Is it possible to override server side javascript from my plugin?

I want to update how NodeBB's caching works for my particular usecase.

To be able to do that, I need to update the get and set methods for:
src/cache/ttl and src/cache/lru

This is of course possible by directly editing these files. But is there some way to override them from my own plugin?

Since it's instantiated as new() by other functions, I can't directly require.main.require into my plugin and override the functions

Maybe you can override the set/get methods in the lru-cache module directly in your plugin. Try something like the below at the top of your plugin code.

const { LRUCache } = require.main.require('lru-cache');
const origSet = LRUCache.prototype.set;
LRUCache.prototype.set = function (...args) {
  console.log('custom lru set');
  return origSet.apply(this, args);
}

Perfect! Does the job super elegantly thank you
