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 🙏

buffer-patch

Buffer的多结构序列化模块,解决一块buffer中同时存在string,number和buffer的解析问题,提高解析性能

应用场景

一个数据结构如下:

var obj = {
	size: 156,
	name: 'jifeng',
	buffer: new Buffer('hell world')
}

常用的序列化方式是,先将当中的buffer转化为字符串,再做JSON序列化.反序列的时候,就是JSON的反序列化,然后再将字符串转化为buffer

这样的缺点非常明显,就是buffer转字符串,字符串转buffer消耗还是比较大的

buffer-patch 的作用就是解决这个问题,它自己定义一套的格式,可以对直接这种对象进行序列化和反序列化,减少性能消耗

不足: 现在出于性能考虑,现在暂且只支持一层结构的object

安装

npm install buffer-patch

用法


var bufferPatch = require('buffer-patch');
var obj = {
	size: 156,
	name: 'jifeng',
	buffer: new Buffer('hell world')
}

var buff = bufferPatch.encode(obj);

var newObj = bufferPatch.decode(buff)
