conway-engine 
A moderately performant engine for Conway's Game of Life
Installation
npm:
npm install conway-engineUsage
conway-engine can be used both on node and on the browser. In the browser, loading it from a script tag will add it to the global scoped under the name of ConwayEngine
const ConwayEngine = require('conway-engine')
const conwaysGame = new ConwayEngine()
conwaysGame.tick()
console.log(conwaysGame)Examples
See the examples folder to get a better understanding on how the library works: https://niciusb.github.io/conway-engine/examples/
API
constructor([options])
options
options.width
Number of columns the world will have
options.height
Number of rows the world will have
options.initialWorld
Describes how the world should look like at generation 0. Can be an array or a function.
If it's an array, it must be an array with height children, which must be arrays with width children, being those a boolean determining whether the cell is alive
If it's a function, it must return a boolean determining whether the cell is alive. The first argument will be the y coordinate, and the second one the x coordinate
options.seed
If no initialWorld is provided, the engine will use a pseudorandom number generator to create the initial world, with a 20% chance of a cell being alive. The seed can be a string or a number
options.rulestring
The rulestring will be used to determine how the cells are born and die. It uses B/S notation. Check http://www.conwaylife.com/wiki/Rulestring to learn more
options.enableLastTickInfo
When enabled, cells will have a aliveLastTick property which is useful to avoid unnecessary redraws, but it reduces performance when advancing generations
options.wrapOnEdges
When enabled, the edges of the world will be treated as if they were adjactent to the other side
tick()
Advances to next generation
