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 🙏

[!CAUTION] 🚨 CRITICAL NOTICE: Data Bugs & Migration

Please be aware that the current data published to npm and the main branch contains bugs resulting in incorrect data.

To immediately resolve these data accuracy and compliance issues, updates via npm are completely deprecated and will stop.

The corrected data and new, compliant generation logic are already available in the main-test branch. We will be completely replacing the main branch with this structure very soon.

Action Required: We strongly urge all users to switch immediately to avoid using incorrect data. Please update your systems to download the latest data directly from our GitHub Releases.

CSV Format

ip_range_start, ip_range_end, country_code

ip_range_start and ip_range_end are either IP addresses, or IP addresses in numeric format (depending upon which files you choose) and these two fields represent an inclusive range of IP addresses for that data row.

For example, in the -ipv4.csv files, the CSV line: 1.0.0.0,1.0.0.255,AU would mean that any IP addresses between 1.0.0.0 and 1.0.0.255 (inclusive) are AU. In -ipv4-num.csv files, the equivalent line would be: 16777216,16777471,AU.

For example, in the -ipv6.csv files, the CSV line: 2001:200::,2001:200:ffff:ffff:ffff:ffff:ffff:ffff,JP would mean that any IP addresses between 2001:200:: and 2001:200:ffff:ffff:ffff:ffff:ffff:ffff (inclusive) are JP. In -ipv6-num.csv files, the equivalent line would be: 42540528726795050063891204319802818560,42540528806023212578155541913346768895,JP.

Please be careful when using IPv6 and IPv6-num files in your program, the numerical value exceeds 32bit unsigned integers, and you would need to use a 128bit unsigned integer.

country_code

country_code is the two-letter code defined in ISO 3166-1 alpha-2. You can get the country name, capital, continent, currency, languages, etc. from the country_code by Countries Database in JSON, CSV, SQL format.
