Gatehouse-TS – TypeScript port of Rust's authorization policy framework

In plain words

Gatehouse-TS is a TypeScript authorization library with zero dependencies that enables developers to combine multiple access control policies to verify resource access permissions. Ported from the Rust original, it allows for flexible policy composition in TypeScript applications. The library is designed for developers building systems that need granular permission management and access control enforcement.

A flexible, zero-dependencies TypeScript library for authorization, based on the Gatehouse library for Rust - 9Morello/gatehouse-ts

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. Credits for the original API design, Rust implementation and usage instructions go to Hardbyte and Partly . Here is an example of how to build a role-based Policy and evaluate access with it. import { buildRbacPolicy , PermissionChecker } from 'gatehouse-ts' ; type User = { id : number ; roles :…from github.com

In the maker’s words, at launch

TL;DR Gatehouse-TS is a zero-dependencies authorization policy library written in TypeScript, ported from Rust. It allows you to combine different access control policies to check before allowing someone to access a resource. A few weeks ago, I saw a post on HN about Gatehouse, an authorization library written in…

  Typebase – A single-folder back end you write in TypeScriptAug 2026 · typebase.io · ▲119

  Hey 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…

  libmodulor – An opinionated TS library to build multi-platform apps2025 · github.com · ▲51

  Initially I started building this for my own projects. The main goal was to define a unified "blueprint" allowing me to develop multi-platform apps using the same code, without code generation. I wanted to be able to develop the same functionality on web, desktop, cli, server, mobile, whatever... I've been able to achieve this by relying on TypeScript, a 4-layer architecture (UseCase => App => Product => Target) and dependency injection. This mechanism allows me to use whatever tech stack I want, provided the good adapters are developed. For instance, I have pre-built ones : node express…

  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 built a hardware processor that runs Python▲983

  Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
