Write native binary web apps with TypeScript and Express

In plain words

This TypeScript and Express framework enables developers to build native binary web applications using familiar tools. It targets programmers who want to create desktop or embedded web apps without switching languages or frameworks. The standout feature is the ability to write full-stack applications in TypeScript while compiling to native binaries, combining Express's server capabilities with direct system access for a unified development experience.

Express-style routing and middleware for Tsonic applications. @tsonic/express is a first-party Tsonic source package. It is authored in TypeScript, consumed through tsonic.package.json , and used with the @tsonic/js surface plus @tsonic/nodejs . @tsonic/express supports the default C# target. The package declares this in tsonic.package.json with "supportedTargets": ["csharp"] . Application code imports @tsonic/express directly; no target suffix is part of the public package name or import path. tsonic init --surface @tsonic/js tsonic add npm @tsonic/nodejs tsonic add npm @tsonic/express tsonic restore Quick start import { express } from "@tsonic/express/index.js" ; export async function…from github.com

  Mystral Native – Run JavaScript games natively with WebGPU (no browser)Jan 2026 · github.com · ▲50

  Hi HN, I've been building Mystral Native — a lightweight native runtime that lets you write games in JavaScript/TypeScript using standard Web APIs (WebGPU, Canvas 2D, Web Audio, fetch) and run them as standalone desktop apps. Think "Electron for games" but without Chromium. Or a JS runtime like Node, Deno, or Bun but optimized for WebGPU (and bundling a window / event system using SDL3). Why: I originally started by starting a new game engine in WebGPU, and I loved the iteration loop of writing Typescript & instantly seeing the changes in the browser with hot reloading. After…

  An opinionated and statically-typed TypeScript SDK generator2022 · easysdk.xyz · ▲81

  Hi Hacker News! My name is Sagar, I’m working on a startup called Speakeasy - we’re making all APIs self-service. The platform is currently in beta, but we’re independently launching this tool which you can use to generate language-idiomatic, statically-typed TS SDKs from any public OpenAPI schemas. We hope to continue iterating on this to give devs a way to easily generate high fidelity client SDKs for all the major languages. Inspiration for this product is from past experiences struggling with OpenAPI. I was originally optimistic about using the OpenAPI tools to build out our offering,…

  Crust – A CLI framework for TypeScript and BunMar 2026 · github.com · ▲95

  We've been building Crust (https://crustjs.com/), a TypeScript-first, Bun-native CLI framework with zero dependencies. It's been powering our core product internally for a while, and we're now open-sourcing it. The problem we kept running into: existing CLI frameworks in the JS ecosystem are either minimal arg parsers where you wire everything yourself, or heavyweight frameworks with large dependency trees and Node-era assumptions. We wanted something in between. What Crust does differently: - Full type inference from definitions — args and flags are inferred automatically. No…

  Talanoa▲341

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
