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 Rust. Here's the original HN thread: https://news.ycombinator.com/item?id=43466221

I looked at their GitHub page, and started reading the source code. I do this for anything posted here that catches my attention, even if it's written in a language I don't understand. The code was relatively easy to follow, even though I'm not a Rust programmer.

Why did I decide to try rewriting it in TypeScript? For fun, of course! That was basically the only reason. I had nothing to do on a weekend and wanted to write code. It _did_ help with some challenges I was facing at $day_job, but that came afterwards.

I emailed the authors of the Rust version, telling them that I was working in a TypeScript version, and they kindly blessed me to publish it with a similar name.

Overall I'm very happy with it. The original authors provided an amazing foundation for a port, I had fun rewriting it and trying to adapt their APIs from Rust to TypeScript. As a bonus, it was immediately useful at work as well.

I appreciate any feedback or thoughts on it. Please check out the original project as well, since most of the hard work was done by them: https://github.com/thepartly/gatehouse
