Sample gRPC Rust News Server

Overview

This repository contains a gRPC-based Rust server implementing CRUD operations for a news list. It features a batched GetNews API, allowing efficient retrieval of multiple news items.

Features

• CRUD Operations: Create, Read, Update, and Delete news items.
• Batched News Retrieval: Fetch multiple news items in a single request.
• gRPC Interface: Efficient and modern protocol for inter-service communication.

Prerequisites

Before you begin, ensure you have installed:

• Rust
• Shuttle CLI

Installation

Running the Server Locally

cargo shuttle run --port 50051

Deploying to Shuttle.dev

Deploy the server with:

cargo shuttle init

Follow the prompts:

1. Select your project name
2. Choose 'Empty (no framework)' when prompted

Then deploy with:

cargo shuttle deploy

gRPC API

The server uses the following gRPC API defined in news.proto:

syntax = "proto3";
import "google/protobuf/empty.proto";

package news;

message News {
  int32 id = 1;
  string title = 2;
  string body = 3;
  string postImage = 4;
}

service NewsService {
  rpc GetAllNews (google.protobuf.Empty) returns (NewsList) {}
  rpc GetNews (NewsId) returns (News) {}
  rpc GetMultipleNews (MultipleNewsId) returns (NewsList) {}
  rpc DeleteNews (NewsId) returns (google.protobuf.Empty) {}
  rpc EditNews (News) returns (News) {}
  rpc AddNews (News) returns (News) {}
}

message NewsId {
  int32 id = 1;
}

message MultipleNewsId {
  repeated NewsId ids = 1;
}

message NewsList {
  repeated News news = 1;
}

Reflection api

The server supports reflection api by default
