Usage

To match or validate text/string, use valid function

    const { Regex, patterns } = require("validate-regex");
    const  OP = Regex.OP;
    
    // To validate number only
    const  isValidNumber = Regex.valid("124", patterns.NUMBER);
    
    // To validate email address
    const  isValidEmail = Regex.valid("dev@xyz.io", patterns.EMAIL, { flags: [OP.CASE_INSENSITIVE] });
    
    // To validate boolean value
    const  isBoolean = Regex.valid("abc", patterns.BOOLEAN);
    

To extract matched data/value from string or text, use groups function

    const { Regex, patterns } = require("validate-regex");
    const  OP = Regex.OP;
    
    // To extract digit and decimal value from number
    const { digit, decimal } = Regex.groups("124.56", patterns.NUMBER);
    // output : digit = 124, decimal = .56
    
    // To extract email address value
    const { email, domain } = Regex.groups("dev@xyz.io", patterns.EMAIL, { flags: [OP.CASE_INSENSITIVE] });
    // output : email = dev, domain = xyz.io
