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

这是一套基于 Daze.js 的 Dubbo 的扩展,提供了服务端和客户端的一整套解决方案。

开始

安装

$ npm install --save @dazejs/dubbo-provider

加载服务提供者

添加 DubboServiceProvidersrc/config/app.ts 配置中

import { DubboServiceProvider } from '@dazejs/dubbo-provider';

export default {
  // ...
  providers: [
    // ...
    DubboServiceProvider
  ]
  // ...
}

添加/修改配置中心设置

src/config/ 目录下创建 dubbo.ts 配置文件:

export default {
  default: {
    type: 'zookeeper',
    host: '127.0.0.1:2181',
  }
}

自定义服务器IP地址(默认自动获取,某些情况下自动获取的IP地址可能不正确), 在刚才的配置文件中新增属性:

export default {
  // ...
  ip: '100.100.100.100'
  //...
}

也可以使用 @dubbo.ip('100.100.100.100') 来为每个消费者或者提供者单独设置(优先级大于全局)

使用

服务端 (Provider)

定义提供者
import { DubboProvider, dubbo } from '@dazejs/dubbo-provider';

@dubbo.registry('default')
@dubbo.interface('com.daze.dubbo.service.Demo')
@dubbo.ip('100.100.100.100') // 自定义 ip 地址,一般情况下无需使用,自动获取即可
export default class extends DubboProvider {
  @dubbo.method()
  sayHello(name: string) {
    return `Hello ${name}`;
  }
}

客户端 (Consumer)

定义消费者
import { DubboConsumer, dubbo } from '@dazejs/dubbo-provider';

@dubbo.registry('default')
@dubbo.interface('com.daze.dubbo.service.Demo')
export default class extends DubboConsumer {
}
注入并使用
import { Controller, http, inject } from '@dazejs/framework';
import { java } from '@dazejs/dubbo-provider';
import DemoConsumer from '../dubbo/consumers/demo';

export default class extends Controller {

  @inject(DemoConsumer) demoConsumer: DemoConsumer;

  @http.get()
  async index() {
    const res = await this.demoConsumer.invoke('sayHello', [java.String('dazejs')]);
    return res;
  }
}
