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/cancel-token

取消请求。

安装

npm install @prequest/cancel-token

使用

对于业务开发者来说,如何利用 cancelToken 取消请求?

import { prequest } from '@prequest/xhr'
import CancelToken from '@prequest/cancel-token'

const source = CancelToken.source()

prequest.request({
  path: '/api',
  cancelToken: source.token,
})

source.cancel()

你也可以初始化一个请求实例,在页面或组件卸载时,取消所有请求

import { create } from '@prequest/xhr'
import CancelToken from '@prequest/cancel-token'

const source = CancelToken.source()

const prequest = create({ cancelToken: source.token })

useEffect(() => {
  prequest('/api1')
  prequest('/api2')
  prequest('/api3')
  prequest('/api4')

  return () => {
    source.cancel()
  }
}, [])

!> 注意:CancelToken 是一次性的,即取消请求之后,再发起请求,会被直接取消。如果有类似需求,建议在调用完取消后,再为 source 重新赋值一个 CancelToken.source

集成到请求库

对于库开发者,如何将 CancelToken 集成到请求库中?

首先需要设计将 cancelToken 作为可选参数

import CancelToken from '@prequest/cancel-token'

interface Request {
  cancelToken?: CancelToken
}

其次在 adapter 函数中,处理 cancelToken.

function adapter(opt) {
  const { cancelToken } = opt

  return new Promise((resolve, reject) => {
    if (cancelToken) {
      cancelToken.promise.then(() => {
        // 调用原生请求的方法,取消请求。一般用于请求内核提供了取消请求方法的情况下
        nativeRequest.abort()

        reject(new Error('cancel'))
      })
    }
  })

  // ...some code
}
