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 🙏

基于Express框架的grpc网关

安装

npm install my-grpc-gateway

示例

const Express = require('express');
const bodyParser = require('body-parser')

const app = Express();

const Gateway = require('my-grpc-gateway');
const config = {
    zkConnectionString: '192.168.228.128:2181',
    prefix: '/api', // 所有对外接口的前缀
    rules: [
        {
            path: '/v1/test/*',
            // host: 'localhost:5007',
            serviceName: '/services/test'
        },
        // {
        //     path: '*',
        //     host: 'localhost:5007',
        // }
    ]
};
const router = new Gateway(Express, __dirname + '/protos', config).getRouter();

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));

app.use(router);

const port = 1452;
app.listen(port, () => {
    console.log('gateway listen on', port);
})

// 现在可以请求 http://localhost:1452/api/v1/test/1/books/2

config说明

  • zkConnectionString 用于服务发现时连接zookeeper,不需要zookeeper时可为空
  • prefix 所有对外接口的前缀,可为空
  • rules 用于代理多个服务时的路由匹配规则,如果有多个匹配 则只会匹配第一个
    • path http请求地址
    • host 目标服务。该字段不为空则优先使用该字段,若为空则使用serviceName
    • serviceName 服务名称,即zookeeper中节点路径。host与serviceName不能同时为空
