revery VS ts-sql

OCaml has actually put some decent effort into good GUI libraries, such as https://github.com/revery-ui/revery.

I never tried CoffeeScript since nobody pays me for it, though I am curious about ReasonML as an alternative, there's a Neovim front-end[0] coded in Reason that compiles natively[1], and supports existing VS Code plugins from the VSCodium plugin repository[2] which I still have yet to look at how the heck they pulled that bit off, but it is pretty interesting.

Maybe a technology like https://www.outrunlabs.com/revery/ would provide a better experience though it would require rebuilding the frontend, I presume.

It uses Revery which is still just javascript

No, I can’t say I’m familiar with a mature, cross-platform GUI framework which exists today that is any good. I’m keeping an eye on Revery, though.

There is an implementation of SQL that operates on a table shaped type, entirely at type level. For your amusement: https://github.com/codemix/ts-sql

There are a bunch of more practical takes that codegen types from your database and generate types for your queries, eg: https://github.com/adelsz/pgtyped

To me the second approach seems much more pragmatic because you don’t need to run a SQL parser in a fairly potato interpreter on every build

> If I would level criticisms at dialyzer it would be its sometimes difficult to read warnings, it’s speed (despite being multithreaded) and the race conditions in the VS Code plugin (which is looking for extra maintainers – if I had time I would help).

One of the advantages of TypeScript is that VSCode is written in TypeScript, and both VSCode and TypeScript are developed by the same company, so there's a really nice synergy there. I imagine Kotlin users feel the same way using Jetbrains products, and Swift users feel the same way about XCode.

Dialyzer looks interesting, but I can't imagine giving up on the expressiveness of TypeScript. Some of the things you can do with generics, mapped types, intersection types, template literal types, conditional types, and utility types are almost mind boggling. It's difficult to reap all of the benefits of static analysis without some of these advanced type operators. The type manipulation section of the TS manual is really underrated.

Someone for example wrote an SQL parser in TypeScript that requires no runtime code [1]. It can infer the types of an SQL query's result based on an SQL string without any runtime code execution. There was a similar project where someone built a JSON parser entirely using the type system [2]. There's also an ongoing discussion on Github about the the fact that TypeScript's type system appears to be a Turing-complete language with some other cool examples [3]. My point is that the type system is incredibly expressive. You rarely run into an idiom that can't be typed effectively.

If anyone saw this meme and thought, "damn parsing a type from a SQL query, that looks useful" (as I did), the source appears to be from here.

I mean, why stop there? https://github.com/codemix/ts-sql

Which allows for things like this type that implements a simplified SQL query parser checked against a provided 'database' object:

This project was my go-to "nifty but pointless" example for TS string literal types before this article :)

author of ts-sql[0] here, this looks great (and a way more practical approach!)
