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 🙏

Smiley Library

A collection of useful Node.js functions and utilities.

These are functions I use often but are too simple to have their own package.

Functions

zeroPad(string, totalLength) -> String

Zero pad the given number into a string with the given total length.

hexDump(Buffer) -> String

Render the bytes of the given Buffer to a hex-editor-like format.

isUUID(string) -> Boolean

Uses a Regex to test the given string for the UUID format.

iecToDecimal(string) -> Number

Converts an IEC size (e.g. 4.0K) to a full decimal Number (e.g. 4096)

titleCase(string) -> String

Converts a string to Title Case. Hyphens and underscores are converted to spaces.

getNetworkInterfaces() -> Array

Get an array of network interfaces in a different format than the typical os.networkInterfaces(). Makes traversing the interfaces easier.

getExternalIPAddress() -> String

Return an IP address marked as external in os.networkInterfaces(). No guarantees about internet access.

findModuleRoot(moduleName) -> String

Find the root of the given module defined as the first directory above the module's entry point with a package.json file.

debounce(function, waitMS, runImmediate) -> function

Debounce the given function by preventing multiple executions within the given waitMS time. If runImmediate is true, the function will be executed immediately the first time.
