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.

Hi HN, I’m Guillaume, the cofounder of Bearer, an Open Source SAST solution. After launching a few weeks ago here on Hacker News with support for Ruby and JavaScript stacks, I’m happy to report we’ve just released a new version (v1.2) with TypeScript support! In terms of code coverage, we use the same rules already implemented for vanilla JavaScript, but as usual, you can build your own. The rules list is here: https://docs.bearer.com/reference/rules/ It’s a first version for TS, but we believe that thanks to the pre-existing JavaScript support it should already…

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,…

I've spent the past few months building a language that is 99% compatible with CoffeeScript and 99% compatible with TypeScript. Essentially a reimagined CoffeeScript for 2022 that finished ES6s partially completed features, adds TypeScript support, and keeps the niceties of CoffeeScript. Example features: - Const assignment shorthand user := getUser() --- const user = getUser() - Parens optional and braceless nesting if x > 0 return --- if (x > 0) { return } - &fn shorthand nums.map &+1 --- nums.map($=>$+1) And a heck-ton more: https://github.com/DanielXMoore/Civet A big…

Hi HN, I’ve been building 'Fragno', a toolkit for building full-stack TypeScript libraries that work seamlessly across frameworks like Next.js and SvelteKit. Traditional libraries are built to integrate on either the frontend or backend. Glue code ends up being re-implemented for every project: API routes, documentation (OpenAPI), client-side integration, etc. With Fragno, you can write libraries that include API routes and client-side hooks/logic. Users can integrate a Fragno library into their application with just a couple of lines of code. This embeds the API routes and lets them…

I built FlouState because "4 hours of coding" tells you nothing. Was it 4 hours debugging or 4 hours building features? Very different. It's a VS Code extension that automatically categorizes your coding into: Creating (new features), Debugging (fixing issues), Refactoring (improving code), or Exploring (learning codebase). Example: Yesterday I "coded" 6 hours but it was actually 3.5h debugging a race condition, 1.5h refactoring, 0.5h tests, 0.5h exploring. Traditional time trackers just show "6 hours in TypeScript." Technical: Tracks file changes, debug sessions, and edit patterns locally.…

I built KubernetesJS because I was frustrated with the state of Kubernetes tooling for TypeScript developers. Most existing clients, like kubernetes-client, were last updated five years ago and rely on generating clients at runtime from Swagger specs. That approach works, but it lacks strong typing, good auto-complete, and tends to feel brittle in larger projects. KubernetesJS also uses the Kubernetes Swagger schema, but instead of generating clients at runtime, it generates fully-typed static TypeScript code at build time. That means you get excellent TypeScript support, predictable APIs,…

After almost a year of development and iterating, we just released Legend-State 1.0. It's the fastest React state library and is very easy to use, based on Observables (Signals) with fine-grained reactivity and built-in persistence. I'd love to know what you think, and I'm also happy to answer any general JavaScript performance questions if you want since I've gone very deep into optimizing . https://github.com/LegendApp/legend-state

Hi HN! RΞASON is an OSS Typescript framework for developing LLM apps that uses Typescript's interfaces to get structured output from an LLM. While there are other TS LLM frameworks, I think RΞASON fills a unique space in the market: it's laser-focused on only three areas and, most importantly, actively stays away from pre-made prompting & retrieval. I've been in the LLM space since GPT-3 originally came out, and I've always had problems with other frameworks, such as LangChain. I dislike that they focus a ton on out-of-the-box prompting & pre-made agents — I, as the dev, should be the one in…

Hi HN, I build this a few months back, thinking about improving it but wanted to share as is first to see what feedback I can get. I built it to be modular and with a clean understandable codebase in mind so easily extendable. I want to add more components to it maybe... Thanks! Will add link to the repo in a comment now
