Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Theme Customization (Expanse from Archetype Themes)
Actually I want to modify the Expanse theme from Archetype Themes in a way that its possible to implement an audio player (using Wavesurfer JS library) which keeps playing when a new page is loaded. So there cant be an entire page reload, I need to modify the theme so the main content is fetched instead.

Wavesurfer waveform not appearing
I'm trying to get a basic version of wavesurfer working. I followed the tutorial from this youtube video and downloaded the same code from the github. The buttons appear, but the waveform doesn't appear.

Does anybody know the code to that player?
Could be this though: https://github.com/katspaugh/wavesurfer.js

Svelte Performance Test | Frame Accurate Subtitle Display
Thanks so much! The timeline actually isn't as complicated as it may look. There are lots of really awesome projects to take inspiration from (e.g. WavesurferJS). The one thing I wanted to point out is that the component was much easier to build in Svelte than in Vue. When we had the timeline component in Vue it used dependencies from other projects (because they were readily available). With Svelte there was nothing to install from NPM so we built it from scratch... and it was actually a lot of fun! It also scales really nicely for larger projects!
