node-uci is an implementation of the Universal Chess Interface protocol for node.js. In short, you can talk to engines (like Stockfish, Rybka, etc.) from node.js without any headaches. Abstracts away the pesky communication and parsing of UCI and provides a sane API to communicate with engines.
Through npm with npm install node-uci.
Usage examples and documentation
import { Engine } from 'node-uci'
// or
const Engine = require('node-uci').Engine
// async/await
const engine = new Engine('engine/executable/path')
await engine.init()
await engine.setoption('MultiPV', '4')
await engine.isready()
console.log('engine ready', engine.id, engine.options)
const result = await engine.go({ nodes: 2500000 })
console.log('result', result)
await engine.quit()
//promises with chain
const engine = new Engine('engine/executable/path')
engine
.chain()
.init()
.setoption('MultiPV', 3)
.position('r1bqkbnr/pppp1ppp/2n5/1B2p3/4P3/5N2/PPPP1PPP/RNBQK2R b KQkq - 3 3')
.go({ depth: 15 })
.then(result => {
console.log(result)
})MIT
