Node.js Built-In Modules

In the previous section, we extensively went over the events module and learned everything about using events to achieve easy communication within our applications. The events module is a built-in module offered by Node.js, meaning that we do not need to use npm to install it. In this module, we will discuss how to use the fs, path, and util modules.

path

The path module is a built-in module that provides utilities that can help us work with file paths and filenames.

path.join(…paths)

Path.join() is a very useful function when we are working with directories and files in our applications. It allows us to join paths together and output a path string that we can use in the fs module. To use join paths, we can call the join method and provide it with a list of paths. Let's look at the following example:

const currentDir = '/usr/home/me/Documents/project';
const dataDir = './data';
const assetDir = './assets&apos...
