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.

But these are typically filling the usecases of productivity applications, not ‘engines’.

Microsoft Word doesn’t run its grammar checker as an external service and shunt JSON over a localhost socket to get spelling and style suggestions.

Photoshop doesn’t install a background service to host filters.

The closest pattern I can think of is the ‘language servers’ model used by IDEs to handle autosuggest - see https://microsoft.github.io/language-server-protocol/ - but the point of that is to enable many to many interop - multiple languages supporting multiple IDEs. Is that the expected usecase for local language assistants and image generators?

If you tried writing code like the one above, your Rust LSP should already be telling you that what you're doing is unacceptable:

A language server is an external program that follows the Language Server Protocol. The LSP specification defines what type of messages a language server can receive, and also how it should respond. The idea here is that any tool that follows the LSP specification can communicate with a language server.

> There's a strange dance of IDEs coming and going, with their idiosyncracies and partial plugins.

The Language Server Protocol [1] is the best thing to happen to text editors. Any editor that speaks it gets IDE features. Now if only they'd adopt the Debug Adapter Protocol [2]...

The Gno Language Server (gnols) is an implementation of the Language Server Protocol (LSP) for the Gno programming language. It is similar to the equivalent “gopls” project for Go, as they can be plugged into your code editor through extensions and allow you to access handy features, such as autocompletion, formatting, and compile-time warnings/errors. Gnols makes writing code simpler, working with several editors to suit your preferences. To try it out, visit the CONTRIBUTING.md file, which contains instructions to get you started. Our current documentation targets Vim, Neovim, and SublimeText, but can likely be used with any editor that supports LSP. Feel free to contribute to improving Gnols and adding more features. It’s well-written, and simple to dive into the code and add more capabilities.

Honestly, you should read some of the docs [0] if these are the sorts of questions you're asking.

hey HN. this is a Language Server[0] designed specifically for Postgres. A language server adds features to IDEs (VSCode, NeoVim, etc) - features like auto-complete, go-to-definition, or documentation on hover, etc.

there have been previous some attempts at adding Postgres support to code editors. usually these attempts implement a generic SQL parser and then offer various "flavours" of SQL.

This attempt is different because it uses the actual Postgres parser to do the heavy-lifting. This is done via libg_query, an excellent C library for accessing the PostgreSQL parser outside of the server. We feel this is a better approach because it gives developers 100% confidence in the parser, and it allows us to keep up with the rapid development of Postgres.

this is still in early development, and mostly useful for testers/collaborators. the majority of work is still ahead, but we've verified that the approach works. we're making it public now so that we can develop it in the open with input from the community.

a lot of the credit belongs to pganalyze[1] for their work on libg_query, and to psteinroe (https://github.com/psteinroe) who the creator and maintainer of the LSP.

The nxls is a language server based on the Language Server Protocol (LSP) and acts as the “brain” of Nx Console. It analyzes your Nx workspace and provides information on it, including code completion and more.

LSP stands for "Language Server Protocol", which defines how a language server and an editor (client) can communicate to provide code navigation, completion, etc. (source). Traditional IDE's would have something similar to this baked-in already, but proprietary to their software/language; whereas LSP is an open standard, so anything could implement it.
