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 🙏

简介

这是一个使用 JS 编写的 DFA 算法实现包,兼容 Node 环境与 Browser 环境,使用方法如下:

// 安装dfafilter包
npm install dfa-filter

// browser 环境使用
import dfaFilter from 'dfa-filter'

// node 环境使用
require(dfaFilter)

/**
//大括号写类型
@param{string}text 待检测的字符串
@param{string}tag 用于替换敏感词的字符。默认“*”
@param{Boolean}countMode true为使用过滤替换模式,false是使用计数模式。默认“false”
@returns 返回过滤后的文本或者敏感词计数
*/
dfaFilter("the text for test", "*", flase)

DFA 算法

DFA敏感词检测算法是一种高效的字符串匹配算法,可以快速地在一段文本中检测是否包含敏感词。

DFA(Deterministic Finite Automaton)敏感词检测算法是一种基于有限状态自动机的高效字符串匹配算法,通过将敏感词构建成一棵状态转移图,将文本逐个字符进行匹配,并根据状态转移图的规则进行状态的转移来检测是否包含敏感词,具有快速、高效的特点,在实际应用中被广泛使用。
