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 🙏

nodejs的一些常用封装

比如会包括一些redis的链接和redis命令的封装。

安装

npm i general-node-utils -S

可以这样使用:

var {redisConn} = require('general-node-utils');
var redis = redisConn();
redis.keys("*").then(data=>{
  console.log(data);
  });

es6中也可以这样使用:

import {redisConn} from 'general-node-utils';
require('general-js-utils');
const redis = redisConn();
redis.keys("*").then(data=>{
  - console.log(data);
});

所有方法列表:

redisConn(options)

用于redis连接,options参见https://github.com/luin/ioredis/blob/master/API.md

defaultOptions = {
  port:6379,
  host:'127.0.0.1',
  family:4,
  db=0
}

mhgetall(redisConn,keysArr,options)

批量获取hash类型内的全部数据。

输入一个redis连接,以及想获取的hash的keys的数组,options可选,有一个参数showEmptyObject,默认是false,表示如果没有这个key的话不作为数组的一个元素输出,如果为true则会在对应项里输出一个空对象

mkeysexsist(redisConn,keysArr)

批量检测keys是否存在

输入同上,输出类似为[true,false,true]

mzcount(redisConn,keysArr,options)

批量获取各个有序集合内的成员数量,options可选,有2个参数,min和max,分别表示有序集合内score的范围。 输出同上

mgetjson(redisConn,keysArr)

批量获取各个类型为string,并且存放的是json字符串的集合,json字符串将会自动解析成对象。
