engined-grpc

gRPC service for engined.

Installation

Install via NPM:

npm install engined-grpc

Implement gRPC Server

start gRPC server agent service in engined, see example below:

const { Manager } = require('engined');
const { Server } = require('engined-grpc');
 
gRPCService = Server();
 
const main = async () => {
 
    // Create manager
    let serviceManager = new Manager({ verbose: true });
 
    // Adding agent to manager
    serviceManager.add('gRPCServer', gRPCService);
 
    // Start all services
    await serviceManager.startAll();
};
 
main();

Customized Router

engined-grpc is based on Groa.js which is useful gRPC middleware framework. We can create own router service to load proto file and get groa-router object to setup handler.

const { Router } = require('engined-grpc');
const path = require('path');
 
// Create a router service which will load specific proto files
const RouterService = Router({
    protoFiles: [
        path.join(__dirname, 'proto', 'example.proto')
    ]
});
 
module.exports = class gRPCRouterService extends RouterService {
 
    async initialize(grpcAgent) {
 
        // Get groa-router object
        let router = grpcAgent.getRouter();
 
        // Setup handler
        router.rpc('/pipespool.PipeNetwork/Test', async (ctx) => {
 
            // Return
            ctx.body = {
                content: 'Test!!!'
            };
        });
    }
};
