What are some techniques for reloading Node.js modules without restarting the server?

There are several techniques for reloading Node.js modules, including using the require function, the nodemon tool, and dynamic imports. Would you like to know more about any specific technique?

Can you explain how nodemon works for automatic reloading?

Sure! nodemon is a utility that monitors changes in your source code and automatically restarts your Node.js application. You simply run your app with nodemon instead of node, and it will watch for file changes.

What about using the require function? How does that help?

Using the require function allows you to load modules dynamically. If you change a module, you can call delete require.cache[require.resolve('module-name')] to clear the cache and then require the module again to get the updated version.

Are there any downsides to these techniques?

Yes, there can be downsides. For example, using require can lead to unexpected behavior if not managed properly, and nodemon may not work well in production environments.
