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

lux.js - real user monitoring

This repository contains the source code for lux.js, SpeedCurve's real user monitoring (RUM) script.

How to use lux.js

  2. Go to the Settings page and scroll to the bottom of the page
  3. Click on Edit RUM
  4. Click on the JS Snippet tab

Using lux.js in a SPA

See the SPA documentation.

Project goals

  1. Browser compatibility - lux.js runs and gathers basic metrics in every browser that supports ES3, while still gathering modern metrics from evergreen browsers.
  2. Small size - lux.js aims to be under 10 KB when minified and compressed.
  3. Low overhead - lux.js creates only a handful of event handlers and observers. Most metrics are calculated on-demand before a beacon is sent.

Local development

  • Compile the lux.js script with npm run build or npm run watch
  • Run the tests with npm run test
  • Check for linting errors with npm run lint and automatically fix them (where possible) with npm run lint-fix

Release process

  1. Propose changes in a pull request
  2. Once approved, merge changes to the main branch
  3. Increment the SCRIPT_VERSION constant on the main branch
  4. Add release information into CHANGELOG.md in this repo
  5. Create a new release in GitHub, following the naming convention and documentation process of previous releases
  6. Run npm run build to generate the lux.js bundles.
  7. Follow the rum-backend release process to deploy the updated lux.js bundles.
