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 🙏

Readme

说明

egg插件,提供敏感词检测,替换功能。使用DFA算法,性能优秀

如果是超大的敏感词库,例如 1W 以上,如果对初始化词库时长敏感,可以使用以下方法查看初始化所消耗的时间

console.time('spend time');
app.fullSensitivewords.addWord('管理员');
console.timeEnd('spend time');

安装

$ npm i egg-full-sensitivewords --save

使用

// config/plugin.js
exports.fullSensitivewords = {
  enable: true,
  package: 'egg-full-sensitivewords',
};

示例

可以通过app.fullSensitivewords来调用

测试示例见 test/test-dfa.js

所有接口的示例如下:

// 初始化敏感词库,建议在启动的时候执行
app.fullSensitivewords.addWords(['天安门', '毛主席', '周总理']);
app.fullSensitivewords.addWord('管理员');

// 判断是否包含敏感词,返回值 true: 包含; false: 不包含
app.fullSensitivewords.containsDfa('我爱北京天安门'); // => true
app.fullSensitivewords.containsDfa('主席毛泽东同志'); // => false

// 获取含有的敏感词内容,返回值 字符串数组
app.fullSensitivewords.wordsDfa('我爱毛主席和周总理'); // => ['毛主席', '周总理']

// 替换敏感词,当once=true时,对于每一个出现的敏感词,只替换一次。默认 once = false
app.fullSensitivewords.replaceDfa('我是管理员', '*', true); // => 我是*
// 替换敏感词, 当once=false时,对于每一个出现的敏感词,按照其长度替换。默认 once = false
app.fullSensitivewords.replaceDfa('我是管理员', '*', false); // => 我是***
