Show HN: Advanced Chunking in JavaScript/TypeScript with Chonkie (ycombinator.com)
Hi HN,<p>We’re Shreyash and Bhavnick. We built Chonkie, an open-source library for advanced chunking and embedding of text and code. It was previously Python-only, but we just released a TypeScript version: https://github.com/chonkie-inc/chonkie-ts<p>Many AI projects in JS/TS (like those using Vercel's AI SDK or Mastra) rely on basic text splitters. But better chunking = better retrieval = better performance. That’s what Chonkie is built for.

Hyper Typing (pscanf.com)
Lately I’ve been trying out a few libraries that - in pursuit of perfect type safety - make their typings so complex that it makes them almost unusable, in my opinion. I call this approach hyper-typing, and I worry it’s becoming a trend in the TypeScript ecosystem.

Show HN: Gatehouse-TS – TypeScript port of Rust's authorization policy framework (github.com/9Morello)
Gatehouse-TS is a flexible, zero-dependencies authorization library written in TypeScript. It combines role-based (RBAC), attribute-based (ABAC), and relationship-based (ReBAC) access control policies. Port of the Gatehouse authorization library for Rust. The original authors did a fantastic job at creating an easy to use API, and were kind enough to let this library be named after Gatehouse.

Use the Gemini API with OpenAI Fallback in TypeScript (sometechblog.com)
If you want to use Gemini’s public API, but at the same time have a safe fallback in case you have exhausted the rate limits, you can use the OpenAI TS/JS library and a few helper functions. In my particular case I needed a type-safe solution for a chartmaker app with a fallback since Gemini’s gemini-2.5-pro-exp-03-25 model is restricted to 20 request/min.
