    Usage

    Combines multiple regexes into a single regex using lookaheads

    Obviously, you can use the | (pipe?) to represent OR, but there is no AND operator in regex. But we can emulate an AND behaviour by using lookaheads.

    This lets you match paragraphs of text that contain ALL of a certain phrase, but in no particular order

     
      const regexCombineAnd = require('regex-combine-and');
     
      combinedRegex = regexCombineAnd([/a/, /quick/, /brown/]); // /^(?=[\s\S]*a)/(?=[\s\S]*quick)(?=[\s\S]*brown)[\s\S]*$/m
     
      combinedRegex.test('a cat is quick but a brown fox is faster'); // true
      combinedRegex.test('a cat is \n quick but a \n brown \n fox is faster'); // true
     
      combinedRegex.test('a quick fox'); // false
      combinedRegex.test('a quick brown'); //true
      combinedRegex.test('a brown quick'); // true
