Golang Grpc Realworld Example Save

Go/GRPC codebase containing RealWorld examples (CRUD, auth, advanced patterns, etc) that adheres to the RealWorld spec and API.

Demo    RealWorld

This codebase was created to demonstrate a fully fledged fullstack application built with golang/grpc including CRUD operations, authentication, routing, pagination, and more.

How it works

• Using grpc-gateway as reverse-proxy server which translates a RESTful JSON API into gRPC.

• Using Go to implement realworld backend server.

  • grpc: grpc-go
  • auth token: jwt-go
  • ORM: gorm
  • logging: zerolog

• Using MySQL to store data.

Getting started

The app listens and serves on 0.0.0.0:3000.

• docker-compose

  $ docker-compose up -d
  

• local

  • Install Go 1.19+, MySQL
  • set environment variables to connect database like this.

  $ go run server.go # run grpc server
  $ go run gateway/gateway.go # run grpc-gateway server
  

Unit test

• docker-compose

  $ docker-compose run app make unittest
  

• local

  $ make unittest
  

E2E test

$ make e2etest
