community-protocols VS reqwest

> 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.

What's an example of this for, say, libcurl? On my system it has a tiny number of recursive dependencies, around a dozen. [0] Furthermore if I want to write a C program that uses libcurl I have to download zero bytes of data ... because it's a shared library that is already installed on my system, since so many programs already use it.

I don't really know the appropriate comparison for Rust. reqwest seems roughly comparable, but it's an HTTP client library, and not a general purpose network client like curl. Obviously curl can do a lot more. Even the list of direct dependencies for reqwest is quite long [1], and it's built on top of another http library [2] that has its own long list of dependencies, a list that includes tokio, no small library itself.

In terms of final binary size, the installed size of the curl package on my system, which includes both the command line tool and development dependencies for libcurl, is 1875.03 KiB.

[0] I'm excluding the dependency on the ca-certificates package, since this only provides the certificate chain for TLS and lots of programs rely on it.

ReductStore was rewritten from C++ to Rust a few months ago. We are delighted to be part of the Rust community and have taken a new step towards Rust with the Client SDK. The SDK is powered by reqwest and enables asynchronous integration of the database into Rust applications:

From what I could turn up when googling the specific error lines (here), it has something to do with the crate mio not having support for WASM, but I don’t understand what’s being said on this thread.

You can use the tauri-plugin-deep-link crate to register your app as a protocol handler. After you get your code, you can exchange it for an auth token in the same manner as the Electron guide, but for Rust you can use reqwest for the HTTP call.

When starting out, we made some design decisions at the backend. The decision will allow us to independently test the service without interfering with the real application using a term called integration testing. We'll utilize two "dev" packages: reqwest and fake. Dev dependencies only get introduced into your application in development or during testing. In production, they are not included:

It's possible, you will want to use crates like https://docs.rs/reqwest/ to download the page and https://docs.rs/scraper/ to extract elements from the page.

Rust allows me to mainly only run the application to confirm things work from a business perspective.

For people starting out building stuff in rust - understand that there is a distinction of async code and libraries and can lead to confusing compiler errors if you don't realize there is a distinction. It's simple in hindsight but did cause me to waste hours barking up the wrong trees at first. Other wise just learn about `match` and Result/Option types asap, they're fundamental.

https://github.com/http-rs/tide tide is great to create an http server / routes

https://github.com/djc/askama I use this to template out HTML and it checks all my boxes, dynamic data, passing in functions, control flow.

https://github.com/launchbadge/sqlx sql interface for a variety of backend, async safe.

https://github.com/seanmonstar/reqwest http client to make requests

Rust is amazing, don't let the initial few speed bumps discourage you - building real things with rust is no more challenging today than any other modern language stack.

Is there any this month in reqwest? I would like to show my interest in https://github.com/seanmonstar/reqwest/issues/39

The relevant issue seems to be https://github.com/seanmonstar/reqwest/pull/1753
