;
npm run server:ts;
npm run server:google;
npm run server:loader;

Reflection

The server:loader version implements server reflection. One way to use this is to remove the line that closes the server and use grpcui:

go get github.com/fullstorydev/grpcui/...
go install github.com/fullstorydev/grpcui/cmd/grpcui
grpcui -plaintext localhost:9876
