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 🙏

将某设备的值以在某个时间段中小时的形式输出标准echart格式。

  1. 模块依赖@apla/clickhouse模块包

  2. 使用实例方法:

/**
 * 
 * @param {string} deviceId 设备编号
 * @param {string} monitorId monitor编号
 * @param {string} beginDate 开始时间
 * @param {string} endDate 结束时间
 * @param {string} type 统计类型(可选参数,目前只支持avg与sum,默认不传入为avg)
 * @param {number} decimal 保留几位(可选参数,默认不传入为0)
 */
const clickHouseToEchar = require('clickhouse-chart');
const options={
    clickHouse:{
        host:'',
        port:'',
        user:'',
        password:'',
        db:''
    },
    tableName=''
}
let ch2c = new clickHouseToEchart(options);
let deviceId = 'asudia-asd';
let monitorId = 'asdas-12sd';
let beginDate = '2017-10-27 11:12:55';
let endDate = '2017-10-27 13:00:00';
let type = 'avg';
let decimal = 2; //数值保留2位小数
let gap=5; //按5分钟间隔分组

ch2c.clickHouse2Echart(deviceId, monitorId, beginDate, endDate,type,decimal,gap).then((data) => {
    console.log('data:', data)
}).catch((err) => {
    console.log('err:', err)
});
  1. 输出结果
