What is the require cache in Node.js?

What is the require cache in Node.js?

The require cache in Node.js is an object that stores all the modules that have been loaded using the require function. This allows Node.js to reuse modules instead of loading them multiple times, improving performance.

How can I clear the require cache?

You can clear the require cache by deleting the specific module from the require.cache object. For example: delete require.cache[require.resolve('module-name')];.

Are there any downsides to using the require cache?

Yes, one downside is that if a module's state changes, the cached version won't reflect those changes unless you clear the cache.

Can I modify a module after it's been cached?

Yes, you can modify a module after it's been cached, but those changes won't be reflected in the cached version unless you clear the cache and require it again.
