chess.js

The idea for this came from a comment on HN I read 6 months ago, where someone said: "I wish I could send a one-time link to my father where we could play chess against each other by re-visiting the same link" [1]. Of course lichess.org was mentioned, but it got me excited to build something simple with not too much scope creep. So that's what I tried to build: simple, without signup and supporting slow (make a move every week) or fast (sse based) games. Built with PocketBase[2] (customized to f.e. support web push), chess.js[3] and Claude it rekindled my interest in chess and I started playing it offline again and shared some game invites with friends. Hope some of you like it -> https://chessinvite.com [1] https://news.ycombinator.com/item?id=43267296 [2] https://pocketbase.io [3] https://github.com/jhlywa/chess.js

I'm curious as to why you wrote your own chess implementation - seems like this would have been much easier to implement with chessboard.js [1] and chess.js [2]. 1. https://chessboardjs.com/ 2. https://github.com/jhlywa/chess.js/blob/master/README.md

Cool! I've been thinking to make the exact same thing in Javascript using Chess.js and Chessboard.js https://github.com/jhlywa/chess.js/blob/master/README.md http://chessboardjs.com/ I got a half-working version and will opensource the code once it's ready. I think it could be a nice tool to help people starting with the game, but also as an analysis tool for more advanced players. [Edit] I just uploaded what I did so far on a server, just in case you want to take a look http://www.hotpixel.mx/chess/index.html my idea is to use little icons (now really terrible looking) with numbers and playing with opacity to give an idea of the strength for each square of the board. I still have some problems in some cases displaying incorrect numbers, but I hope to fix that as soon as I have some spare time :)

I started writing a chess game where rather than just two players there are two teams of an arbitrary number of players each who vote on what move to play next. Pitting yourself against a crowd of 100 other players should prove entertaining. Fun tech too.. using chess.js (https://github.com/jhlywa/chess.js/blob/master/README.md), chessboard.js (chessboardjs.com) and Firebase.com at the moment.

No, the application uses chess.js library found here: https://github.com/jhlywa/chess.js

"it would be tricky to get all the rules of chess into a JS file" Check out chess.js, https://github.com/jhlywa/chess.js, it does a pretty excellent job. The combination of chessboard.js and chess.js would result in a pretty sweet browser-based chess game.

This is a great write-up and is exactly the reason that ChessBoard is "just a board". Proper PGN parsing and legal move validation is a complex and independent problem that nicely fits into it's own library and should be separate from any display logic.
