[AskJS] Optional maximum evaluation time for RegExp
There are regex automata implementations like RE2 which guarantee execution in linear time and essentially solve this issue. You could consider node-re2 and re2-wasm if you're handling user-supplied regexes. Though note that back-tracking engines are faster on non-pathological input which is why they're the default.

Is there a node tutorial that's specifically made to show people how to use various popular C++ addons to improve performance?
A good way to approach writing native addons could be: * Read this intro article https://blog.sqreen.com/building-a-native-add-on-for-node-js-in-2019/ (disclaimer, I wrote this one) * Read the source code of some simple addon examples (https://github.com/uhop/node-re2, https://github.com/kelektiv/node.bcrypt.js#readme) * read the nodejs doc on native addons * read the libuv book if you want to handle asynchronous stuff in your addons * read Node.js source code

[AskJS] Optional maximum evaluation time for RegExp
In that case, a non-backtracking regex engine (e.g. re2-wasm) is your best bet. They guarantee O(n) execution time, so you won't have to worry about performance/hanging the browser.
What are some alternatives?
When comparing node-re2 and re2-wasm you can also consider the following projects:
regex - An implementation of regular expressions for Rust. This implementation uses finite automata and guarantees linear time matching on all inputs.
grex - A command-line tool and Rust library with Python bindings for generating regular expressions from user-provided test cases
SwiftLinkPreview - It makes a preview from an URL, grabbing all the information such as title, relevant texts and images.
foxreplace - Replace text in webpages
grex-js - A JavaScript / WebAssembly library for generating regular expressions from user-provided test cases
