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

$ npm i @kecoyo/egg-qiniu --save

使用

// config/plugin.js
exports.qiniu = {
  enable: true,
  package: '@kecoyo/egg-qiniu',
};

配置

// {app_root}/config/config.default.js
exports.qiniu = {
  default: {
    ak: '', // Access Key
    sk: '', // Secret Key
    useCdnDomain: true,
    isLog: true,
  },
  app: true,
  agent: false,

  // 单实例
  // 通过 app.qiniu 直接使用实例
  // client: {
  //     zone: '', // Zone_z0 华东, Zone_z1 华北, Zone_z2 华南, Zone_na0 北美
  //     bucket: '',
  //     baseUrl: null, // 用于拼接已上传文件的完整地址
  // }

  // 多实例
  // clients: {
  //     // 可以通过 app.qiniu.get('myImage'), app.qiniu.get('myText') 获取实例
  //     myImage: {
  //         zone: '', // Zone_z0 华东, Zone_z1 华北, Zone_z2 华南, Zone_na0 北美
  //         bucket: '',
  //     baseUrl: null, // 用于拼接已上传文件的完整地址
  //     },
  //     myText: {
  //         zone: '', // Zone_z0 华东, Zone_z1 华北, Zone_z2 华南, Zone_na0 北美
  //         bucket: '',
  //     baseUrl: null, // 用于拼接已上传文件的完整地址
  //     },
  // },
};

请到 config/config.default.js 查看详细配置项说明。

使用

  • 通过app.qiniu调用函数,在配置文件中已经固定bucket

  • 在多实例中进行movecopy时,可以通过getBucket()获取本实例的bucket

  • 单实例中:

    app.qiniu.uploadFile(key, file);
  • 多实例中

    const image = app.qiniu.get('myImage');
    const imageBak = app.qiniu.get('myImageBak');
    
    const result = image.copy('p1.png', imageBak.getBucket(), 'p1_bak.png', true);
