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

list-feature-flags

list-feature-flags is a command-line utility that searches through JavaScript and TypeScript files in a directory for feature flags and experiment keys, and outputs a sorted, unique list of them.

Installation

You can use this utility via npx without installing it:

npx list-feature-flags

Or, install it globally using npm:

npm install -g list-feature-flags

Usage

To use the utility, navigate to the directory containing your JavaScript or TypeScript files and run:

npx list-feature-flags --mode=featureFlags

Or, if you installed it globally:

list-feature-flags --mode=experiments

The utility allows two modes:

  1. featureFlags: This mode will search for any words matching the regular expressions \bf_\w*\b and \bF\w*Feature\b, then applies a series of transformations to convert CamelCase to snake_case, lowercasing the string, removing the trailing _feature part and finally ensuring the flag starts with _f.

  2. experiments: This mode will search for any words matching the regular expressions \be_\w*\b and \bE\w*Experiment\b, then applies a similar series of transformations as in featureFlags mode, but removes the trailing _experiment part and ensures the flag starts with _e.

In both modes, files in test, __mocks__, and node_modules directories are excluded from the search. The output lists are sorted and duplicates are removed.

If the --mode flag is not provided, the utility defaults to featureFlags.
