regex-parser
Advanced tools
A module that parses a string as regular expression and returns the parsed value.
The regex-parser npm package is a utility for parsing regular expressions from strings in JavaScript. It allows developers to dynamically create regular expression objects from string inputs, which can be useful in scenarios where regular expressions need to be constructed at runtime based on user input or other dynamic data sources.
Parsing regular expressions from strings
This feature allows the parsing of regular expressions from string format into RegExp objects. The example demonstrates creating a RegExp object for a case-insensitive match of the word 'hello' and testing it against a sample string.
const regexParser = require('regex-parser');
// Parse a regular expression from a string
const regex = regexParser('/hello/i');
// Use the parsed regex to test strings
console.log(regex.test('Hello world')); // trueThe 'regex' package provides similar functionalities for handling regular expressions in JavaScript. It offers more comprehensive features for building, testing, and modifying regular expressions compared to regex-parser, which primarily focuses on parsing.
The 'safe-regex' package is designed to check if a regular expression is safe and not susceptible to ReDoS (Regular Expression Denial of Service) attacks. While it does not provide direct parsing capabilities like regex-parser, it complements its functionality by ensuring the safety of regex patterns.

I open-source almost everything I can, and I try to reply to everyone needing help using these projects. Obviously, this takes time. You can integrate and use these projects in your applications for free! You can even change the source code and redistribute (even resell it).
However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it:
Starring and sharing the projects you like :rocket:
—I love books! I will remember you after years if you buy me one. :grin: :book:
—You can make one-time donations via PayPal. I'll probably buy a coffee tea. :tea:
—Set up a recurring monthly donation and you will get interesting news about what I'm doing (things that I don't share with everyone).
Bitcoin—You can send me bitcoins at this address (or scanning the code below): 1P9BRsmazNQcuyTxEqveUsnf5CERdq35V6
Thanks! :heart:
