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 🙏

HTTP-HEADER-PARSER

HTTP请求头转换工具

安装

npm install --save http-header-parser

头解析

基本用法:

//导入
import { parseRequest, parseResponse } from 'http-header-parser'			//这里值演示request转换,response也是一样的
//创建转换器
let parser = parseRequest()
//监听头消息
parser.on('header', header=>{
	//得到请求头
	console.log(header)
	console.log(header.toString())	//CONNECT home.netscape.com:443 HTTP/1.0\r\nUser-agent: Mozilla/4.0\r\n\r\n
})
//写入数据
let buffer = new Buffer('CONNECT home.netscape.com:443 HTTP/1.0\r\nUser-agent: Mozilla/4.0\r\n\r\n这里的这些数据会被忽略掉')
parser.write(buffer)

//也可以将数据一点点写入,例如:

let bufferList = [
	new Buffer('CONNECT home.netscape.c'),
	new Buffer('om:443 HTTP/1.0\r'),
	new Buffer('\nUser-agent: Mozi'),
	new Buffer('lla/4.0\r\n'),
	new Buffer('\r\n这里的这些数据会被忽略掉'),
]
bufferList.forEach(buf=>parser.write(buf))

事件

  • header 转换完毕,得到头
  • error 转换出错
  • line 获取到一行数据的时候
  • end 转换结束(首行出错时会结束)

创建头

可以使用RequestHeader和ResponseHeader这两个类来创建请求头和响应头

import { RequestHeader, ResponseHeader } from 'http-header-parser'

let header = new RequestHeader('GET', 'http://www.baidu.com/index.html', 'HTTP/1.1')
header.put('User-Agent', 'Wget')
header.toString()
/*
生成结果如下:
GET http://www.baidu.com/index.html HTTP/1.1
User-Agent: Wget
(这里是一个空行)
*/
