The Aho–Corasick algorithm (aca) is a string searching algorithm.

$ npm i aca
const aca = require("aca");

aca.find(keywords: array, text: string, [charset: string])

Search for keywords in text strings.

charset (optional, Unicode or ASCII, defaults to Unicode)

aca.find(keywords, text) // => { matches, positions, count }

Example

var keywords = ["h", "he", "she", "hers", "his"];
var text = "ahishers";
 
var result = aca.find(keywords, text, 'ASCII');
 
result.matches //keyword:positions
=> {"h":[1,4],"his":[1],"she":[3],"he":[4],"hers":[4]} 
result.positions //position:keywords
=> [[1,["h","his"]],[3,["she"]],[4,["h","he","hers"]]]
result.count //keyword:count
=> {"h":2,"his":1,"he":1,"she":1,"hers":1}
