community-protocols VS Mithril.js

Some good patterns here. An Event with a callback (what you're calling [context protocol](https://github.com/webcomponents-cg/community-protocols/blob...)) I think will prove useful

> except that "reactivity" does not meet the bar of developers collectively having landed on a solution to a common problem

Now that everyone seems to be in love with signals, there is work going on in the web components community group to prepare a spec for a signal (or observable, not sure what they are trying to call it) primitive [0]. It seems that they are getting ready to bring it to TC39 as a proposal.

(In the meantime, the Observable primitive from rxjs been given a go-ahead for browser implementation. There is a proposal ready [1], and I think I heard that it may already be in Chrome behind a flag [2].

So yeah; it's gonna be fun. Especially if both groups call their primitive Observable :-)

The custom element spec definitely only deals with the mechanics of when are where to run your component's lifecycle code - it says nothing about data. So your choices are basically property accessors, which are interoperable, but require prop-drilling for global-ish data, or something proprietary like a state management library.

The Web Components Community Group (WCCG) is offering something of a third way with the community protocols: https://github.com/webcomponents-cg/community-protocols

The Context protocol provides tree-scoped ambient data in an interoperable way. It's implemented by Lit and FAST (I believe). It doesn't replace a data store, but it's often used to provide data stores to components, and at least reduce some coupling.

Did you know events can also carry promises? A great showcase of this pattern is the Pending Task Protocol by the Web Components Community Group. Now, "Pending Task Protocol" sounds very fancy, but really, it's just an event that carries a promise.

If you’re coming from the Angular world, you probably appreciate the great dependency injection (DI) mechanism they have. You can centrally define some services and reuse them across your app, without thinking about passing on props from component to component - the DI system takes care of it. Lit provides something similar via the [@lit-labs/context](https://lit.dev/docs/data/context/) package. It’s based on the Context Community Protocol and similar to React’s context API.

Fundamentally it is an event based mechanism to access state or "context" from ancestores of a component node. Based on the Web Components Context Protocol RFC which in turn is inspired by React's Context Api, the key purpose is to solve the problem of prop drilling.

The conversation led to the creation of https://github.com/webcomponents-cg/community-protocols. So there is some effort to standardize at least on convention for these higher-order considerations, but working through this and how opinionated it is made me recognize even more that this has a lot of similarities to a different group building a different framework. Tricky balance.

I’m pretty actively following a lot of the web components community so I thought I would jump in here with some hopefully helpful information. Depending on what you mean by SEO it’s worth noting that for a while now Google and I believe Bing and a few others haven’t had any kind of requirement to pre-render content. You can just serve standard web components or any kind of SPA style front end and it will get indexed just fine, no penalties and no real issues unless you’re doing something particularly strange.

However, one of the more exciting projects in the web components space (lit.dev) now also supports proper SSR as well which is a very new thing in the world of web components. They are trying to build it in such a way that any other library can take advantage of through a common interface.

In fact there are some kind of early stage talks happening over here https://github.com/webcomponents/community-protocols where a bunch of companies like Google, Adobe, ING and others are trying to develop some open protocols on a whole bunch of topics to improve interoperability between various libraries so that no one has to buy in 100% to any one setup.

I really like Mithril.js (https://mithril.js.org/), which is, IMO, as close as it gets to web IMGUI. It looks a lot like React, but rendering happens manually, either on each event or with a manual m.redraw() call.

maybe you'll be interested to know v3 is in active development

I also find Tachyons or similar Atomic CSS libraries to also simplify CSS issues in a more maintainable way -- also with no compile step.

Mithril JS is an excellent JS framework for writing web and mobile apps. It describes itself as:

Mithril is an excellent JS framework, tiny and powerful. Like with another JS frameworks you can write components - a small piece of code solving a dedicated subtask.

I don’t enjoy React much, but (as I’ve commented before) I do love Mithril (https://mithril.js.org). Immediate-mode UI via a vDOM, like React, but small, simple, and with none of the reactivity complications. I’d never go back to building apps with pure JS.

You can find more information about Mithril.js on its official website.

The idea of nested function calls to build HTML is not new. Back in the hey-day of JS frameworks, this was a common vdom pattern. I kinda miss [MithrilJS](https://mithril.js.org/#dom-elements)
