Description

Example and Template about Transcoding HTTP to GRPC with Golang and Mongodb. Fyi, GRPC is modern open source high performance Remote Procedure (RPC) framework that can run in any environtment. It can efficiently connect services in and across data centers with pluggable support for load balancing, tracing, health checking and authentication. It is also applicable in last mile of distributed computing to connect devices, mobile applications and browsers to backend services. gRPC is based from protocol buffer which is an input schema that will be carried out by the client or user.

In this project, I provide examples or templates about http to gRPC transcoding. Actually, gRPC itself is based on HTTP v2 but is not published. So, Google Cloud Endpoint itself supports transcoding http to grpc, more or less the schema is like this.

Endpoint

  • GRPC
Endpoint Description Method
TodoService/CreateProduct To create todo POST
TodoService/FindById To get todo by id GET
TodoService/Update To update todo by id PUT
TodoService/Delete To delete todo by id DELETE
TodoService/FindAll To sell all todo GET
  • REST
Endpoint Description Method
/v1/todo To create todo POST
/v1/todo/{id} To get todo by id GET
/v1/todo/{id} To update todo by id PUT
/v1/todo/{id} To delete todo by id DELETE
/v1/todo To sell all todo GET

Usage

1.1 Usage with Golang

Run this command to running download all module

go mod tidy

then running file server.go to run the server

go run server.go

and the output will be like this

2023/08/08 14:26:20 GRPC Server running on localhost:40000
2023/08/08 14:26:20 HTTP Server running on localhost:8080

1.2 Usage with Docker

Run this command to download docker-compose (this command for linux)

sudo apt install docker-compose -y

then running this command

docker-compose up -d

and service will be running on port 40000 to GRPC and 8080 to REST

For example schema to input in GRPC you can see in example folder
