GeaStack shows native apps built entirely in TypeScript and CSS
A GitHub example gallery lets one TypeScript/CSS codebase target web simulators, embedded boards, GeaOS, and Apple platforms.
What to know
- GeaStack lets developers write one app in TypeScript and CSS that runs on a web simulator, embedded boards, GeaOS, Apple targets, and inside a VS Code/Cursor extension.
- The framework is MIT-licensed overall, but embedded board support (targets and @geastack/chips) is GPL-3.0-only, meaning closed-source firmware built on those pieces requires a commercial license.
- The repo gained traction on Hacker News, reaching 100 points and 34 comments before being syndicated by aggregator bots.

I'll keep an eye on this, it seems cool - write once in typescript, compiler compiles typescript into native apps. Seems like it combines ideas from React Native (one language/application model across platforms), Svelte (compiles away high level abstractions to avoid a heavy runtime), and Flutter (own enough of the UI model to target very…

Author of tsonic.org here (which is very similar, but for Rust, C# and Mojo - WIP).One of the biggest complaints I get is about missing documentation on what TypeScript is not supported.For example, the following is obviously impossible: const a = eval("...something...."); or even: a: unknown, or a: any. The rest of it is largely doable. But…

It'll be cool to see how this compares with similar projects, there's a few of these jumping on the scene now.

Not apparent at first, but this is a TypeScript to c++ compiler at the core (https://github.com/geastack/compiler), with bindings for various platforms.
