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 🙏

  • 可自定义redis前缀
  • 基于ioredis
  • 同时返回可操作的redis client实例
  • 配置简单
  • 自动将过期时间转化为东八区时间
  • 自动重新连接

使用方法

  • 配置及初始化
// session.js
import store from 'sessionRedisStore';
let session = store({
    key: 'sid',
    cookie: {
        signed: false, //是否要做签名
        path: '/', //cookie 的路径,默认为 /'
        domain: '.myDomain.com', //cookie 的域
        secure: false, //表示 cookie 通过 HTTP 协议发送,true 表示 cookie 通过 HTTPS 发送。
        httpOnly: true, //表示 cookie 只能通过 HTTP 协议发送
    },
    store: {
        host: '127.0.0.1', // redis地址
        port: 6379, // redis端口
        ttl: 360, // session及cookie的失效时间,单位:秒
        db: 0, // 数据库index
        keyPrefix: 'myproject:session:prefix:' // redis存储前缀
    }
})
export default session
  • 引用中间件
import Koa from 'koa'
import session from './session';
const app = new Koa()
app.use(session)
import session from './session';
let client = store.client

const kickOffUser = async function(userId) { // 清除指定用户的session信息,踢该用户下线
    var sessionId = await client.get(userId);
    console.log(`kickOffUser: sessionId is ${sessionId}`)
    if (sessionId) { // 存在失效用户session,则删除旧记录
        await client.del(sessionId)
    }
    return sessionId
}
