npm install regex-search --save

use string search

import SearchValue from "../str/SearchValue";
import StringSearch from "../str/StringSearch";
import StringMatch from "../str/StringMatch";

/**
* define your search regex
* the text is changed to all lower case
*
* new SearchValue(ID, REGEX)
  */
  const sVal: SearchValue[] = [
  new SearchValue("KEYWORD_CORONA", "corona"),
  new SearchValue("KEYWORD_HOUSE", "house"),
  new SearchValue("KEYWORD_MERKEL", "merkel"),
  new SearchValue("KEYWORD_HUMAN", "human"),
  new SearchValue("URL", ".*:\/\/\..*"),
  ];

const searchStr: string = "This corona year many humans stayed in their house." +
" See more information on https://www.wikipedia.de/ there is some merkel for everybody";

// start string search
const search: StringSearch = new StringSearch(searchStr, sVal);
const sRes: StringMatch[] = search.search();
console.log(sRes);

use in code

import SearchValue from "../str/SearchValue";
import DataSearch from "../file/DataSearch";
import DataMatch from "../file/DataMatch";

/**
 * define your search regex
 * the text is changed to all lower case
 *
 * new SearchValue(ID, REGEX)
 */
const sVal: SearchValue[] = [
    new SearchValue("KEYWORD_CORONA", "corona"),
    new SearchValue("KEYWORD_HOUSE", "house"),
    new SearchValue("KEYWORD_MERKEL", "merkel"),
    new SearchValue("KEYWORD_HUMAN", "human"),
    new SearchValue("URL", ".*:\/\/\..*"),
];

// files create than give are skipped (crashes when trying to scan very big files)
const maxFileSize: number = 10000000;   // you should not scan very big files with this library

// path you want to scan
const path: string = "<your-path>";

// identifier for results
const dataId: string = "some-data-id";

// start the search
// this should take some time + there is no logging
const search: DataSearch = new DataSearch(path, sVal, maxFileSize);
const matches: DataMatch = search.search(dataId);
console.log(matches);
