Ches

A small little game I’m making. You can play at https://ches.vercel.app.

Dev

For absolute beginners

You need to set up these:

• VSCode: https://code.visualstudio.com/
• Node.js: https://nodejs.org/en/
• pnpm: https://pnpm.io/installation

Then open a new Terminal and do:

git clone https://github.com/neongreen/ches.git
cd ches

Proceed with the next section.

Start

pnpm i
pnpm dev

Debug

chess and gameMethods are available in the browser console. Just type it. You’ll be pleasantly surprised.

To test unmakeMove, run:

pnpm bench:test
pnpm golden:test -s unrestricted

Typecheck and lint

pnpm check

Generating sample (golden) games

Useful to check that a refactoring didn’t change anything (the engine is deterministic right now).

# Needs to be run from the root!

pnpm golden    # regenerate all

pnpm golden -s <uuid1> -s <uuid2> ... # regenerate specific challenges

UCI interface

pnpm run --silent uci

Or with Mise:

mise run uci

Can’t push huge Git objects

git config --global http.postBuffer 524288000

React typecheck errors

Type 'import(".../@types-react-npm-18.0.26-d708995a34-10c0.zip/node_modules/@types/react/index").ReactNode' is not assignable to type 'React.ReactNode'.

Might be caused by having several react versions

UCI engine

See docs/uci.md for how to run the command-line engine and the self-play runner.
