Connect 4 Game Solver

C++ Connect 4 Game Solver with JavaScript bindings created using Emscripten.

Exports loadBook, analyzePosition, and onInitialized

Wait for onInitialized before calling other functions, or crashes may occur.

Loading a book is effectively mandatory to analyze positions with <5 moves played (as otherwise, the search tree is large and could take an extremely long time to analyze)

loadBook takes one parameter, the ArrayBuffer for the bytes of the book file.

analyzePosition takes one parameter, the sequence of moves played on the board as a string, with "1" representing first column, "2" second, etc. So "" is an empty board, "4424" is 4th column, 4th column, 2nd column, 4th column, in that order, etc.

Example Calls:

connect4solver = require("connect-4-solver")
connect4solver.onInitialized.then(() => {
    connect4solver.loadBook(new Uint8Array(fs.readFileSync("7x6.book").buffer))
    let evaluation = connect4solver.evaluatePosition("74637")
    console.log(evaluation)
})
