co-depends
co-depends is a suite of web components based on code-pen entries.
Entry 1. Text Scramble
Entry 2. Pure CSS Minesweeper
Being that this is css-only, it seems quite ridiculous to have to encode it in JS to make it a web component. So a deframed version can be seen in action here.
You reference it via an iframe:
... Or you can turn the beautiful css-only implementation into a js-only implementation as shown below:
It is quite interesting (to me) to compare the performance using Chrome Tools, with various throttling settings. I don't know how much of these differences are due to the way the throttling simulation works, vs. what one would see in the field.
| Test Case | Network Throttling | CPU throttling | First Meaningful Paint (sec) | DOM Loaded(sec) |
|---|---|---|---|---|
| Pure JS | Slow 3G | 6x | 6 | 9 |
| Pure JS | Slow 3G | 4x | 5 | 7 |
| Pure JS | Slow 3G | 1x | 4.5 | 5 |
| Pure Deframed HTML | Slow 3G | 6x | 8 | 8 |
| Pure Deframed HTML | Slow 3G | 4x | 3 | 5 |
| Pure Deframed HTML | Slow 3G | 1x | 2 | 2.5 |
It appears that the pure HTML (deframed version) outperforms when network is highly throttled, but the pure JS has an edge when CPU is highly throttled.
