JavaScript - Running different RegEx engines

I'd like to write JavaScript code that runs regular expression engines other than the one built into it and returns the matches.

My goal is to make a website where people can upload a RegEx, specify the engine and have the result shown to them.

After doing some looking I'm pretty sure that such a library doesn't exist, nor is there anything with any interest in running non-JavaScript RegEx. Nor was there for Ruby.

What exactly would this look like? The part that confuses me (not really sure how to begin) is interfacing with non-JavaScript code designed for other programming languages.

Thanks for the help.

Which regex engine(s) do you want to run? Why do you want to do this? Why can't you just execute some code in a language that runs on that engine? – Tom Lord Dec 10 '17 at 00:23
All of them, any of them. My goal is to make a website where people can upload a RegEx, test it against a string and have the result shown to them. I should probably specify that. I've also realised that this question is probably more relevant to JavaScript. Will update answer. – JackHasaKeyboard Dec 10 '17 at 00:27

You would need to run the different languages in back end. Use websockets to communicate between front and back. – charlietfl Dec 10 '17 at 00:36
@charlietfl That's a start. – JackHasaKeyboard Dec 10 '17 at 00:41

Could probably use heroku for example to set up several different environments and use one as master – charlietfl Dec 10 '17 at 00:45

@JackHasa Do you want to make this available to the public? There are many sites that offer exactly what you describe. Here are some: https://gist.github.com/fghber/44febf440c8dead56da92e50d4e02a03 – wp78de Dec 10 '17 at 00:48
@wp78de I do, it's a personal endeavour though. – JackHasaKeyboard Dec 10 '17 at 00:50
@wp78de that's a handy resource! – charlietfl Dec 10 '17 at 00:56
