Why I use web components

This is some sort of answer to recent posts regarding Web Components, where more than a few misconceptions were delivered as fact.

Let's start by defining what we are talking about.

The Web Components Umbrella

As you can read in the dedicated GitHub page, Web Components is a group of features, where each feature works already by itself, and it doesn't need other features of the group to be already usable, or useful.

  padding: 2rem;
  margin: auto;
}

Conventional Commit Messages

See how a minor change to your commit message style can make a difference.

Tip

Take a look at git-conventional-commits , a CLI util to ensure these conventions, determine version and generate changelogs

	// $ node hls-repeat.js
	// Example (2 reps): http://localhost:8000/slate-consuo2.mp4/master.m3u8?r=2
	// where r is how many times the VOD to be repeated

	const { HLSProxy } = require("@eyevinn/hls-proxy");
	const HLSRepeatVod = require("@eyevinn/hls-repeat");

	const proxy = new HLSProxy({
	originHandler: async () => {
	// Origin where the VOD is found

	<style>
	.git-graph {
	text-align: left;
	line-height: 1;
	}
	.git-graph-row {
	clear: both;
	text-align: left;
	}
	.git-graph-cell {
