qqwing-wasm

qqwing-wasm packages the QQWing Sudoku generator and solver as an Emscripten WebAssembly module.

This package exposes the compiled module directly. After creating an instance, call callMain() with the same arguments you would pass to the QQWing CLI.

Install

npm install qqwing-wasm

Node >=18.3.0 is required.

CommonJS

const createQQWing = require('qqwing-wasm');

createQQWing({
	print: (line) => process.stdout.write(`${line}\n`),
	printErr: (line) => process.stderr.write(`${line}\n`),
}).then((module) => {
	module.callMain(['--generate', '1', '--difficulty', 'expert', '--one-line']);
});

ESM

import createQQWing from 'qqwing-wasm';

const module = await createQQWing({
	print: console.log,
	printErr: console.error,
});

module.callMain(['--generate', '1', '--difficulty', 'expert', '--one-line']);

Notes

• print captures standard output.
• printErr captures standard error.
• callMain() accepts the same flags as the QQWing command-line tool.
