Co-depends NPM

co-depends

co-depends is a suite of web components based on code-pen entries.

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:

<body>
    ...
    <iframe src="../css-minesweeper.html"></iframe>
    <co-depends-css-minesweeper></co-depends-css-minesweeper>
</body>

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.

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.
