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 🙏

xz-ipnet

v1.0.2

Published

国内ip地区查询,基于ipip.net免费数据库

Downloads

Readme

IP地理位置查询

安装

npm install xz-ipnet --save

普通用法

var ipnet = require('xz-ipnet')();
console.log(ipnet.find("180.109.81.135"));
//output: [ '中国', '江苏', '南京', '' ]

koa用法

var ipnet = require('xz-ipnet')();
var koa = require('koa');

const app = new koa();
//将ipnet对象加到ctx中,方便全局调用
//ipnet一次将dat文件加载到内存中,不会每次请求都加载dat文件
app.use(async function(ctx,next) {
  ctx.ipnet = ipnet;
  await next();
});

app.use(async function(ctx){
	ctx.body = ipnet.find("180.109.81.135") || 'null';
})

自定义字典文件

本模块采用的是 ipip.net 的免费版ip数据库,格式为dat文件,默认有一个位于包根目录下。

然而考虑到地址库可能会更新,可指定dat文件。

var ipnet = require('xz-ipnet')('./newip.dat');

关于地址库

由于是免费版,所以只精确到市,不包含行政区,不过整体文件就比较小,特别适合特定的场景。

我再说两句

由于时间关系,就没写单元测试,不过也就那么一个方法,测试了几个ip还是ok,我项目中也在用,出问题第一时间修复。
