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 🙏

本地进程间通信模块

Readme

lrpc

项目源码摘自淘宝开源项目 pandora ,pandora 是一个淘宝开源的进程管理工具,里面进程间通信的模块很具有参考意义,所以将其单独分离出来做成一个项目。

安装

npm install lrpc --save

使用示例

服务器端广播数据

const assert = require('assert');
const {Server,Client,util} = require('lrpc');
const msg = {
    name: 'midway-messenger',
};
const action = 'midway-messenger-action';
const sockPath = util.getRandomSocketPath();
const server = new Server({sockPath});//直接使用在外部指定的socket地址
const client = new Client({sockPath});
new Promise(function(resolve) {
    client.ready(function() {
        resolve(client);
    });
}).then(function() {
    server.broadcast(action, msg);
    return new Promise(function(resolve) {
        client.on(action, (message) => {
            assert(message.name === msg.name);
            resolve();
        });
    });
}).then(function() {
    console.info('成功');
    assert(true);
}).catch(function() {
    assert(false);
});

客户端远程请求服务器端

const name = 'req-res-demo';
const {Server,Client} = require('../index');
const ACTION_CALC = 'actionCalc';
//服务器端代码
const server = new Server({//在内部使用 `name` 字段拼接 socket 地址
    name,
});

server.ready((err) => {
    if (err) {
        return console.error(err);
    }
    console.log('服务端创建成功');
});
server.on(ACTION_CALC,function(message,reply) {
    reply(message.a + message.b);
});
//客户端代码
const client = new Client({
    name,
});
client.ready(function(err) {
    if (err) {
        return console.error(err);
    }
    console.log('客户端创建成功');
});
client.send(ACTION_CALC,{a:1,b:2},function(err,res) {
    console.log('服务端返回数据',res);
});
