SharpTS – Run TypeScript Natively on .NET via AOT Compilation
Hey HN! I'm the author of SharpTS, a TypeScript interpreter and ahead-of-time compiler written in C#. *What makes it different:* - Dual execution modes - interpret TypeScript directly OR compile to native .NET executables - Full C# interop - compile TypeScript to DLLs that C# projects can reference with full type safety *What works today:* - Core TypeScript: classes, interfaces, generics, async/await, decorators - Advanced types: union/intersection types, literal types, type guards - Compiles to verifiable .NET IL with performance comparable to hand-written C# - 80+ unit tests,…
What it does
In the maker’s words, at launch
Hey HN! I'm the author of SharpTS, a TypeScript interpreter and ahead-of-time compiler written in C#. *What makes it different:* - Dual execution modes - interpret TypeScript directly OR compile to native .NET executables - Full C# interop - compile TypeScript to DLLs that C# projects can reference with full type safety *What works today:* - Core TypeScript: classes, interfaces, generics, async/await, decorators - Advanced types: union/intersection types, literal types, type guards - Compiles to verifiable .NET IL with performance comparable to hand-written C# - 80+ unit tests, supports most of TypeScript's feature set *Why I built it:* I wanted to understand how TypeScript really works under the hood, and I thought .NET developers might appreciate being able to run TypeScript without Node.js. The AOT compilation to .NET IL was a fun challenge - mapping TypeScript's structural type system to .NET's nominal types required some creative solutions. *Current limitations:* - No npm module support (yet) - Some advanced type system features are still in progress - Standard library is partial (see STATUS.md) The repo has detailed architecture docs if you're curious about the implementation details. Would love feedback, especially from TypeScript or compiler folks! Example usage: ``` # Install dotnet tool install -g SharpTS # Interpret sharpts script.ts # Compile to .NET sharpts --compile script.ts dotnet script.dll ``` Happy to answer questions!

Spent a week in the break building a pre-compiler that brings type safety to runtime. Still pretty early, but generally does what it says. Looking for feedback, code that breaks it (check out the playground), ideas etc.

Typebase – A single-folder back end you write in TypeScript11d ago · typebase.io · ▲118Hey HN! I built Typebase, a library that gives you Convex's DX with Supabase's openness. After trying Supabase I liked how fast it is to spin up a DB and auth, but really didn't like using RLS and SQL for authorization. With Convex I loved how your server "lives" in your code, but disliked the DB model and the realtime-first defaults. With Typebase you just write TS files inside a typebase/ folder in your existing repo. You can define your DB tables inside a schema.ts file and export server functions that your frontend calls like local functions, fully typed. Auth is built in. Then one…

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
