Github Actions Ranking (June 18, 2020)

Github Actions is a CI/CD platform that gained a lot of popularity recently. I participated in building ⭐️ Lighthouse CI Action and was curious how well it performs.

But Github Marketplace UI shows no ranking information. Essentially, It's a search with random results; at least, I don't understand the order. I couldn't find ⭐️ Lighthouse CI Action in Continuous integration category after browsing 50 available pages (Each page shows 20 results, so it's possible to see only 1000 results, but CI category has 1469 😐).

I decided to build a custom script that crawls all categories and use Github Search (example query) to estimate usa

export const h=(t,p,...c)=>({t,p,c,k:p&&p.key})
export const render=(e,d,t=d.t||(d.t={}),p,r,c,m,y)=>
// arrays
e.map?e.map((e,p)=>render(e,d,t.o&&t.o[p])):
// components
e.t.call?(e.i=render((render.c=e).t(Object.assign({children:e.c},e.p),e.s=t.s||{},t=>
render(Object.assign(e.s,t)&&e,d,e)),t.i||d,t&&t.i||{}),d.t=t=e):(
// create notes
m=t.d||(e.t?document.createElement(e.t):new Text(e.p)),
// diff props
