Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

简介

sonorpc是一个轻量级、高性能的node rpc框架,由Registry(注册中心)、Provider(服务提供者)、Consumer(服务消费者)组成,提供远程方法调用、负载均衡、服务自动注册和发现功能。

如何使用

npm install sonorpc

import { createProvider } from "sonorpc"

Provider服务提供者

创建服务

DemoService.js

const { Service } = requie("sonorpc");

class DemoService extends Service {
    async sayHello(arg1, arg2) {
        const result = await this.ctx.mysql.query('select * from user');
        return {
            success: true,
            data: result
        }
    }
}

启动Provider服务

scripts/start.js

const { createProvider } = requie("sonorpc");
const provider = createProvider({
    // 注册服务提供者名称
    name: 'user',
    // 日志类示例
    logger: console,
    // 上下文
    ctx: {
        mysql: mysql.createPool(config.mysql)
    },
    // 监听端口
    port: 3005,
    // 服务类
    serviceClasses: [DemoService],
    // 注册中心配置
    registry: {
        // 注册中心地址
        host: '127.0.0.1',
        // 注册中心端口
        port: 3006
    }
});

provider.start(() => {
    console.log('服务已启动');
});

Registry注册中心

scripts/registry.js

const { startRegistry } = require('sonorpc');

startRegistry({
    port: 3006
});

Consumer服务消费者

创建消费者

consumer.js

const { registerConsumer } = require('sonorpc');

const consumer = registerConsumer({
    // 服务提供者名称
    providerName: 'user',
    port: 3006
});

module.exports = consumer;

调用服务

DemoService.js

const consumer = require('../consumer');

class DemoService {
    testMe(...args) {
        return new Promise((resolve, reject) => consumer.invoke('demo.testMe', args, (err, data) => {
            err ? reject(err) : resolve(data);
        }));
    }
}
