Crystaldoc.info – Crystal Shards API Documentation Hosting
This is a website I developed in Crystal for hosting API documentation for Crystal shards (aka gems, crates, libraries, etc). It's built in Crystal itself and is using Postgres, Kemal, the built-in doc generation tooling, and Lexbor. I've been working on this for a number of months and I'm proud of where it's gotten. All feedback welcome! Repo: https://github.com/nobodywasishere/crystaldoc.info

In plain words
Crystaldoc.info is a website for hosting API documentation for Crystal shards, the language's package libraries. Built in Crystal using Postgres, Kemal, and Lexbor, it automatically generates and displays documentation for Crystal libraries in a centralized location. The tool is designed for Crystal developers and package maintainers who need a place to publish and access shard documentation.

Hi HN! I'm excited to share a project I've been working on for the past year: Docland. It is an API documentation browser that generates documentation on demand (through compilation, not LLMs) for Java packages. Instead of relying on Javadoc, the built-in doc generator, I created the engine from scratch to give the documentations a modern look, build fast search indexes, and enable link resolution to other packages. I built Docland because I constantly found it frustrating to locate and view API definitions when programming. You'd have to Google the function/class name, skip all the SEO…

Talanoa▲346Hi 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…
