Laminar VS Metals

My quite niche open source project broke this threshold last year, via Github sponsorships. Of course, I put a lot of time into it, so it's not "passive income" or even "market rate income", but still, without these sponsorships I wouldn't be able to work on it so much.

The project is Laminar, a UI library for Scala.js https://laminar.dev

I've noticed that Laminar and the newly released Kyo point that they don't use a lot of macros as a feature. Laminar says "Easy to understand: no macros", while Kyo emphasizes "Note: defer is currently the only macro in Kyo. All other features use regular language constructs." It seems that using less macros is something library users will like.

https://laminar.dev/ might be what you need. Though I wish there was a more beginner friendly (I'm not from front-end world) tutorial for me to follow along.

Have you looked at Laminar and Tyrian? Especially Tyrian seems to be close to what you're looking for.

For Scala there is Laminar, which has an even flashier website with nice docs. I haven't tested it out though, as I have never used Scala.

I found this scala library called Laminar which looks super similar to solid. They use signals and has no virtual dom. State changes are represented by signals and events by event streams. Thus they seems to have feature parity with RXJS as they can model all sorts of async stuff. Best part is they get to keep writing their markup in C-style syntax than XML based JSX. It looks super elegant,minimalist and has type safety.

This is very true. I really hate svelte single file components. But then I tried JSX for breaking things down. I love solid but I don't feel really good about angle brackets within C style syntax. I saw this Scala library that stick with simple statically typed function syntax than html tags. I don't understand why people still wants to stick with xml like tags. In laminar markup is written like this scala div( h1("Hello world", color := "red"), inputCaption, input(inputMods, name := "fullName"), div( ">>", button("Submit"), "<<" ) ) I wish solid team makes their HyperScript syntax as performant as JSX.

Laminar (Scala framework) hasn't been mentioned yet so dropping it here as an awesome framework that support HTML-over-the-wire. It can be used together with React, HTMX, and many other frontend frameworks -- but doesn't have to be.

Scala.js core itself, which I maintain, does not need much innovation. We support all of Scala, and interact with any JavaScript library. That's what the core promises.

If you want to compare to Scala 3, it's worth pointing out that you can use Scala.js with any Scala version >= 2.12.2. In particular, you can use it with Scala 3 and benefit from all its innovations. ;)

Innovation comes mainly from libraries, notably UI libraries. Laminar (https://laminar.dev/) is a great example.

In terms of roadmap, we are mostly working on "boring" stuff: improving performance (of the generated code, and of the linker), fixing bugs when they get reported, etc.

Perhaps, when Wasm gets more features for deeper interoperability with JavaScript (manipulating objects notably), we will take another look at targeting Wasm. People usually expect all languages to target Wasm now, "because it's fast". Truth is, it's fast for languages with linear memory. There is no evidence yet that it will be fast for memory-managed languages with objects and virtual dispatch.

You might want to look at Scala, they have proper LSP support with metals which means you can write your code in vscode, neovim, emacs, or even fleet (the new jetbrains text editor).

Please write in the comments if you know of any language servers I should test it with. Currently I tested only metals and rust-analyzer.

If you are using nvim-lspconfig you can pass the settings as a Lua table to the setup function. For example, here are may metals settings:

Bazel support in Metals. I didn't spend all that time figuring out and adjusting Emacs/Spacemacs and making my workflow (almost) mouse-free just to scrap my config and switch to IDEA's rodent infested ways.

There is one small issue involving code completion returning inappropriate completions in some cases; https://github.com/scalameta/metals/pull/4414 will fix it, once it's included in a release. Perhaps that's the PR you saw?

It is, by quite a bit.

While the "Scala IDE" project is dead for all practical purposes, IntelliJ IDEA's Scala plugin is actually pretty amazing. There's also a VisualStudio plugin that does pretty much the same and is advancing by leaps and bounds. There are also interconnecting projects that provide i.e. language server or build server that are reused by other projects. It's pretty modular. Metals (https://scalameta.org/metals/) is amazing.

In general the language has become a wee bit faster to build, there was good progress with build times during the 2.12/2.13 cycles.

With Scala3 the language got a bit simpler; concepts that were implemented explicitly using (hehe) implicits got their own keywords and a lot of the opinionated boilercode that cause a lot of debates is now generated during complication and hidden. A lot of "standardization" has occurred.

IntelliJ has its own BSP. The other one is Metals. You can use it with many IDEs (vim, emacs, vscode, atom,...). Use it with emacs if you're comfortable with it.
