    FastNoiseJS provides N-API bindings for FastNoise, so you can call FastNoise functions in Node.js.

    Installation

    $ npm install fastnoisejs --save

    Usage

    const fastnoise = require('fastnoisejs')
    const noise = fastnoise.Create(123)
     
    noise.SetNoiseType(fastnoise.Simplex)
     
    for (let x = 0; x < 10; x++) {
      for (let y = 0; y < 10; y++) {
        console.log(noise.GetNoise(x, y))
      }
    }

    API

    For more exhaustive documentation, refer to the FastNoise wiki. The example below highlights how fastnoisejs binds FastNoise's methods and enumerated types:

    #include "FastNoise.h"
    #include <iostream>
     
    int main() {
      FastNoise noise;
     
      noise.SetNoiseType(FastNoise::Simplex);
      std::cout << noise.GetNoise(21, 43) << std::endl;
     
      return 0;
    }
    const fastnoise = require('fastnoisejs')
     
    const noise = fastnoise.Create()
    noise.SetNoiseType(fastnoise.Simplex)
     
    console.log(noise.GetNoise(21, 43))

    Noise constructor

    const fastnoise = require('fastnoisejs')
     
    // Optional seed argument; must be an integer
    const noise = fastnoise.Create(324)

    Accessing enumerated types

    const fastnoise = require('fastnoisejs')
     
    // This is not an exhaustive list; read the FastNoise wiki
    const enums = [
      fastnoise.Simplex,
      fastnoise.Perlin,
      fastnoise.Linear,
      fastnoise.Quintic
    ]
     
    console.log(enums)

    Using FastNoise instance methods

    const fastnoise = require('fastnoisejs')
     
    const noise = fastnoise.Create()
     
    // SetNoiseType sets the algorithm for noise.GetNoise(x, y)
    noise.SetNoiseType(noise.Simplex)
     
    const noiseVals = [
      noise.GetSimplex(23, 43),
      noise.GetValue(23, 43),
      noise.GetPerlin(23, 43),
      noise.GetNoise(23, 43)
    ]
     
    console.log(noiseVals)
