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 🙏

@prequest/interceptor

拦截器中间件。

中间件模型可以更好的完成修改请求和拦截响应的需求,但为了方便习惯使用 axios 的用户,提供此中间件。

安装

npm install @prequest/interceptor

使用

import { prequest } from '@prequest/xhr'
import interceptorMiddleware from '@prequest/interceptor'

const interceptor = new InterceptorMiddleware()

// 修改请求参数
interceptor.request.use(
  request => {
    if (!request.path) throw new Error('can not find path')

    request.path = '/prefix' + request.path

    // 注意要将 request 参数返回
    return request
  },
  error => {
    console.log('modify request path fail', error)
    throw error
  }
)

// 修改响应
interceptor.response.use(
  response => {
    if (response.statusCode === 500) throw new Error('internal error')

    response.data = JSON.parse(response.data)

    // 注意要将 response 返回
    return response
  },
  error => {
    // 如果是某个错误
    if (error.message === 'internal error') {
      // 要进行什么操作

      return
    }

    // 否则将错误继续抛出
    throw error
  }
)

prequest.use(interceptor.run)
