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 🙏

koa2-static2

项目介绍

  • 基于 koa2、koa-static 中间件扩展带协商缓存的中间件

功能

  • 遵循 HTTP 协议缓存机制
  • 基于及集成 koa-static
  • 支持协商缓存
  • 可配置开启文件类型(默认禁止 HTML 文件缓存)

安装

  • (c)npm install koa2-static2 -D

使用

基础使用

默认开启协商缓存并禁止 HTML 文件缓存,在静态资源中每次都会发送请求检查服务端是否有更新

const koa2Static2 = require('koa2-static2');

const Koa = require('koa');

const path = require('path');

const staticPath = path.resolve(__dirname, './static');

const app = new Koa();

koa2Static2.install(app, staticPath);

app.listen(3000);

console.log('http://localhost:3000');
强制缓存优先(推荐)

浏览器先检测是否已经开启强制缓存,在强制缓存时间过期之后再发送请求检查服务端是否有更新

koa2Static2.install(app, staticPath, {
  maxAge: 10000
});
过滤指定资源

通过配置项指定 excludeExtensionCache 指定需要被忽略的文件类型,由于直接覆盖默认配置如果禁止 html 类型扔需手动传入

koa2Static2.install(app, staticPath, {
  maxAge: 10000,
  excludeExtensionCache: ['html', 'css']
});
koa-static 源用法

koa2Static2 本身是一个函数,基于 koa-static ,所以 api 保持一致

app.use(koa2Static2(staticPath, options));

API

  • function
    • koa2Static2
      • param 和 koa-static 一致
      • return
        • function <Function>
  • methods
    • install
      • param
        • koaApp <Object> koa 实例
        • staticPath <String> 静态资源目录、同 koa-static 第一个参数
        • options <Object> 同 koa-static 第二个参数
          • excludeExtensionCache 继承参数、参考上面示例
          • maxage
          • setHeaders
          • ...
      • return
        • void

其他

  • 若使用 setHeaders 中设置 Cache-ControlPragmaLast-ModifiedEtag 将无效
