    I built a web-based app for building websites. The main unique features are: 1. The ability to copy and paste any HTML and CSS into the editor with no limits. I was never able to find another app that could do this without some form of limitation. 2. CSS filtering, which means you can click on an element to view and edit the CSS selectors and rules that apply to that element alone. In many cases I've found CSS naming conventions like BEM to become irritating at certain scales, so this is an alternative solution. This part of the app needs some more development work but the concept is there.…

    Hello HN, For a few months I'm been working on a fun side-project to port the (awesome) chessboardjs library to an easily reusable and embeddable web component. The quarantine has finally spurred me to put the finishing touches on it. https://justinfagnani.github.io/chessboard-element/ It works in plain HTML files just by writing an HTML tag: And it works in any framework because it's just an HTML element. Styling is encapsulated and customizable with CSS properties and parts: chess-board { --dark-color: darkmagenta; } /* Highlight the e2 square in red */…

    Hi all, I'm currently working on my hobby project, and one of the fun constraints I put in was to build using as less dependencies as possible. I chose Go as it has a really good standard library, and all went well for building backend. But for frontend, I was wondering whether I should break the constraint and go for React. I tried options like Web Components, but I really didn't like the ergonomics and I didn't want to use jQuery either. Out of curiosity, I was exploring Go's html/template package to see if I can write UIs in a React-like manner. I found most of the online docs using…

    Hi HN, I've been working on this Sudoku web app for the past couple of years, on and off during free weekends and afternoons. I started working on it because I was bored during COVID, and Cracking the Cryptic had just become popular on YouTube, which got me wondering how hard it could be to make a Sudoku app. The main idea is for the app to understand the constraints and know how to solve Sudoku grids (and not just be a simple Sudoku drawing/playing app). When it comes to classic Sudoku, the solver doesn't support anything more complicated than X-Wing, but it understands the…
