TypeScript Editor that generates structured forms from TypeScript types

In plain words

This tool automatically generates structured forms from TypeScript type definitions, allowing developers to create and edit values that match specific types without manual coding. Built for use within Preview.js—an IDE extension for previewing React, Solid, and Vue components—it lets users quickly switch between different type variants and edit component props through an intuitive form interface rather than typing raw JavaScript values directly.

In the maker’s words, at launch

Hey HN! I've been doing a lot of work with the TypeScript Compiler API[1] recently as part of my work on Preview.js[2], an IDE extension that lets you preview React/Solid/Vue components. One thing I noticed is that even with great autocomplete and type validation, creating/editing JS values that match…

  I made this because building UIs in a lexical medium like code is super annoying. I have to pre-render what I’m making in my head, and then jump between the browser and IDE to test. I was inspired by the developer console in chrome and safari since I end up editing css there because it’s ironically more convenient. Hope it’s useful!

  Talanoa▲346

  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…

  Pipes puzzle (a.k.a. Net) on a hexagonal grid▲537

  Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So…
