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 🙏

安装

首选需要指定 npm仓库为内部仓库 registry.npm.tongdun.cn 然后执行npm install @td/node-shutter 或 yarn add @td/node-shutter

配置说明

  • hostList shutter服务地址,多个用逗号隔开,可选值见shutter首页
  • application 配置所属应用
  • group 配置所属分组
  • environment 配置所属环境,默认dev,可选值见shutter首页
  • SecretKey 密钥,申请入口见https://my.tongdun.cn/#/accesskey
  • AccessKey 密钥,申请入口见https://my.tongdun.cn/#/accesskey
  • watchIntervalTime 定时更新配置间隔时间,单位ms, 默认30000ms,开启监听远端配置文件时生效

API说明

  • addProperties(app: string, locations: string[]) 添加需要读取的shutter配置,locations指文件名
  • addWatch(app: string, handle: () => void) 监听文件变化
  • getProperty(key: string) 根据key值获取shutter配置项值
  • fetchRemoteData() 读取远端配置,通常在addProperties添加完所有需要读取的配置后,一次获取远端配置即可

使用示例

const Shutter = require('@td/node-shutter').default;
const shutter = new Shutter({
    hostList: '10.57.17.39:8188',
    application: 'test',
    group: 'DEFAULT_GROUP',
    environment: 'dev',
    SecretKey: 'SecretKey',
    AccessKey: 'AccessKey'
});
// 添加需要读取的配置
shutter.addProperties('jdbc', ['jdbc.octopus-box.properties', 'jdbc.octopus-gaea.properties']);
shutter.addProperties('redis', ['redis.octopus-screen.properties']);
// 读取远端配置,应用启动后只需要调用一次即可
shutter.fetchRemoteData();
// 监听远端配置变化
shutter.addWatch('jdbc'); // 目前仅支持监听整个应用的所有文件
// 取出某个配置的值
shutter.getProperty('octopus-screen.redis.namespace') // 值为shutter上配置的octopus-screen

说明 配置文件会在本地缓存一份,当shutter服务端不可用时,会使用本地缓存
